Truecaller launches sign-in-free web Scam Checker for links, numbers and messages

What launched

Truecaller has released Scam Checker, a free service on the web and Android that lets anyone check whether a phone number, link or message is fraudulent without installing an app or creating an account. According to TechCrunch, the Swedish company launched the tool on Sunday, and it is initially available in India, with expansion planned for Latin America, the Middle East and Africa, and Southeast Asia.

The tool is deliberately lightweight: paste in whatever looks suspicious and get community-sourced reports back. Richer lookups — such as the name tied to a phone number — still require signing into Truecaller's existing service, which positions Scam Checker partly as a funnel toward the main app. CEO Rishit Jhunjhunwala told TechCrunch the tool is aimed at consumers, though the community data it generates could also feed the fraud and risk products Truecaller sells to businesses through Truecaller for Business.

How the checking works

When a link is submitted, Scam Checker expands shortened URLs and follows redirects to the final destination, then compares that destination against Truecaller's proprietary risk database and other fraud signals. Pasted messages are handled differently: the service extracts any phone number or link from the text and surfaces related reports from ScamFeed, Truecaller's crowdsourced feed where users post and discuss scams. The company says it plans to broaden the types of scams the tool can detect and to add screenshot uploads for further analysis.

The design reflects how people actually encounter scams, Jhunjhunwala told TechCrunch. "When you need it, you're usually somewhere else," he said, pointing to situations like a link arriving on WhatsApp or a parent receiving a message about a traffic fine — in that moment, he said, "What people do is search." Truecaller estimates people make roughly 14 million web searches a month to verify suspicious links and phone numbers, based on its analysis of search volumes and traffic to existing verification services.

The community data behind it

ScamFeed is becoming a central piece of Truecaller's detection effort. The company told TechCrunch that around 20,000 scam reports are live on the feed in India, with about 1,300 new reports added each week. Between September 14 and 20, it says it evaluated 12.9 billion messages globally and flagged 20.3 million as fraudulent.

The timing tracks where scams have moved. In a 2025 GSMA survey of Indian adults cited by TechCrunch, 46% of respondents who reported being scammed said they were approached through messaging apps, versus 37% via SMS and 32% via voice calls.

Pressure on the core caller ID business

The push beyond caller ID also comes as Truecaller's original business faces new pressures in India, its largest market with more than 350 million users. Telecom operators there 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. India's telecom regulator last week also ordered caller-ID apps to share user-submitted spam reports with operators — a move Truecaller criticized as a "one-way exchange," according to TechCrunch.

Jhunjhunwala framed the new tool as following the scammers rather than defending old ground. Caller ID was the first problem the company solved and remains how most people find it, he said, but scams have shifted to a multi-channel pattern spanning links, messages and, increasingly, voice and video — so "our protection has to follow the scammer."

Why it matters

Truecaller built its name on identifying incoming callers, but that niche is being squeezed from several directions at once, with carriers and the mobile platforms themselves now offering comparable features. Moving its scam intelligence to the open web — no app, no sign-in — is a bet that the next battleground is the pasted link or forwarded message rather than the incoming call. If Scam Checker takes off, it gives Truecaller two things at once: a low-friction acquisition channel in growth markets such as India, Latin America, Africa and Southeast Asia, and a fresh stream of community reports that sharpens the dataset behind both its consumer tools and its enterprise fraud products. For users, the practical gain is that vetting a suspicious link no longer requires granting an app access to contacts and call logs — though deeper lookups still route back through the signed-in service, which is exactly where Truecaller wants them.
