Truecaller, the prominent caller ID service, has publicly challenged India’s telecom regulator, the Telecom Regulatory Authority of India (TRAI), over rules affecting spam call classification. CEO Rishit Jhunjhunwala criticized TRAI for restricting Truecaller from labeling numbers within India’s designated 1400 and 1600 series as spam. These number ranges were set aside in 2024 for commercial use, with 1400 used by telemarketers and 1600 for service or transaction calls, intending to enhance consumer trust and reduce spam.

Despite the regulatory intentions, Truecaller reports unintended consequences from the anti-spam framework. The company’s data shows users increasingly ignoring and blocking calls from these official business number ranges—81% of 1400 series and 79% of 1600 series calls were ignored in recent months. Blocking actions have surged, with 74 million calls from these series manually blocked and daily blocking of 1600 numbers tripling since late 2025. Unable to tag these calls directly as spam due to TRAI’s restrictions, Truecaller instead added a “Frequently Blocked” tag to inform users.

This dispute follows reports that TRAI sought expanded authority to penalize caller ID apps under India’s Information Technology Act for marking official numbers as spam. Truecaller’s CEO urged regulators to rely on evidence and focus enforcement on actual bad actors rather than apps that aim to protect consumers from nuisance calls. Truecaller emphasized India as its core market, with over 350 million monthly active users there among its global 500 million.

The controversy emerges amid broader pressures on Truecaller as it diversifies beyond caller ID services into new products, including eSIM offerings and scam call blocking features. As regulatory scrutiny and competition intensify, maintaining user trust and compliance in India remains crucial for the company’s growth strategy. Both TRAI and the Ministry of Electronics and Information Technology are yet to comment on the ongoing conflict publicly.
