Attackers trick victims into calling them back on premium-rate numbers

Have you ever received a burst of missed calls from strange numbers in a short span of time? Such missed calls usually last for just one ring and it is strongly recommended that you DO NOT call these numbers back. This is an old scam that has resurfaced and we would like to warn our users against them.

These are international premium-rate numbers (IPRN) and people who call them are charged hefty rates which are transferred to the attacker. The trick is known as the ‘Wangiri’ fraud. In Japanese, ‘Wangiri’ means ‘one ring and cut’ and it is believed that this scam originated in Japan.

What is a premium number?
Premium-rate numbers are typically known as toll numbers and their origin can be traced to several European countries. Telecom operators offer a limited number of premium numbers which are acquired by businesses. Callers are charged premium rates (higher than regular calling rates) when they dial such numbers and the revenue earned is then shared between the telecom operator and the owner of the number.

Commercial establishments advertise these numbers for tech support, voting polls, competitions, directory inquiries, weather forecasts and more.

How a Wangiri scam works?
Once an attacker has acquired a premium-rate number he gives missed calls to thousands of cellphone numbers chosen randomly. Inadvertently, an unsuspecting victim calls the number back. An individual answers the call and tries to prolong the conversation under some pretext. All this while, the curious caller gets charged a large amount for the call. The rates range from Rs. 50 per minute to Rs. 200 per minute.

The latest slew of attacks has arisen from numbers starting with a +92 code. This code belongs to numbers from Pakistan but it is impossible to be sure as attackers could have used several masking techniques. Tracing the country of origin of such calls is a very difficult process and it can only be accomplished by law enforcement agencies. It is largely suspected that these calls do not originate in India. Hence, callers are charged international rates for calling these international premium-rate numbers.

It is an ingenious way of stealing money off victims. Prepaid users will find their credit drastically reduced whereas postpaid users would only come to know of these charges once they view their monthly bill. The best course of action would be to simply ignore such suspicious missed calls and refrain from calling them back. Quick Heal Mobile Security users can also utilize the ‘Call Blocking’ feature to blacklist such numbers and prevent them from reaching the device.

          Hi Nilesh,
          It is partially possible to trace numbers thanks to the Internet and other tools. But it is nothing to be alarmed about. There are many sources from which attackers get numbers but it is suspected that in this scenario they are just calling numbers randomly.
          Thanks.

      • Thanks man, I recently received a similar call from unknown No. when I
        checked in my call logs nothing found.. no number, no details. I called
        the customer support to find out more about this unknown .no guy but the
        customer care response was not that good. So I left it like that and forgot about it but when I have seen this ‘Message updated from QH center’ I was surprised and I am here to post the comment :) to spread awareness and thanks for your article Rahul much appreciated.

        • Rahul Thadani

          Hi Prathap,
          Thanks for sharing your experience. Everyone who reads this will benefit from that.

          • Yes Rahul, I too received such calls a number of times. One day I called back, but there was no response from the other side. To my surprise I was charged 90 Rupees for 1.15 minutes. I called the customer care but there response was not good and they just advised me not to call back on such numbers. The number begins with +92. Thanks for your update.

    • Rahul Thadani

      Hi Ram,
      The best thing to do is to be aware of such tricks and not fall for them. You should also spread this information with as many people as possible.
      Thanks.

  • thanks rahul,
    Get a no. of calls from +44 nos. and lucky that neither called nor answered , but got SMS and mail From RBI , Cocacola etc. as u won a lot of pounds and dollars and deposit few amount in SBI A/c will send the draft to ur address. DO we have to inform the local authorities abt. the call or the SMS/Mail for queries to be checked and help others to be aware of this quackery ?
    Thanks again.

    • Rahul Thadani

      Hi Shital,
      You should delete such messages and mails immediately. That is the best possible solution.

  • HI,

    I GOT MISCALL FROM +92 SERIES NOW.SO WHAT I DO AND GIVE ME FULL INFORMATION FOR THAT .

    • Rahul Thadani

      Hi Arvind,
      You should ignore such calls. Specifically, do not call back. If you can put the number on a Quick Heal Mobile Security blacklist, you should do that as well.
      Thanks.

  • me too. i got a call from +914443 starting number toaday .i tried to trace that number but the result is empty.

  • HELLO RAHUL.
    HOW R U?HOPE FINE.
    I REALLY THANKS A LOT AS YOU HAVE GIVEN SUCH A VALUABLE INFORMATION TO THE UNKNOWN VICTIMS.

  • I got a missed call from +375602605317.

  • I am using Airtel mobile service and got missed call twice from +92 call before one year. When I called back a person who was talking in HINDI told me “bhaiya aapka 13 lakh rupey ka draw nikla hai aur aap email address de dein taaki hum aapko information send kar sakein.”
    When I heared “bhaiya” from a person who claim to be call center representative I just shocked. After it I contact customer care they said me they can do nothing in my favor.

    I want to ask you can we take any legal actions against such caller? I suspect as the code suggest call is from another country we cant do anything.

