Truecaller Launches Web-Based Scam Checker to Combat Multi-Channel Fraud

Truecaller is extending its fraud detection capabilities beyond its core caller ID application by launching Scam Checker, a new web and Android service that operates without requiring an app installation or user login. After more than ten years serving over 500 million users, the Swedish company announced on Sunday that the free tool will allow consumers to verify suspicious phone numbers, links, and messages directly through the open web.

The service is initially rolling out in India before expanding to Latin America, the Middle East, Africa, and Southeast Asia. While Scam Checker provides immediate fraud signals based on Truecaller’s community-driven ScamFeed, access to more granular data—such as the name associated with a specific number—remains exclusive to the company’s existing signed-in platform.

To function, the tool analyzes submitted links by expanding shortened URLs and following redirects to their final destinations, cross-referencing them against Truecaller’s proprietary risk database. Users can also paste entire messages, enabling the system to extract embedded phone numbers or web addresses and surface related community reports.

The launch reflects a strategic pivot as scams have evolved from voice calls to encompass text messages, messaging apps, and web links. According to a 2025 GSMA survey of Indian adults, 46% of scam victims reported being approached via messaging apps, compared to 37% through SMS and 32% via voice calls. Truecaller estimates that users conduct approximately 14 million web searches monthly to verify suspicious contacts, a behavior that influenced the development of Scam Checker.

“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?’” said CEO Rishit Jhunjhunwala. “What people do in that moment is search.”

Community intelligence remains central to Truecaller’s operations. The company reports that ScamFeed hosts roughly 20,000 live scam reports in India, with about 1,300 new entries added weekly. During a single week in mid-September, Truecaller evaluated 12.9 billion messages globally and flagged 20.3 million as fraudulent.

This expansion comes as Truecaller faces increasing pressure in India, its largest market with over 350 million users. Telecom operators are introducing government-backed Caller Name Presentation services, while Apple and Google have integrated their own spam-protection features. Additionally, India’s telecom regulator recently mandated that caller ID apps share spam reports with operators, a requirement Truecaller has criticized as a “one-way exchange.”

Jhunjhunwala noted that while caller ID remains the primary entry point for most users, the threat landscape has shifted. “Caller ID was the first problem we solved, and it’s still how most people find us,” he explained. “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.”

The company plans to broaden the types of scams detected by Scam Checker in the near future and intends to introduce screenshot upload capabilities for deeper analysis. The tool also serves as a potential lead generator for Truecaller’s app and enhances the fraud and risk products offered to enterprise clients through Truecaller for Business.
