Truecaller has come up with yet another unique product in the form of TrueSDK, which is aimed at helping third party apps to verify numbers using Truecaller database. The API is expected to fetch the user information from the Truecaller profile and the Truecaller verified numbers.

Third party apps can make use of this information to sign up, update and verify the users phone number. As of now TrueSDK has partnered with some of the popular services including Quickr, MobiKwik, RedBus, CarDekho, OYO Rooms and many more. As far as we understand the TrueSDK works similar to how “Login using Facebook” works on third party apps.


TrueSDK will facilitate complete on-boarding process and will also verify the number, and as of now it is free to use for existing Truecaller users. On the client side, a lightweight SDK will be deployed and this will help them integrate TrueSDK effortlessly.

This is what Priyam Bose, Director of Worldwide Developer Relations at Truecaller had to say,

Phone numbers are quickly becoming the primary personal identity to verify users in the global mobile arena. App Developers are looking for ways to minimize friction in user on boarding and engagement flows. TrueSDK gives developers an opportunity to fulfill these needs and overtime bridge offline and online identity gap. Instead of having every app developer build and maintain their own systems, they can now use TrueSDK and instead focus more on their core aspects of the app led offering

TrueSDK essentially acts like an autofill and users will be able to select the type of information they would be comfortable sharing. Since Truecaller already has 100-Million registered users in India, True SDK can be of great help, especially for the rural folks without active email ID as they can register directly with the phone number. The exponentially growing smartphone market and the very fact that first time Internet users usually come from smartphones will further increase the relevance of TrueSDK. Presumably, the only drawbacks we can see is level of access to our information by the third party apps.
