From 1 November, Unknown Numbers May Show a Name Too: How CNAP Works

A small but useful change has come to your phone. When a call comes from an unknown number, your screen may now show not only the number, but also the name registered to that number. The feature is called CNAP — Calling Name Presentation — and the Department of Telecommunications (DoT) has directed telecom companies to start it from 1 November 2026.

What Is CNAP, in Simple Words?

Until now, people often relied on an app to identify an unknown number, or searched the number manually. With CNAP, the name will come directly from the telecom network. In other words, the name recorded with the company whose SIM the caller is using will appear on your screen along with the number. You do not need to download an app or make a separate request — the feature will be available by default.

What Will You See on Your Screen?

If the number is saved in your contacts, you will see the name you saved. Your saved name will always come first. If the number is not saved and the call is from within India, you will see the name from the caller's operator record. If the call is from outside India and the number is not saved, your screen will show 'International Call', not a person's name. People who have taken the CLIR service to hide their identity will not have their name shown.

Where Will It Be Available First?

In the first phase, CNAP will be available on 4G and newer networks, such as 5G. Whether it is later brought to older 2G, 3G and landline networks will be considered later. That is why it may not appear on every phone or every network at the same time at first — it will be rolled out gradually.

How Will It Help Ordinary People?

The biggest benefit is that it will become a little easier to identify spam and fake calls. When a name appears on the screen, you can decide with information, not guesswork, whether to answer. It will also be easier to recognise genuine calls related to couriers, banks or deliveries. However, one point is important to understand — a name appearing does not guarantee that a call is fully genuine. Fraudsters can sometimes misuse numbers that look genuine, so never share OTPs or bank details on a phone call.

One Small Tip

If the spelling of the name on your SIM is wrong, or an old name is recorded, it is worth getting the record updated with your operator, so that others see your correct name. Business connections may also show their verified brand or trade name, for which the required documents will need to be provided.
