Truecaller takes scam detection to the open web

Truecaller, the Swedish caller-ID company that serves more than 500 million users, launched Scam Checker on Sunday: a free web and Android service that lets anyone paste in a suspicious phone number, link or message to check whether it’s fraudulent, with no app or sign-in required. The tool expands shortened URLs and follows redirects to a link’s final destination, then checks it against Truecaller’s proprietary risk database and other fraud signals, while also surfacing related reports from ScamFeed, the company’s crowdsourced scam-reporting community. More detailed information, such as the name tied to a phone number, remains available only through Truecaller’s existing app, which requires a sign-in.

The tool is rolling out first in India and is set to expand to Latin America, the Middle East and Africa, and Southeast Asia, the company said. CEO Rishit Jhunjhunwala said Scam Checker was built around the moment people actually encounter a scam — a suspicious link on WhatsApp, a forwarded screenshot — and go looking for a quick way to verify it: “What people do in that moment is search.” Truecaller estimates people run about 14 million web searches a month to check suspicious links and phone numbers, based on its analysis of search volumes and traffic to existing verification services. That lines up with a 2025 GSMA survey of Indian adults, in which 46% of people who reported being scammed said they were approached through messaging apps, 37% via SMS and 32% through voice calls.

Truecaller’s crowdsourced ScamFeed now carries about 20,000 live scam reports in India, with roughly 1,300 new ones added each week; between September 14 and 20, the company said it evaluated 12.9 billion messages globally and flagged 20.3 million as fraudulent. It plans to broaden the scam types Scam Checker can detect and add screenshot uploads. Beyond acting as a lead-generation channel for Truecaller’s app, the community data could also strengthen the fraud and risk products the company sells to enterprises through Truecaller for Business, though Jhunjhunwala said Scam Checker itself is aimed at consumers.

The push beyond caller ID comes as Truecaller’s core business faces new pressure in India, its largest market with more than 350 million users: telecom operators are rolling out the government-backed Calling Name Presentation service, and Apple and Google have added their own caller-ID and spam-protection features. Last week, India’s telecom regulator also ordered caller-ID apps to share user-submitted spam reports with telecom operators — a move Truecaller criticized as a “one-way exchange.” “Caller ID was the first problem we solved, and it’s still how most people find us,” Jhunjhunwala said. “But scams moved to a more multi-channel approach with links and messages, and increasingly to voice and video. Our protection has to follow the scammer.”

Why it matters

As caller ID turns into a shrinking moat — squeezed by carrier- and OS-level competition — Truecaller is betting that scam intelligence, not phone-number lookup, is the more defensible long-term business, with a stated expansion path into Latin America and the Gulf region.