    • Rahul Thadani

      Hi Ankit,
      That’s great observation and presence of mind by you. Keep it up. Thanks for sharing.

    • dude +92 is Pak’s code… better b careful….

  • this is very informative information and should to spread to as many people as posible ..

  • I received call from India number +91114???? . The caller told me that he is speaking from some XYZ co. You are a very good credit card customer and they want to give some benefit. Then he wanted to verify my identity as to I am the real person he is calling. So he asked me some question like what is on my credit card “MASTER CARD” or “VISA”. I suddenly sensed danger and told him that I do not want any benefit. Then I traced the number on internet it was a delhi number . I reported the incident to my ICICI bank. I mentioned the number to them hoping that they will lodge a complaint with police authorities.

    I received a routine reply telling me to approach police authorities and not to divulge my details over phone.

    Sometimes you get call and asking your birthdate so that they will update their record and wish you on your birthday. Never give your birthdate to such a caller. It may be used to change your password using forgot password.

    • Rahul Thadani

      Hi Prashant,
      We commend you for your presence of mind. It is wise to never divulge such details to random callers. Thanks for sharing.

  • Yes.. myself committed that fault in prev month..
    it happens that myself(owning BSNL prepaid) always get missed calls from my employees in respect of my business… so as a regular habit.. without considering that +92 indication before that MISSED CALL number i directly make a reply call & heard a sound of a lady who is making obscene noises & trying some attracting words… i was shocked … before anything speaking and operating that number.. i stopped that call… it costs me Rs.42.95 for those 25 seconds..
    No worry of that Rs.42.95… but will any wrong effects of my reply happens to my Cell number or My SERVICE… Please reply ME.. i have told all matters in such regard..

    • Rahul Thadani

      Hi Santosh,
      You don’t need to worry about anything else that can happen to your number or your service. What you hear on the other end is nothing to do with you. This is yet another variation to this trick. Thanks for sharing.

  • Thanks rahul for this important information. Generally everyone reply the unknown number.

  • I received a call from 252 which is a code for Boisar. I called back to realise that it was some shady characters.

  • I got calls from +371and+224.

  • Thanks Rahul…last week i recieved calls from+44 code number….like a fool i called back….but do u think someone we recently met has passed our number….or doing it her/himself…or the hackers are randomly picking the numbrs…pls tell its important….

    • Rahul Thadani

      Hi Annu,
      It’s impossible to be sure, but we feel that the attackers are randomly calling numbers. It is easy to develop such programs that automatically call numbers sequentially. Thanks.

  • i have been a victim of this in last week

  • thanks, for all the vital information,put this in meddia esp,t.v.news ,facebook etc.

  • Thanks Rahul for warning against those numbers………

  • thanx for giving such an important information

  • Thanks for the update….

  • only missed call or msg also thisway?

    i know it’s fake

    • Rahul Thadani

      Hi Karthika,
      This particular trick is only restricted to calls as of now, but that could change. Messages like the one you mentioned are another common trick as well.

  • Thanks for the useful information, is there any security that can protect my blackberry device.

    thanks once again, because i have the habbit of calling the missed call numbers, hence forth i will not, particularly unknown numbers

  • thanks for updating this

  • Thanks alot for giving information

  • O God it is not too much.In India the hackers gives missed call to smart phone holders.When the missed call received person call’s then the hacker will suck all details from the prey smart phone.Then the hackers start to steal the money from prey’s bank account.one of the new couple take the personel video in the smart phone.The hackers block mailed them with that video.So it is adviceble not to respond calls from unknowen persons.

    • Rahul Thadani

      Hi Raja,
      Thanks for sharing that information. It will prove useful to everyone. It is best to avoid taking calls from strange numbers and it is also advisable to install Quick Heal Mobile Security on your smartphone.

  • Hi… getting a similar call from a number starting with +37…. what about that…?

    • Rahul Thadani

      Hi Rajeev,
      That code is part of the country code for Germany so that is where this call originated from.

      • hi rahul,
        you are giving very good information.today i got a call with unknown number with +301 and i lifted that call. but he spoke only 20 sec and that i was not able to hear what he is saying. is that call safe for me or anyone trying to hack.please give information.
        Thank you

        • Rajib Singha

          Hi Judasingh,

          It is less likely that someone is trying to hack your phone. However, we recommend you not to call back on this number. And if you are frequently getting such calls, then you can use Quick Heal Total Security for Android to block calls and SMSs from such numbers.

          Regards,
          Rajib

  • yes… got another one from +92… ignored it… thanks buddy…

  • Thanks MR Rahul,
    I also received 4 to 5 missed calls from an unknown number staring with series +92.. i did not reply to them.I suggest that our govt. should do some thing to prevent such forged calls. what do u say ?

    • Rahul Thadani

      Hi Mahesh,
      Yes you are right, our Government should act. They do have departments that look into such matters though. We can all do our part in the meantime.
      Thanks.

