Caller name on your screen: what CNAP proves, and what it can't

From 1 November 2026, an unsaved number calling you on 4G or 5G should show a name: the one the caller's SIM is registered in. That helps. It does not tell you who is holding the phone.

What changed

The Department of Telecommunications issued a circular dated 13 October 2026 asking telecom operators to switch on Calling Name Presentation (CNAP) by default for users on 4G and newer networks, including 5G, from 1 November 2026. MediaNama and Business Today reported the circular on 15 and 16 October 2026; the summary below follows their reporting.

  • Default, no request needed: operators must provide the service without users asking for it. MediaNama reports that TRAI had recommended an opt-out in October 2025 and that the final circular does not include one.
  • Where the name comes from: each operator keeps a database linking numbers to the subscriber names collected at SIM verification (KYC). During an incoming call, the receiving operator looks the name up.
  • What you see: a contact you have saved still shows your saved name. An unsaved Indian number shows the registered name. An international call shows "International Call".
  • Businesses: companies using bulk connections can show a preferred name instead, but only a registered trademark or a trade name registered on the GST portal, verified by the operator.
  • Not yet covered: 2G, 3G and landline networks are to be considered separately.

What the name proves, and what it can't

CNAP answers one question well: in whose name is this SIM registered? Investigators have asked that question for years through legal process. Now everyone sees a version of it on the call screen.

  • It is the SIM owner, not the speaker. Fraud networks routinely use SIMs registered to other people, often bought or rented in someone else's name. A real person's name on the screen can sit on top of a scam call.
  • It is a telecom service. Calls placed through WhatsApp and other internet apps are not ordinary network calls, so the network's caller name does not apply to them. Many digital-arrest and fake-officer calls arrive on exactly those apps.
  • A name can be withheld. Operators must still offer calling line identification restriction (CLIR). MediaNama reports that since 2015 it has been limited to VIPs and government officials, and to others on a senior police officer's recommendation.
  • Handsets vary. The reported circular says nothing about phones, so whether every handset displays the name is not yet clear.

A name on the screen is a clue, not an identity.

What to do when the caller says they are a bank or the police

  1. Treat the name as one data point. A mismatch — a "bank" call showing a person's name — is a strong warning. A match proves nothing on its own.
  2. Hang up and call back. Use the number printed on your card, the bank's app or the official website, never a number the caller gives you.
  3. No officer arrests you on a call. There is no such thing as a digital arrest. No police, CBI, customs or court official will ask you to stay on a video call or move money to clear your name.
  4. Report the number. Report suspected fraud calls and messages on Sanchar Saathi through the Chakshu facility. If money has moved, call 1930 or file at cybercrime.gov.in the same day.
  5. Check your own name. If a call ever shows your name for a number you do not own, a SIM may have been issued on your documents. Sanchar Saathi lets you see the mobile connections registered in your name and report the ones that are not yours.

Questions people ask

What is CNAP in India?

Calling Name Presentation: a telecom service that shows the name a calling number is registered in, taken from the operator's subscriber (KYC) records. The DoT circular of 13 October 2026, as reported, makes it default for 4G and 5G users from 1 November 2026.

Can I turn off CNAP?

As reported by MediaNama, the circular has no opt-out for receiving names. Callers can withhold their name only through calling line identification restriction (CLIR), which is restricted to a limited set of users.

If the screen shows a real name, is the call safe?

No. CNAP shows the name the SIM is registered in, not who is speaking, and scam networks use SIMs registered to other people. Calls on WhatsApp and other apps do not use CNAP at all. Hang up and call back on an official number.
