India requires call identification apps to return spam reports to operators

The Indian regulator requires Truecaller and its competitors to feed a blockchain platform managed by telecom operators. The company denounces a one-way exchange.

The Indian Telecommunications Regulatory Authority (TRAI) has changed its rules on Friday: call identification and filtering applications must now transmit spam reports from their users to a blockchain-backed platform operated by the country's telecom operators. Companies are also required to report in advance any use of automated or AI-driven call systems.

Truecaller is the first target: the application claims over 350 million users in India, a market where subscribers received approximately 42 billion unwanted calls in 2025, of which nearly 12 billion were blocked by it. The planned rate for business calls to private individuals is up to 5 per minute, or about 0.052 cents of dollars.

The Swedish publisher challenges the device, which it describes as unilateral and anti-competitive: it must deliver the data patiently collected from its user base without obtaining equivalent matching from the operators.