  • Hi.
    recently i got a string of calls from number starting with +44.
    I got near about 10 calls from different numbers at an interval of 1 hr.
    /they were not missed calls but when i picked no one would say any thing and the call would disconnect after exactly 4 seconds.any idea what it might be?
    *my balance didn’t get deducted.*

    • Rahul Thadani

      Hi Shashwat,
      Thanks for sharing. +44 is the country code for UK. However, your balance did not get deducted because you did not call the number, merely answered. We suggest you do not make calls to such numbers.

  • I have recived phone like this ,,,but i avoided…so many time it was one ring and ,,,miscall…i call one time she took for ten seconds she cut down….then i never tried…and now it is not comming…..

    • Rahul Thadani

      Hi Praveen,
      +40 is the country code for Romania. Unless you have a relative or a friend there, this was exactly the kind of attack described in the post. Please check such numbers on the Internet before calling back. Thanks.

      • MR. RAHUL ITS CALLED INTERNATIONAL SHARE REVENUE FRAUDING(ISRF) .its stared from Columbia and its route through the simbox it is located to land the call on it it will terminate immediately and coasted you some how money as a deduction from ur account(cell phone).

        • Rahul Thadani

          Hi Ankit,
          International Revenue Share Fraud (IRSF) that you speak of is a kind of fraud wherein SIM cards that are enabled for international roaming are used to make local calls by victims. Thus they are charged international rates without their knowledge. The fraud that we are speaking of here is the ‘Wangiri’ fraud.
          Thanks.

  • Now a days mails that say-”You won a sweepstake lottery of Microsoft” or “your mail Id has won Rs.450 Crores in Punjab lottery” Mails from rich widows wanting help to transfer millions of dollars to India. etc. has become so common. Net has become accessible even to little children today. Possibility of youngsters falling for this is possible. As you said, wide communication is a must to fight this menace. Thanks for sharing the Wangiri Fraud with us.

    • Rahul Thadani

      Hi Biju,
      Yes there are many threats all around us today and we must be aware and vigilant at all times. If such information is shared quickly, a lot of people can be spared.
      Thanks for your inputs.

  • I got a missed call from this number last week and unknowingly i called the number without looking for the number and its originating location. They were offering some kind of reward won in a lottery. I immediately disconnected the call. this is totally foolish.

  • Thanks a lot Rahul for highlighting this. I have also received calls starting from +2399882138 & +905922112934.I have 2 cell connections, of Idea & Reliance.

  • Thanks for the update, Rahul. But my husband has already been the victim. He is the sales head of a company so he’s to attend many calls a day. He mistakenly did called back a number and it cost him around Rs.250.

  • Thank’s for the awareness. I dont’t in any case call back to unknown missed calls & neither do I take unknown calls. I will pass on the message to the people I know.

Withn one week his bill amount crossed more than 5000/- and thetelecom operator intimated us to pay the bill or else they would stop providing service to my brothers number.when we told them to provide us details about to whom the calls were made we found out that all the calls were made top brazil ,sudan, USA,dubai etc etc, in our live we hve never called in village also because we dont hve rerlatives or contacts outside mumbai….

  • THANKS A LOT QUICK HEAL. LOVE U MUAAAHHHHH

  • I have received a couple of calls with the +312 or some code.
    I always have my mobile with me and I have a curious habit of
    picking up the call in one or two rings. Will that give the
    callers a shock?? If so why not receive these calls, rather
    than call them back and become a fool ourselves?

  • thanks dear ,this incident happened with me too.

  • thanks for update and such information.

  • Never call back unknown number which is always going to be a good way to overcome such Premium number gangs !!

  • thanks for such a wonderful and important information

  • Do these call scammers call from Indian mobile number also or only from international numbers starting from +

    • Rahul Thadani

      Hi Ashish,
      A majority of these scammers have used international numbers as the rates applicable to international calls are higher. But it is possible that a few Indian numbers have been involved as well.
      Thanks.

  • Hey, thanks Bro, i also got one missed call on 21 jully number starting with +923057126023 as soon as I read that number starting with +92 i didn’t call back. Well thanks for detailed information provided.

  • I recieved call from +447937949157 ,and +447937947112 un known nos to me.
    I did not call them back,
    Thanks for your advice.

  • If you Recieve them what will happen, ???

    • Rahul Thadani

      HI A.P.Dwivedi,
      If you receive the call nothing would happen in most cases. However, we cannot discount the possibility that receiving a call might lead to another form of attack.
      Thanks.

  • Dear Rahul, this is very useful information u have given to QH users. I have some tips for this. U can try out.
    - If these calls are International calls , then they will be of the pattern
    [+ISDCODE (10digit your no.)] e.g. A) if call is from Pakistan then it will be [+929912345678]. Here +92 indicates ISD call. B) In case of call within country it will be [+919912345678].
    C) However this may confuse with subscriber of TATA .But then within country no.will be [+919212345678].
    D)As such one should be cautious and call back only after ascertaining 10digit mobile no. & prefix ISD code.
    E) In case of calls from landline it will be slightly tricky as many STD code appears with + prefix . However here also 10digit formula applies. After +91 the telephone will have [(STDCODE TEL NO)]=10digit. i.e. call from mumbai will look like [+91 2223456789) & call from Shillong will look like
    (+913642345678). All STD calls have prefix as “0″ or “+91″ but ISD will have “00″ or “+xy” any thing else then 91.
    F) On very much safer side go to Phone setup, search for “Call Barring ” feature & Bar outgoing International calls. This will help in restricting ISD calls.

