Truecaller pushes back on India's anti-spam call rules

Truecaller CEO Rishit Jhunjhunwala took to X on Wednesday to publicly challenge the Telecom Regulatory Authority of India (TRAI, the country’s telecom regulator), accusing the watchdog of preventing the company from displaying community-reported spam information on calls from India’s dedicated 1400 and 1600 number series. He said the restriction has enabled abuse of those numbers and eroded trust in legitimate business calls.

The dispute traces back to a framework TRAI introduced in 2024, which designated the 1400 and 1600 series for commercial communications — businesses use 1400 for telemarketing calls and 1600 for service- and transaction-related calls. TRAI mandated migration to the dedicated numbering series, saying the move would help consumers identify legitimate business communications and curb spam and scam calls. The framework arrived amid growing concern over spam and scam calls in India, one of the world’s largest telecom markets. Last year, the country’s communications ministry said authorities had disconnected more than 2.1 million fraudulent mobile numbers and taken action against more than 100,000 entities over the preceding year.

Jhunjhunwala argued the policy has backfired. Citing internal company data, he said Truecaller users ignored 81% of calls from the 1400 series and 79% from the 1600 series over the past eight months, and manually blocked 74 million calls from the two series in that period. Daily blocking actions against 1600-series numbers, he said, have more than tripled since October 2025. Unable to mark the designated numbers as spam directly, Truecaller instead introduced a “Frequently Blocked” badge to flag when a number from the series has been blocked by many users.

The unusually public criticism followed a report from Indian business daily The Economic Times that TRAI had sought powers under India’s Information Technology Act to act against caller ID apps — including Truecaller, Hiya, and Whoscall — for labeling 1400- and 1600-series numbers as spam. TRAI and India’s Ministry of Electronics and Information Technology, which would weigh any such proposal, did not immediately respond to requests for comment. The dispute lands at a sensitive moment for Truecaller: its core caller ID business faces growing regulatory and competitive pressure as the company expands into new products and services, and India remains its largest market by a wide margin, with more than 350 million of its 500 million monthly active users based in the country. Jhunjhunwala said Truecaller would share its data with the IT ministry as part of the regulatory process, arguing that any decision on caller ID apps should be evidence-based. “Penalize the bad actors, not the ones like Truecaller that make a significant positive impact,” he wrote.

Why it matters

A regulator empowered to police how caller ID apps label numbers could reshape how spam-detection tools operate in one of the world’s biggest telecom markets, right as Truecaller leans on that same market for the bulk of its user base.
