TRAI regulation of Truecaller

TRAI mandate requires caller ID apps to whitelist 140- and 160-series numbers used for promotional and banking calls, preventing them from being flagged as spam.
Truecaller reports that whitelisting these series has led to over 51 million unanswered calls daily and increased spam volume.
Truecaller introduced a 'Frequently Blocked' badge to identify spam even on whitelisted numbers, leading to friction with TRAI.
TRAI has reportedly approached the Ministry of Electronics and Information Technology (MeitY) to seek authority to regulate caller ID apps.
The Telecom Commercial Communications Customer Preference (Second Amendment) Regulations, 2025, aimed to tighten norms against unsolicited commercial communications (UCC) and curb misuse of 10-digit numbers.
Government bodies (DoT, MeitY, TRAI) are increasingly intervening in the platform design of private communication services, including SIM-binding requirements and restrictions on username features.
