Short answer
Truecaller, after more than a decade building its caller ID business, is opening up the scam intelligence it gathered along the way through a web tool that needs no app or account. Users can paste a suspicious number, link or message and get results drawn from community reports. The move responds to scams shifting from phone calls to messaging apps.
Highlights
- Truecaller announced Scam Checker, a sign-in-free web tool built on data from its more than 500 million users; it will launch first in India, then expand to Latin America, the Middle East and Africa, and Southeast Asia.
- The company said it evaluated 12.9 billion messages globally between September 14 and 20, flagging 20.3 million of them as fraudulent.
- A GSMA survey found that 46% of scammed users were targeted through messaging apps, 37% through SMS and 32% through voice calls.

Truecaller, which has spent more than a decade building its caller ID business, is now taking the scam intelligence it gathered along the way beyond its own app. According to TechCrunch, the company launched Scam Checker on Sunday, a web and Android tool that requires no app download or sign-in.
How does Scam Checker work?
Users paste a suspicious phone number, link or full message into the tool, which expands shortened links and follows redirects before checking them against Truecaller's own risk database and its community-sourced ScamFeed reports. More detailed information, such as the name tied to a number, remains available only through the main app, which requires sign-in. The tool is launching first in India, then expanding to Latin America, the Middle East and Africa, and Southeast Asia.
Why is the company moving beyond caller ID?
Truecaller CEO Rishit Jhunjhunwala says scams no longer stay on a single channel: a link shows up on WhatsApp, or someone is asked whether a forwarded message is real. The company estimates users make about 14 million web searches a month to verify suspicious numbers and links, a behaviour that shaped Scam Checker's launch. Truecaller's ScamFeed community has around 20,000 live scam reports in India, with roughly 1,300 new reports added each week. Between September 14 and 20, the company evaluated 12.9 billion messages globally and flagged 20.3 million of them as fraudulent.
Why is channel diversity growing?
According to a 2025 GSMA survey conducted in India, 46% of scammed users were approached through messaging apps, 37% through SMS and 32% through voice calls. Competition is also intensifying in Truecaller's largest market, India, where it has more than 350 million users: telecom operators are rolling out the government-backed Calling Name Presentation service, while Apple and Google have added their own caller ID and spam-protection features. India's telecom regulator last week ordered caller-ID apps to share user-submitted spam reports with operators, a move Truecaller criticised as a 'one-way exchange'.
Frequently asked
