Truecaller Opens Its Scam Intelligence to the Web, No App Required

Truecaller is taking more than a decade of scam intelligence built from a caller ID business serving over 500 million users and putting it on the open web — no app, no sign-in required.

The Swedish company on Sunday launched Scam Checker, a free web and Android service that lets users paste a suspicious phone number, link, or message to find out whether it is fraudulent. The tool surfaces related reports from Truecaller's community feed, ScamFeed. More detailed information about a phone number, including the name associated with it, still requires signing in through Truecaller's existing service.

The tool launches first in India, with expansion planned to Latin America, the Middle East and Africa, and Southeast Asia, the company said.

How it works. Scam Checker examines the link a user submits, expanding shortened URLs and following redirects to the final destination. It then checks the result against Truecaller's proprietary risk database and other fraud signals. Users can also paste a suspicious message, and the service picks out any phone number or link and surfaces related community reports.

The product was shaped by search behavior. Truecaller estimates people make 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.

"When you need it, you're usually somewhere else. The link shows up on WhatsApp. Your mum gets a message about a traffic fine. A friend forwards you a screenshot and asks, 'Is this real?'" CEO Rishit Jhunjhunwala told TechCrunch. "What people do in that moment is search."

The community engine. Truecaller's crowdsourced reporting has become central to its scam-detection effort. About 20,000 scam reports are live on ScamFeed in India, with roughly 1,300 new reports added each week, the company told TechCrunch. Between September 14 and 20, Truecaller evaluated 12.9 billion messages globally and flagged 20.3 million as fraudulent.

Scam Checker is aimed at consumers, but the free tool doubles as lead generation for Truecaller's app. The community reports also sharpen the company's view of scams circulating at any given time, which could strengthen its fraud and risk products sold to enterprises through Truecaller for Business, although Jhunjhunwala said Scam Checker itself targets consumers.

Scams have moved. The launch reflects how fraud has spread well beyond phone calls. In a 2025 GSMA survey of Indian adults, 46% of those who reported being scammed said they were approached through messaging apps, 37% via SMS, and 32% through voice calls.

In the near future, Truecaller plans to broaden the types of scams Scam Checker can detect and add screenshot uploads for further analysis.

Pressure at home. The pivot beyond caller ID comes as Truecaller's core business faces new pressures in India, its largest market with more than 350 million users. Telecom operators are rolling out the federal government-backed Calling Name Presentation service, while Apple and Google have built their own caller identification and spam-protection features into phones.

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."

Jhunjhunwala frames the shift as following the scammers rather than fleeing competition.

"Caller ID was the first problem we solved, and it's still how most people find us," he 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."

With Scam Checker expanding across emerging markets and enterprise fraud products on the other side of the business, Truecaller is betting that its community data — not its original caller ID feature — becomes the asset carriers and platforms can't easily replicate.
