TrueCaller : Find Contact Details of Unknown Phone Numbers

TrueCaller : Find Contact Details of Unknown Phone Numbers

Years back I talked about services which let you trace mobile numbers, and those services were not very effective, as you could get only few details like which telecom circle mobile number belongs to. Whenever I get a call from an unknown number, I try to find all the details of the number before calling back. Especially, from a list of missed calls from unknown number. One major benefit of this is, I can figure out the caller details, and if it’s a telemarketing call, I don’t need to call back. TrueCaller is one very popular service, which let you find the details of unknown mobile numbers. Best part is, TrueCaller is also available online, and they have mobile apps for all popular mobile OS platform.

Truecaller Reverse number look up

How Does Truecaller App works?

TrueCaller is a global dynamic directory for mobile phones. It uses the phone directory of users (who have installed TrueCaller) to build the database of mobile numbers, and any user can do number lookup or Name lookup using it. Before, I share more features of TrueCaller, let’s have a look at this intro video, which explain how TrueCaller service works:

Here are some of the benefits/features of using TrueCaller app:

  • You can do a complete free reverse number look up. That means, if you have a mobile number, you can use True caller to find the contact details of that number.
  • You can use Truelcaller to sync with your phonebook. This will help you to update missing information like pictures, address and other details which are available on TrueCaller database.
  • You can block known spam calls, and specially calls from telemarketing companies.
  • You can find contact details of any person, but this service is paid and you need to buy True-caller credits.
  • TrueCaller mobile app is available for all popular mobile platform. Apple, Android, Windows phone, Blackberry, Nokia S60, Nokia S40. You can find the download links here.
  • You can also use TrueCaller online by going to their official website here.
  • It’s available for all the countries.

Why you should use TrueCaller:

TrueCaller is a free service, and it will help you to identify unknown mobile numbers. From business perspective, you can always find details about the caller, which will save a lot of time. Also, if you are getting too many unwanted calls, marketing calls, or calls from bank executives offering free loans, TrueCaller will be a true life saver.

Treucaller app

None the less, it will let you find the details about unknown mobile numbers, so when you get a missed call from unknown number, you don’t have to call back immediately. You can use Truecaller to find details about that number, and if it has bad spam score, you can avoid calling back. Think of True caller as mobile number caller ID.

Also when you install Truecaller app on your mobile phone, you can update your details, which will help to build a better profile of yours on TrueCaller database. That includes adding your photo, details like Twitter handle, Website address, Facebook contacts. It’s up to you, how much details you want to add. Also, even if you don’t want to use this app, I would recommend you to go to their official site, and check what details they have about your mobile numbers. In case if you don’t want true caller to show your identity, you can remove your number from TrueCaller service. You need to add a request here for unlisting your number.

Do you use TrueCaller? What are the benefits you are getting after using it? Do you know any other alternate of TrueCaller service?

    No doubt, truecaller is a great application and I am using it from the last around six months. One problem that I have observes is its inaccuracy in showing wrong locations for a group of numbers. Most importantly, you get to see these numbers mentioned as from Andhra even when the caller has it registered in Delhi. I hope and wish that they improve on this part.

  • Ashok

    is there any alternative of truecaller?

  • Jey

    Hi Harsh, I will not recommend that people to install such a dangerous app. Because it keep on updating our contacts details from our mobile phone. how ever it used to find some unknown numbers. some guys are search some random number in true caller if the number owner names comes as girls they will call their number and send msgs in whatsup etc. pls keep safe don’t install this app. If you want to know the details regards unknown number just go to turecaller website and check.

  • Rahul Rai

    Initially i am able to access this app on Android devices but currently give some critical issue on Blackberry phone. Any Idea Harsh @ Truecaller

  • Harpal Singh

    I think its an awesome tool for all including businessmen and others. I remember my friend got a miss call from a no thrice. After few minutes he called at same no, which took his all prepaid balance off. Really great tool.

  • sudhakar Kalyanam

    I too used. Wonderful app. Thrilling one. It simply displays the name of the person on whose name the mobile number was added to some one’s contact book in mobile…

  • Prasad

    Really an effective tool to find out the prank calls and un wanted calls. Thanks for the great post.

  • Nilantha Jayawardhana

    Truecaller is the world’s largest verified mobile phone community dedicated to helping you take the right call through Caller ID and number search. Great app.

  • achin verma

  • fady

    plz help me what must i do

  • xyz

    What if someone will add someone’s number in unlist category? without intimation to him/her?

  • Vivek Yadav

    Hey Harsh , as you post this the syrian electronic army hacked True Callers database & millions of phone records are stolen and this is confirmed by Truecaller people itself , so even though it helps you find people but we all are giving our details to a single entity , which can be hacked and personal details stolen again and again and so imho it’s a bit dangerous !

    • Harsh Agrawal

      Funny story here is, Truecaller was using an outdated version of WordPress (3.5.1), and that’s why they got hacked.. Good thing is, they don’t store any username and password… Hacking happens at every level, and it happened with Dropbox, Evernote in the past…. I hope they will take corrective measures for future.. < Source>

      • Nisha Pandey

        You are correct Harsh. Pros and cons is indeed everywhere. Just, we have to take care for the same. By the way great app Harsh. Thanks for sharing it.

  • Daniel

    Every time i want to buy credits for true caller it tells me to try again later. Is there any other way to buy the credits?

    Thanks for sharing the article, it gives a very good insight about the philosophy and working of truecaller.

  • Arunkumar Nagappan

    Truecaller App really great to find unknown phone number contact details. Thank you.

  • Kareem

    It is showing name correctly but operator is wrong……..

  • Tahir Siddiqui

    TrueCaller’s concept is great but it’s not good from the security point of you as When you install TrueCaller, it archives your entire phone-book (names and numbers) to its servers. As more and more people install it,
    their database becomes keeps
    getting richer. So there is no privacy! Fortunately Truecaller has the option to unlist your number.

  • Dhruv Bhagat

    If you are having an Android phone too, then you will be amazed with one more feature!

    If any unknown person calls you, then automatically his/her name is displayed within a second while your phone is still ringing.. I was stunned to see this feature in my friend’s Android phone..

    BTW, in iPhone, we can only search unknown number by going to the app!


    • Harsh Agrawal

      That’s one feature I miss on my iPhone. Earlier I had one Cydia App installed call Who’s calling..Which does this job, but I couldn’t find it anymore. Thanks for valuable addition. :)

    • Abhijit Bangal

      I a bit disagree on this. I also have an Android phone. But when I once got a call from an unkonwn number, it didn’t show the name of that person. Instead, it only kept ‘searching…’. I finally remove the app :(

  • shyantan deb

    hey harsh…!!!
    i had used this app in my android phone and after using this app i really get amazed to see that it not only tell the location of the no but also the name of the user. the name comes out is the name of the person who uses the phone not the name of the persone who had registered the SIM card.

    • Harsh Agrawal

      That’s true because this app uses the phone directory of users to fetch the name.

  • Amandeep Singh

    Great app, Harsh…

    I just used it to check my number and bingo, it showed the correct one… I am just wondering how is this app not having people shouting over privacy issues?


  • Gaurav

    Dats my number :P
