Caller ID app Truecaller said on Thursday that it crossed the 450 million user mark earlier this week. The company said that it added 50 million users in the past 10 months and 15.5 million users since the beginning of 2025.

India is the company’s biggest user base, so it wasn’t surprising to see Truecaller promoting its Chief Product Officer and MD of India operations, Rishit Jhunjhunwala, to CEO after the company’s co-founders decided to step back from day-to-day operations last year.

Jhunjhunwala said that while India remains a critical market for Truecaller, the company also saw growth in other regions.

“We are proud that we now serve more than 450 million users globally. As before, we continue to see steady growth in our largest market, India, but the fastest relative growth is in markets outside of India. So far in 2025, we see strong growth trends in Latin America, South Africa, Kenya, Nigeria, Malaysia and the U.S., to mention a few markets,” he wrote in a blog post.

However, Truecaller’s prospects in India might be hindered. The country’s telecom department is pushing mobile carriers to implement their own caller ID systems, which could rival the Sweden-based company’s product.

Truecaller said throughout Q4 2024, it maintained an active user base of nearly 430 million users. The company reported positive results for the quarter ended December 2024, with net sales up 23% and profit after tax up 29% from a year earlier. The company’s stock is up more than 33% since the beginning of this year.

Earlier this year, the company updated its app to work better with iOS. Before that update, because of operating system level restrictions from Apple, Truecaller’s live caller ID feature wasn’t on par with its Android version.

Truecaller has also tried to diversify its offerings with products like call recording and transcription, as well as an AI-powered assistant for call screening. It has also been trying to improve its SMS and chat client.
