Sweden-based caller ID app Truecaller announced it has reached the milestone of 500 million monthly active users. The company reported surpassing 150 million users outside of India, which remains its largest market with over 350 million monthly users.
Truecaller stated it gained 50 million users in 2025, doubling its user base over the past five years. In April 2025, the company reported having over 450 million users. Additionally, more than 4 million users subscribe to its paid plans.
“More and more people need help navigating spam, scams, and unwanted communication every day,” said Truecaller CEO Rishit Jhunjhunwala. “Reaching 500 million users shows the scale of that need and the trust people place in Truecaller to help make communication safer.”
“Our commitment remains focused on continuously strengthening Truecaller with smarter technology and new capabilities that protect users before, during, and after every call or message. Ultimately, our aim is to build a safer, more trusted communication ecosystem for everyone. We now have our sights set on the next milestone: 1 billion users,” he added.
Truecaller has also been expanding its services beyond caller ID. The company recently introduced a feature allowing an admin to end calls on behalf of family members to prevent scams. It has been experimenting with AI for screening and answering calls.
Last month, Truecaller told TechCrunch it is testing AI to automatically monitor disconnected calls when certain scam-related keywords are detected, such as “digital arrest,” where impostors pretend to be law enforcement.
In India, the company faces challenges from the country’s Caller Name Presentation (CNAP) system, which shows the caller’s name as registered with their phone network.
