Government starts testing Truecaller-like caller ID: Here’s what CNAP is and how it works

The Indian government has begun testing CNAP, a new caller ID system that shows the Aadhaar-linked name of the caller before your saved contact name. Here’s how CNAP works, why it’s appearing on your phone, and what it means for caller identification, spam control and privacy in India.

If your phone has suddenly started showing unfamiliar names when someone calls you, names you never saved, do not worry. It is not a glitch. It is the Indian government’s new CNAP system being tested in some parts of the country.

CNAP stands for Calling Name Presentation and it works like a government-backed and verified version of Truecaller. The idea is to show you the actual Aadhaar-linked name of the person calling you instead of relying on crowdsourced data or user guesses.

Here is what happens when someone calls you. Your phone first displays the Aadhaar name associated with that mobile number. After a moment, it switches to the name you have saved in your contacts. This means the verified government identity appears first and your personal saved label appears second.

Why is this happening now? The government approved the CNAP portal last month and telecom operators have begun enabling it to make caller identification more accurate and trustworthy. The aim is to reduce spam, prevent fraud and give people more confidence when answering calls from numbers they do not recognise.