  • Is it possible that those people would call again and again on that same number? ’cause my mom was getting missed calls from the same unknown number at regular intervals of time…
    And are there new numbers coming up? recently i got a call from a number starting from +33

    • Rahul Thadani

      Hi Tannavi,
      Yes it is possible to get repeated calls from some of the numbers.

      • Can we get rid of these numbers by filing a complaint at the network offices?

        • Rahul Thadani

          Hi Tannavi,
          That is certainly an option. But a lot of comments that we have received have stated that calling the network offices has not really provided helpful solutions. Nevertheless, you can call them and inform them about these numbers so that they can do their part.
          Thanks.

  • THANKS RAHUL THADANI …… For the UPDATE…

  • I got a miss call recently..but when I called back, the person asked “who are you”…… and when I read this, I got scared, but slowly realized that it was nothing of that stuff. Well, thanks..

    • Rahul Thadani

      The best thing to do in case of such calls is to not call back. You can also try contacting your service provider to inform them about the number. Also, if you own a smartphone you can utilize the call blocking feature in the Quick Heal Mobile Security product.
      Thanks.

  • thanks,

  • Dear Sir, I am Mr.P.Leijat Wangsuham Konyak of district on of State Nagaland (India). I would like to draw your kind attention for favour of your kind necessary step please Sir. My recent victims and an incident is such that on 7th of July 2012 i received a message through my email id from Coca-Cola Company United Kingdom (UK) stating that my email id have won a prize money of $500,000,00 GB Pound (Rupess Five Hundred thousand Great British Pounds) in the Coca-Cola Promotion Lottery draw in London United Kingdom. In the next mail they asked for my details and home address as their company representative (Agent) or the senior UK diplomat would come to my home town to hand over that the prize money. they said one of their company agent name Mr.Johnken is arriving at the Indira Gandhi International Airport New Delhi and contacted me through which i had given my contact number ans said the Indian Airport Authority Custom clearance charge is Rs. 22,500/- which charged at the Airport and said he would be moving

    • Rahul Thadani

      Hi P.Leijat Wangsuham,
      Regretfully, you have fallen for one of the most common email scams. You need to contact your local authorities to report this matter. You must never believe that you have won a lottery that you have never bought a ticket for. All the best for your situation.

  • yes it is helpful for us. thank you.

  • today i got 6 calls from a no +911204724390 from1232 to 1735 . 4 times i received and rest twice i disconnected. i’ve no idea who’s doing this mischief.also in past few days i received miscalls from +92 nos several times.

  • Hey but how we can trace the number..???
    can u give any informaion about it..??

    • Rahul Thadani

      Hi Anshul,
      There is no way to trace the number as law enforcement agencies are the only ones who can do this. However, you can search for the country code of the number that calls you and find the country of origin, via the web.
      Thanks.

  • Thanks a lot, for such precious information. Actually i have been receiving such calls from no starting with +92….. but i never picked call suspecting it to be a hacking call. Well Now I am sure not respond such calls anymore and to educate about this to my frenz. also.
    Well please be kind to tell us whether same risk lies in calls from nos. starting with +91…..
    Further I have heard that there some callers who also behave in this way, and attending their calls or replying to them results in hacking of ours’ no., in which all our calls and messages get recorded somewhere. Is it true? If yes, how to safeguard ourselves….

    • Rahul Thadani

      Hi Jai,
      The same risk is there with numbers starting with +91 too but since these are numbers from India there is only so much one can do. Usually this scam is seen with international numbers since the rates are higher. If you receive a call and find it suspicious you must immediately hang up. Moreover, if you use a smartphone you should consider installing a security suite like Quick Heal Mobile Security for enhanced protection.
      Thanks.

  • Sir a hell of lot of times on my mother’s cellphone i have received messages
    of winning $200,000,000,000 .it never ask for bank details but ask for name and valid address,also at the end of the message some [///] are made.
    So what i should do ?

    • Rahul Thadani

      Hi Shrey,
      It is best to not respond to such messages. That is the best course of action to take. If the phone is a smartphone you can install Quick Heal Mobile Security and utilize the various features that are provided.
      Thanks.

  • RAHUL, YOU DONE VERY GOOD JOB YAAR. THANK YOU ONCE AGAIN.

    I RECEIVED THIS TYPE OF CALLS FROM PAKISTAN AND UAE FROM

    my query is what would be result, shall this to be charged to my phone bill (post paid).
    if any one have the answer please let me know.

