Truecaller is basically a mobile application that shows the details of an unknown number when someone calls you. In simple words, by using Truecaller you can find the details of the owner of a particular mobile number.

It is developed by True Software Scandinavia AB in 2009. This app is available for both Android and iOS smartphones.

How does Truecaller Works?

Truecaller uses crowd-sourcing to show users details of any mobile number. So, when someone downloads their app, it takes all the contact information of that user and stores them in their server (or database).

It uses this data to provide users the information about unknown numbers and this process of showing data from collecting it with different users is called Crowd-Sourcing.


After collecting user’s data, they apply their AI (Artificial Intelligence) and Machine Learning to analyze this data and make them appropriate.

On applying AI and Machine Learning, these data also go through data matching, and each mobile number is assigned a Truecaller ID.

So, when someone receives calls from an unknown number or searches for the number on their website or app, the caller ID associated with the number will be displayed to you.
