India to get its Truecaller like called ID system CNAP: What is it and how it works

The Telecom Regulatory Authority of India (TRAI) has approved the implementation of Calling Name Presentation (CNAP), a network-based caller identification system that will display the verified name of callers directly from telecom KYC records. Currently being tested by operators in select regions, CNAP is slated for a nationwide rollout by March 31, 2026. The system aims to enhance transparency, curb spam and scam calls, and reduce reliance on third-party apps like Truecaller, which often depend on inaccurate, crowdsourced data.

What is CNAP, and how will it work?

Unlike current caller ID services that show only phone numbers, CNAP will fetch the caller’s verified name from telecom databases. When someone makes a call, the recipient’s operator will pull the name from a secure Calling Name (CNAM) database and display it instantly — whether on a smartphone or feature phone. This ensures users see the official name linked to the SIM card, improving trust and call authenticity.

According to TRAI, CNAP will be enabled by default for all users, though individuals will have the choice to opt out by contacting their telecom provider. The system could operate using a centralised database maintained jointly by telecom companies, allowing for faster name lookups and consistent performance across networks.

The move follows extensive Department of Telecommunications (DoT) trials conducted across several Indian cities on 4G and 5G networks. While initial tests revealed the need for certain network upgrades, results confirmed CNAP’s reliability in identifying callers. Once fully integrated, CNAP will eliminate the need for third-party apps and give users an official, verified view of who’s calling, helping them avoid fraudulent or spam numbers.
