CNAP, or Calling Name Presentation, shows the name of the person calling you on your phone screen, using the name registered with the caller's telecom operator during KYC. It is a network-level service, so you do not need an app.

When does caller name display start in India?

The Department of Telecommunications issued a circular on 13 October 2026 directing all telecom operators to implement CNAP as a default service from 1 November 2026.

Will CNAP work on all phones and networks?

In the first phase, CNAP covers calls on 4G, 5G and newer networks. 2G, 3G and traditional landline networks are excluded at launch, according to reports on the DoT circular.

Can I stop my name from being shown?

Reports say subscribers who have Calling Line Identification Restriction (CLIR) active will remain hidden. No other opt-out has been described. CLIR is typically available to specific categories of users on request.

Does CNAP stop spam and fraud calls?

It helps, because the name shown comes from the operator's verified KYC records rather than crowd-sourced data. But a displayed name does not guarantee that a call is genuine or safe, so you should still never share OTPs or banking details on a call.

Caller Name Display (CNAP) Mandatory From 1 November 2026: How It Works and What Changes, Explained

From 1 November 2026, the name of the person calling you will flash on your screen even if their number is not saved, and it will come straight from your telecom operator, not an app. The Department of Telecommunications (DoT) has ordered every operator to switch on Calling Name Presentation (CNAP) by default. Here is how it works and what it means for you.

The 60-second version

What: The caller's KYC-registered name shows on incoming calls.
From: 1 November 2026, under a DoT circular dated 13 October.
Who: All telecom operators, including Jio, Airtel, Vi and BSNL.
Networks: 4G, 5G and newer at launch. 2G, 3G and landlines excluded.
App needed? No. It works at the network level.
Hide your name? Only users with CLIR active stay hidden, per reports.

How CNAP works

When someone calls you, your operator asks the caller's operator for the name registered against that number during SIM KYC, and shows it on your screen. Reports on the circular describe these rules:

Saved contacts: Your phone still shows the name you saved.
Unsaved Indian numbers: You see the subscriber name from the originating operator's records.
International calls: These carry a standard "International Call" tag.
Businesses: Call centres and telemarketers can show a brand name only after the operator verifies a registered trademark or a trade name verified on the GST portal.

The DoT says the mandate implements Rule 48(1) of the Telecommunications Rules, 2026, following a TRAI recommendation to move CNAP from an opt-in feature to a default service.

What about privacy?

The circular, as reported, includes two protections:

CLIR users stay hidden. Subscribers with Calling Line Identification Restriction active will not have their name displayed.
Zero retention. Operators must use a "security by design" setup that deletes the name lookup data as soon as the call ends.

There is no general opt-out described in the reports. If your SIM is registered in someone else's name, such as a parent or employer, that name is what others will see.

CNAP vs Truecaller

	CNAP	Truecaller-style apps
Source of name	Operator KYC records	Crowd-sourced contact lists
App needed	No	Yes
Can be edited by users	No	Often yes
Default on all phones	Yes, from 1 November (4G/5G)	Only if installed

CNAP's big advantage is that the name is tied to verified identity documents, so it is harder to fake. Truecaller-style apps still offer extra features such as spam reports and call blocking.

Will it end spam and fraud calls?

It should reduce them, because scammers can no longer hide behind a random number with a made-up label. But it is not a guarantee. A fraudster using a SIM issued on someone else's documents will display that person's name. The basic rules still apply:

Never share an OTP, PIN or CVV on a call.
Banks and the government do not ask for passwords over the phone.
Report fraud calls on the Sanchar Saathi portal or the Chakshu facility.

What you should do now

Check whose name your SIM is registered in. If it is outdated, visit your operator's store to update KYC.
Make sure you are on 4G or 5G. CNAP will not work on 2G or 3G calls at launch.
Keep your guard up. A name on the screen is useful information, not proof of trust.
