Caller name display India becomes the default on mobile networks from November 1, 2026. The Department of Telecommunications (DoT) has directed telecom operators to introduce Calling Name Presentation (CNAP) on 4G and 5G networks, so that people who get calls from unsaved numbers will see a name alongside the number, without installing any app.
The change is meant to help people recognise who is calling and be more careful with unknown callers. It is useful, but it also has limits. Here is how it works, who it covers and how to stay safe.

What Is CNAP?
CNAP is a network service that lets the person receiving a call see information about the caller. In India, it will show the caller's name next to their phone number on 4G and 5G networks. The idea was introduced as a built-in alternative to caller identification apps such as Truecaller.
How Will Caller Name Display Work?
- Saved contacts: if the caller's number is in your contact list, you will see the name you saved first.
- Unsaved numbers: you will see the number along with the name recorded by the caller's telecom operator, which comes from the caller's KYC (Know Your Customer) details.
- Privacy limits: callers who have used the existing calling line identification restriction (CLIR) facility will not have their names displayed. Operators must also design the service so that the caller's name is not stored by the system after the call ends.
- Businesses: separate provisions allow businesses and bulk subscribers who want a preferred name to be shown, with checks to make sure the name is backed by verified registration records.
Why Is the Government Doing This?
India has seen many frauds that begin with a phone call, including fake bank, courier and customer-care calls. Showing a registered name is meant to help people judge unknown callers more easily and to reduce fraud. TRAI agreed in October 2025 that the service should be available by default, instead of only on request, and the DoT's rollout deadline was later fixed for November 1, 2026.
Telecom companies have been preparing their systems. Reports say Airtel and Vodafone Idea partnered with Nokia to deploy the technology they need, while Jio, which runs only 4G and 5G networks, built its own system.
What CNAP Cannot Do
- It does not block spam or scam calls. It only shows more information about the caller.
- A name is not a guarantee of safety. The name shows who the SIM is registered to. A call from a real-looking name can still be a scam, for example if a SIM was obtained with someone else's details or the caller is pretending to be an official.
- It does not cover everyone yet. The first phase covers 4G and 5G mobile networks. 2G, 3G and landline networks will be considered separately.
- Rollout may be uneven. It may take time before every operator, region and phone model shows names correctly.
What You Should Do
- Nothing to activate: operators must offer the service by default. If you do not see names after November 1, ask your operator.
- Keep saving contacts: your own saved name is shown first, so keep your contact list up to date.
- Treat names as one clue: never share your OTP, UPI PIN, card details or passwords with any caller, even if a trusted-looking name appears.
- Call back on official numbers: if a caller claims to be from your bank or a courier company, hang up and call the official number from the company's website or your card.
- Report fraud quickly: if you lose money, call your bank, then the National Cyber Crime Helpline 1930, and file a complaint on cybercrime.gov.in. You can also report suspected fraudulent calls on the government's Sanchar Saathi portal.

What to Watch Next
- How accurate and consistent the displayed names are across operators and phone models.
- Whether the service will be extended to 2G, 3G and landline calls.
- How businesses get verified names displayed, and whether this helps reduce spam from unregistered senders.
- Whether scammers find new ways to get around the system, and how quickly regulators respond.