    • Rahul Thadani

      Hi Sumit,
      +30 is the country code for Greece. If you have received the call then you shall not be charged anything. However, if you called the number back then you would have been charged money.
      Thanks.

  • Sir, thanks for the information. Old age peoples like me will definitely help this. With regards.

  • thanks rahul. thanks a lot for taking initiative to make us aware of those scams. But one thing i want to inform that at about 9 months ago, i received a miss call from a number starting from +2. like other victims, i made a call back in that number and some one received my call and start speak(male voice) in HINDI. even he started with saying “namaste”. soon i got that he had an intention of making unnecessary prolonged conversation, and then after 5 seconds, i disconnected. i was charged Rs. 12. my question is that was i surely became the victim of only stealing money and nothing else???? is there any possibility that my phone number had been used for any other unscrupulous purpose or whether my phone number get involved in any kind of unsocial or terrorism activity?

    • Rahul Thadani

      Hi Subhajit,
      So far this scam has only been used to steal money from people. We do not believe that your number could have been used for any anti-social activity like you fear.
      Thanks.

  • yes i have receive a call from +5432169667358, can i know country code of dis no.?plz…..is dis the same scam …plz tell me

    • Rahul Thadani

      HI Siddharth,
      +54 is the country code for Argentina. It is possible that you got a call from there under this scam, but we cannot be completely sure about that. It is best to not call the number back.
      Thanks.

  • Hi Rahul,

    Thanks for this info. I was searching if some one had posted about it. I just now I got miss call from +2399825611 and once called backup few girls randomly picking the phone each time and talking very sweetly. They don’t no English properly but trying to adjust. Seems to be from outer India or Pakistan.

    If you say your location blindly, they saying they also from that location or nearby location and trying to make friendship. Main idea is to keep us in phone and get the charge credited to their lobby. I had backlisted these number in Blackberry servers and that was my main objective. But internationally Telecom authority have to do strict measure to stop it.

  • Thanks a lot rahul

  • Just got missed call from +2399882138 and i started googling to know that which country has this ISD code and found yr blog.

    Appreciated a lot dude. Keep doing well

    Thanks :)

  • yes dear, just now my friend got a call from +24 and the lady opposite side introduced as Sonia and started chatting and within seconds logged off. abt Rs100 is deducted from the account.

  • Just got 2 missed calls from +246866549. I tried calling them but fortunately I was out of India last month so my telecom operator has deactivated my ISD services. Now when I searched google before calling back on this number, I found this blog which is very useful. Much Appreciated.

  • Hi Rahul

    Regards

    • Rahul Thadani

      Hi Sunil,
      This is just a trick to convince you to call back on these numbers. If you do not call back you will be safe from this scam.
      Regards.

  • Dear rahul,when i call back at +4065 ,dialling number doesn’t exists …can it be a call fro internet service or likewise????

    • Rahul Thadani

      Hi Sunil,
      If you have no idea about the source of the call, it is advisable to not call back on the number. This is part of the scam that we have mentioned in the post.
      Regards.

  • rahul yesterday i got missed call frm a number starting from 44. I have not understood and called back to that number. I heard some recording and disconnect the call. and that call cost 20 rs. for 2 mints. I am very worried now. I want to ask u that are they only utilize that money or they also can copy my phone details. i have also talked to customer care but their response is not good. what should i do now. plz advise…….

    • Rahul Thadani

      Hi Arnab,
      No they will not be able to get your phone details. This scam is only about making money through these premium-rate numbers.
      Regards.

  • Thanks Rahul for such important information. Recently I have got calls from 2-3 Indian numbers between 11pm to 6 am, next day when I called them back to know who it was, they said they have got call from my number. how is this possible? What should be my action on this? Is this some kind of trick by pranksters? Do I need to lodge complaint?

    • Rahul Thadani

      Hi Sushil,
      If you were charged normal rates for this call then it cannot be a part of this scam. However, it could be another mode of attack. When you speak to the person on the other line and it seems suspicious, just hang up.
      Regards.

  • Hii Rahul
    I just got a missed call from a no. +242050823281 but internet says dat no country has an ISD code of +24.
    Do you think dat it is possibly a wangiri call.

  • hi guys.. I too just got a call from +242050823283 and I missed the call. But i dint activated ISD. So couldnt call back. Just googled for ist code and came here. THanks for the information.

    I got the call around 12 25 AM Oct 21 (midnight).

    This number looks similar to the one that anup has posted..

  • Am also got miss call from this no…+242050823283

  • I missed a call from exactly the same number. Did pick it up some two three times.

  • Today i got a call from +911204724390
    They said its a customer care call from Axis bank, i spoke for 1 min 15 secs and tried calling back, it says that no such number exists.

    • Vinay Das, I also got few calls from the same number today. When picked up, nobody responded. The STD code 120 belongs to Ghaziabad.

