Truecaller Caller ID is already used by 450 million users

Truecaller, a phone number identification app from Swedish company True Software Scandinavia AB, already has over 450 million monthly active users. The number of users has increased by 15.5 million since the beginning of 2025, and by 50 million in the last ten months.

Turecaller's main market is India, where the mobile app is most popular, but the main growth is coming from other regions. The company is seeing significant growth in Latin America, South Africa, Kenya, Nigeria, Malaysia, and the US, among other countries.

Truecaller reported an average monthly active user base of 429.4 million in Q4 2024. By the end of the quarter, that figure had grown to 434.5 million, and now to 450 million.

"What started off as a quite basic Caller-ID has over the years transformed to become a loved communication platform that solves for many different communication needs. We are proud that we now serve more than 450 million users globally," says CEO Rishit Jhunjhunwala. "We continue to develop safe communication that goes way beyond just a caller-ID and we constantly add new functionality to protect our users before, during, and after a phone call or SMS."

In January 2025, Truecaller gained real-time number identification on the iPhone after the Live Caller ID Lookup feature was introduced in iOS 18. In addition to caller ID, the app, which is also available on Android, offers spam and scam blocking for both calls and SMS, business identification, number lookup, and more.
