Sometimes, I receive phone calls from unknown mobile numbers that neither I nor does my cellphone recognize. In such cases I often wished if I could find details (like caller’s name and location) of the phone number. If I happen to miss the call then it becomes a bit difficult decision whether to return the call. The dilemma gets enhanced also because the unknown number could as well be a wrong number and also it could that be of a nagging tele-caller. Very routinely, we all face this problem of unknown phone numbers. In such times, TrueCaller service comes as a great respite. Using TrueCaller, you can easily trace any mobile number and put a name to an unknown mobile phone number number.

Recently, Kari Krishnamurthy, Truecaller’s vice-president of growth & partnerships in Asia, Middle East & Africa, said that “over half of our 70 million users are in India, and we are adding 110,000 users a day here”. So, you can imagine how popular this app is in India.

Trust me, this is extremely useful if someone is trying to harass you by making unsolicited, unwanted and/or blank calls. Faced with such anti-social elements, people often wish if they could find the details of phone number that is being used by the offender. TrueCaller mobile app and website are probably the quickest and best way to determine the ownership of such unknown phone numbers. In this article, I will talk about the features of TrueCaller service, but let’s first understand how this service works.

How to Find Details of Unknown Numbers using TrueCaller

TrueCaller essentially relies on the massive community of mobile phone users. It is arguably the largest of such communities. You can consider it as a huge telephone directory.

If you install TrueCaller app on your mobile phone, the app will pick up contact details from your phonebook and integrate the details in a global database managed by the service. In the same fashion, the app collects information from millions of users. As a result, the database becomes really fat.

So, TrueCaller works on the lines “if your phonebook does not have a number —someone else’s phonebook may have it!”

Isn’t it a simple idea… power of unity?!

This database of mobile phone numbers is freely searchable by anyone through TrueCaller app or through TrueCaller website.

  1. Go to the TrueCaller website
  2. Now you would need to sign-in. The website will give you the following options to do login:
    1. Google account
    2. Microsoft account
    3. Facebook account
    4. Yahoo! account
  3. Enter the phone number for which you want to find the caller details.Website will automatically detect your country and country code. If, by chance, the code is wrong, you can select the country code from the drop-down list.
  4. Click on the Search button.
  5. TrueCaller will wade through the database and show you all the details that it will find for the given phone number. For example, see the following image:
TrueCaller gives you details of a given phone number. It provides name, address, country of the caller.

  9. It doesn’t matter where the caller is located. The TrueCaller directory is global and therefore it can give you details of even the foreign phone numbers.

Let’s now watch the official video introduction of TrueCaller. This YouTube video explains how to install Truecaller, how it works and its main features:

Reasons and Benefits of Using TrueCaller

In today’s chaotic world, you will find lots of reasons as to why you want to use a service like TrueCaller. A friend of mine recently complained that she was getting missed and blank calls from a particular mobile number. The caller was making tens of calls everyday. When my friend picked the call or called back, no one would speak up from the other side! Such harassment!

In the days of fixed line phone, we used to have telephone directories which we could look up after getting the caller’s number from Caller Line Identification Presentation (CLIP) service. These thick paper directories used to have name and address of the fixed line owners. So, it was easy to nab a trouble-maker.

But in the era of mobile phones, we do not have such directories. It is tough to find as to who owns a given mobile number. This presents an ideal playground for those who have nothing better to do than causing problems for others. On top of this, mobile numbers keep on changing hands. As a result probability of getting wrong number calls also increases. Then we have our dear tele-callers who will try to sell us anything from loans to insurance to what not.

TrueCaller is a precious service in such a scenario. It provides you with some degree of control on how to handle unwanted calls. Yes, it uploads your contact book also into its database —but then they keep it safe and also allow you to edit your details. TrueCaller works with the power of masses. Everyone contributes for the benefit of everyone else. If you’re not up to anything mischievous, then you should not worry about your number going into the database of TrueCaller.

A global service of the nature of TrueCaller is very important because tech-savvy harassers can easily guise their phone numbers and make it look as though the call is originating from a foreign country. They can also play a great number of other tricks. TrueCaller empowers us, the common users, by sharing real information about phone numbers.

    Hi Lalit,
    I’m not able to find the reason why any unknown number, who has given me missed call is flashing under contacts. This is when I searched in truecaller.
    There was no call history neither message exchange on this number in past. Only one miss call can make that number to flash under contact?
    Can you please help if you have any information regarding this.

      If Truecaller does not recognize a number, most probably it would be a new number and not stored in the phone books of any of the Truecaller users.

  8. prabakaran says:

    Hello Sri Lalit Kumar, I have a samsung android phone which I rarely use. Most of the time, I keep it switched off. I am having it, since its possession has become mandatory for several government transactions. Also, as an old man (80 years plus) I don’t move about frequently and so mobile phone is superfluous for me. My landline is more than enough for me. However, when I do keep it on, I get a sizable number of calls, whose origin I do not know. Can you kindly suggest to me as to how I can download the ‘truecaller’ app on my PC using windows 10 OS. I would be obliged for a reply through email.

  16. wisdom says:

    Truecaller is good but the only problem I normally have with them is that without internet connection you cannot get the caller names and his or her details. Moreover this time the network providers are too increasing their connectivity especially MTN Ghana.