  • hi, bro same here with same number 923057126023
    11:32am
    5 nov,2012

  • Great effort.
    Thanks a ton…

  • i received this stupid missed call at 6 AM while I was deep asleep, since lot of my work is international I called back and heard the recorded message, so i hanged up ! later a bit of goggling and found your link, it explains everything ! the number was +24105328376

    One good way to differentiate is that if you call back, the call will be immediately picked up. You can hang it back the same instant. you will loose some money, for sure, but it wont be more then 20-40 Rs. Its the only way for those who actually make ISD calls.

    If you use android phones, you can use call blockers applications.

  • I too did received calls from the following numbers during odd hours
    1. +12173989544
    2. +381
    3. +15167469209
    4. +301
    5. +17188229084
    6. Unknown number – No number
    7. +16306539660
    8. +13034998790
    9. +17038802686
    and also +24105328376

    The person on the other side do speak some non sense.
    Do these numbers also belong to the scam mentioned here.
    Numbers seem to be masked.
    Is there any way to unmask these numbers?

    • Rahul Thadani

      Hi Bhab,
      Yes this seems to be a part of this same scam. It does not seem like the numbers are masked. A simple Google search can show you which country these numbers originate from.
      Regards.

      • Hi Rahul,

        Thanks for the reply. I tried finding out the country from google, but the caller speaks in Hindi which is weird to know that the ISD callers from some countries speaking Hindi. Also it is unlikely that the same mobile number is attacked from these many different ISD numbers. I tried to find ways to unmask the numbers but could not.

    • Hello,
      I’m french and I live in the suburbs of Paris.
      I often get calls from this number “+12173989544″
      which is also in your list.
      But this is not an international prefix.
      Did you receive answers to your question.
      I never responds to these calls, the answering machine and I just the following message: “Goodbye”

      Regards.

      Jean-Luc

      • Rahul Thadani

        Hi Jean-Luc,
        +1 is the country code for the USA. It is possible that this call originated from there but it is hard to say for sure. The best thing for you to do is ignore the calls as you have been doing already.
        Regards.

  • Hi Rahul,

    I too got a call from +92-3067057762 number today. They were saying that i have won some 25 lakhs as a lottery amount. As i heard some time back about such calls i disconnected the call after hearing this things. I hope that they have not cloned my number. I am really afraid now. I called the service provider to know the charges of my last received call but they were unable to provide me the details of the charges they i may have incurred receiving that call.

    • Rahul Thadani

      Hi Anjali,
      You will not be charged for receiving such calls. Since you hung up quickly, there is no other threat you are susceptible to.
      Regards.

  • i rcvd mis cal thrice from this no. +914043405470

        thanx a lot….

  • Can someone tell me origin of no. +911400850805 rcd on mb in Delhi? no one spoke after the phone was picked. Also, dial back seems not possible using prefix 00 1400 850 805.

    • Rahul Thadani

      Hi,
      Numbers that start with ‘+91-1400′ are telemarketing calls that originate from India. The Government has made it mandatory that this prefix be visible to receivers.
      Regards.

  • I am receiving call from +912242137000 & when I am receiving it, it starts calling back to this no. back.

  • Hello Rahul
    I just bought an uninor sim.. I am getting bulk of miscalls and sometimes calls from some numbers. I am little afraid of this now. Is anything I can do?
    I talked customer care 5 times and blocked 12 numbers but everytime now there is a new no. Please help me….
    I can give you some numbers…
    1.+1942942250
    2. +16077349187
    3. +8801942942250
    4. +15124770300

    • Rahul Thadani

      Hi Raj,
      It is hard to say whether these numbers are fake and part of the Wangiri scam. They could also be potential telemarketing calls since you have got a new SIM card. As solutions, you can continue blocking these numbers. You can also register your number as a DND (do not disturb) number to avoid marketing calls. Lastly, do not call back on these numbers if you are doubtful.
      Regards.

  • Thank you Rahul

    Appreciate the information

    Found you post while trying to see who called.

    Have been getting calls in quick succession from

  • I got a missed call with +88 (Bangladesh),
    I was amaized,
    then just waited a day and did a ‘one ring and cut’,
    with in a minute got a missed call with +1 (USA),
    then I was sure it is a fraud case (some of my friends travel to Bangladesh,I needed to be sure),
    and looked it up in QH’s blog,
    thank you for this detailed information.
    :)

  • Hi Rahul,

    I received a call today from +4065 but didnt pick the call. I was trying to google the number and landed in your page.

    Thank you for detailed information on IPRN number and how it works. Its really helpful.

    My question :
    - is +4065 a IPRN number and can we tracked from which country the call was received?

    - How can i stop receiving such call?

  • aaj mere no. Par +34 se call aaya tha. Acha hua ye info. Maine pad li thi. Thanks sir.

  • i received a call from +243820394844 at 2:16 pm India, time at the other side was saying ” hi i want to talk to you ,muje tum se baat karni hai call me back call me back ” i was confused i have not called back and went to sleep ….. what should do now ?

    • Sanjay Katkar

      Looks like this is a new scam. Avoid responding to such calls.

  • hi rahul

    today at around 7.30 my phone restarted on its own but i ignored it as my phone is old junk of LG. but a hour later when i tried to call my friend , the IVRS said that i dnt have any balance. i was surprised as i was having a 45 rs balance just few min earlier. when i checked my dialed list there was outgoing call from my no with duration of 4.06 min. and the no was +447968637858.

    i m sure that i have not made any calls thought my phone shows and my operator says. what should i do if my phone is hacked?

    • Sanjay Katkar

      This is most probably premium number calling Trojan. You need to install Mobile Security in your smartphone to protect it from such Trojans. You can download free trial version of Quick Heal Mobile Security from Google Android market.

  • i also got miss call from two numbers,and I called back to one number,he told me, he is calling from karachi,he told me your number owned 1 crore rupees, and he given me one number starts from 0092 something (i forgotted),it is computerised, it will answer, how can u get the prize, for this i was charged 39 rupees, his number starts from +92039662092, another one is +923044389675

    please beware of this frauds

    Thanks for the update.

  • Hi,
    This morning I got call from ISD nos. but as I avoid picking unknown nos. I did not take the call but the caller kept callig continuously and each time the nos. would change. The nos. are

    +21350065730

    I don’t understand the purpose of these calls as it does not appear to be call back fraud. Does someone has any idea about these calls???

  • My female friend has been receiving calls from a +44 number since some time. Its a lady dowsing in Hindi from the other side. Skill she all she does is abuse and ask about her whereabouts and these are proper phone calls. No missed calls as such. She patched me in, that lady heard my voice, asked who i am and disconnected. Any idea as to what this is?

    • Rajib Singha

      Hi Goks,

      It cannot be said for certain whether the caller is an online scammer or a miscreant. If the call is becoming a nuisance, then you can lodge a complaint with the police. Alternatively, you can block the number with the mobile security solution that Quick Heal offers. To know how this product can help you, visit http://www.quickheal.co.in/quick-heal-mobile-security.

  • I have been sent a message saying that these calls download all details and data from the phone in 3 seconds. Is that true?

    • Rajib Singha

      Hi MS,

      The message might be hoax. However, to be on a safer side, we would advise you to install a security software on your phone. This way you can prevent an attacker from downloading any data from your phone.

  • Hi Friends,

    I am also receiving one ring miss call from many international location. My phone balance was hugely deducted when I called back. After calling it back… its either taped message in unknown language or just system ring. That’s how I walked into trap.

    After I was cheated in such a way, I decided not to call back nor to pay attention to such calls. Moreover I receive such call at any time .. day or nigh or midnight or dawn. I just ignore them. If some one has to talk me from an international location, he will either allow me to pick up the phone ….(will not disconnect with one ring only) or will call back to me again even if I miss his call.

    I think, these cheaters may get our phone numbers from job portals where we register our all information with contact details.

  • HiRahul,

    Thanks for sharing this.
    I also got missed call from CONGO Countrys’ Number.
    Number was : +242-800101352 (One Ring And Cut)
    This is my nature that to any unknown number I never called back if I ever got any missed call.

    But I was curious about to know that how my number would be known to any another country’s person.

    Then came to know through True Caller that this number was shared by 231 people as a spam.

    Seriously you are right that this may be used for getting huge amount from your balance.

  • Good your site

      Hi Sajan,

      Unfortunately, we do not have this call block feature for tablets wherein you can block all incoming calls with a particular prefix. One solution for you is to add these numbers to the blacklist and block them. I believe this is something you are doing. Unfortunately, this will be a bit tedious for you as each number will have to be entered individually. Another option is to block all calls from non-contacts. This also may not be the ideal solution for you.

      We have noted your feedback regarding this feature and will work towards implementing it in future versions and updates. We apologize for the inconvenience.

      Best regards.

  • Just received an unknown call from Romania +40 518907052. A lady speaking slowly English, telling she is from some sort of Global Technician company, which has the permission to give support to all windows users. She was telling that there was some ‘very dangerous files’ infecting many windows operating systems. The reason she was calling was the hear if i had a certain program in my program files folder.

    Before we made it this far she wanted to know what antivirus program i was running. I then changed the subject and asked for her full name, and if they had website i could look into. She answered that the company behind was called Azuri and that i could find all about them at google. In the meantime I’d already search for this company and only found a solar power company. I told her that i was already looking and that i only could find this Azuri Technologies and continued saying that I couldn’t understood how anything about her call was related to a power company. She then suddenly hang up on the phone without saying anything…

  • I got an message from this no 9555729465 saying your GSM no. has won Rs 2crore 35 lacs INR in 2014 ICC Cricket award UK/India to claim send name /address/phone/age/sex/occupation to ukiccclaims@xbmail.com
    Plz…….tell me what to do

    • Rahul Thadani

      Hi,

      Kindly ignore this message as there is no such award. This is a scam.

      Thanks.

  • Hi Rahul,

    I too received the call from the number starting with ISD code +44 and sicne I was in a meeting, I answered the call but there was no one on the other end. The call lasted for almost 10-15 seconds.

    I just want to know whether answering calls from such numbers is also a risky venture, and if so what precautions I shall take hereafter, since I was on their call for 10-15 seconds.

    I have heard from some people that such callers can steal details regarding credit cards and other private things from our cell phones.

    How is it possible for them to do so?

    Your answer would be appreciated.

    Thanks

    Ranjit Hirode

    • Rahul Thadani

      Hi Ranjit,

      Answering calls from such numbers is not risky, at least not right now. But it is possible that attackers may soon devise a way to gain information in this manner as well. The best thing to do is not answer calls from suspicious country codes, unless you know someone there. Stay aware about the popular country codes. Also, if you pick up a call like this, or receive several missed calls repeatedly, do not call back on that number.

      Best regards.

      • Thanks Rahul!

  • Just started getting calls today from Romania. Did not answer of course but the number traced back to a forest in Romania. +40(251)732-37 was the number that called me. Been searching for an explanation and I think this is best on this website so I’m posting the number in case anyone has it happen to them and they gts. Thank you

    • Rahul Thadani

      Hi Jerry,

      Thank you for sharing this.

      Best regards.

  • i had just got a call from the number stating with +92 i thought anonymous and it was shown that it was from pakistan.so i just thought to know about such anonymus calls and i found your post.Thanks for the post..make ppl aware of this ,so that they will not fall in this trap.

  • Hi Rahul…thanks for information….I just got a missed call in morning of 23 May 2014 from an number with code +92…I was unable to answer as I was busy in some work..But I called that number ..hopefully I was said by the company that u don’t have this facility on your mobile…On the same day that night I received another call from that same number and I accepted the call….there was a person who said “Hello”….Than I also said “Hello” and he just ended the call…today is 24 March 2014 when I read your blog…Do I need to worry because I didn’t called him basically ….

    • Rahul Thadani

      Hi Kamin,

      Your concern is real but you need not worry as you did not call that number back. So no harm can come to your device and your data.

      Best regards.

  • Yes Rahul, I got a miss call from +2247……, when called back, 11 rupees had deducted from my balance in 5 seconds.

  • First of all thanks a lot for enlightening the Aam Aadmi. I too got lot of missed calls earlier it was from Toll free like Nos, I did not answer. Now I am getting a miss call from +918040204020. After carefully scrutinizing the Mob No, it seems it is premium No. Means the “Wangiri” fraud surfaced in India also………..

  • Hello friends .
    Today i recieved a call from +279020675.
    As i am from punjab he was also speaking punjabi.
    he asked me that what is ur name.
    I told him u first tell whom u hav called. He said i called Atal bihari vajpayee. I hang up.

    so my question is that was it a fraud call or it was a call from the internet like the ones which come from applications such as textme( textme gives number starting from +44..)

    • Rajib Singha

      Hello Prabhjot,

      You took the right measure by not giving the caller your name, and by hanging up. Most probably, it was a fraud call or at the least, a prank call. It cannot be said for certain that the call was made using the Internet.

      Regards,

  • hi sir,
    i had received a call from the no. +4065,one person speaking unnecessarily and suspend the call. Then i tried to make call to that number,but i heard that the number doesn’t exist,which number it is

    • Rajib Singha

      Hi Kiruba,

      Thank you for writing to us. As advised in the post, please do not call back such numbers. Although no one may speak from the other end, the call may cost you for nothing.

      Regards,

  • These number eg +4065 can be used for many purposes but most of the time it is used for illegal means.

    In some countries, they will call you claiming you won some prizes and as part of verification they will like you to revel your name,DOB,address etc etc… Effectively what they have done is got information about you from you. These information can be used for many dirty purposes in future.

    In some countries, these numbers are used by loan sharks. Then will call you and threaten you to transfer some amount (1-10K) to a particular bank account.Failure to do so, they will claim they will harm you and your family. Possibly they could have got your information as mentioned in the above paragraph.

    How other ways do they get our information ?
    1) Surveys… if you have habit of filling up surveys, you have given away your personal particulars.
    2)Some marts may give you membership discount cards and for that you will be revealing your information again…
    3)In some countries, there are cases of black sheeps in banks who has revealed client account information and balance information to these syndicates.
    4)Most common is, they have a black sheep as part of telco helpdesk. These helpdesk agents can they retrieve your information and pass to these syndicates.

    So what can you do?
    Never share your information to ANY unreliable sources.
    Have a habit of changing passwords and even mobile numbers.
    Try not to participate in surveys or discount cards

    Most importantly…when you receive calls from funny numbers such as +4065 indicates the caller does not want you to know his real number. Why would a caller wants to hide his number? unless he has a bad motive obviously….

    so if you receive calls from funny numbers,unknown overseas numbers or even private numbers, never answer them. To avoid your frustrations, install call blockers and add these number in so that these calls will automatically be terminated without getting your attention.

    So keep safe friends…

  • i wanted to ask if i called back but immediately hang up before someone answers,will the information in my phone be stolen?

      No your information will not get stolen in such a scenario.
