A DoT circular dated 13 October 2026 makes operators show callers' KYC-registered names on 4G and 5G phones from 1 November 2026.
What Happened
From 1 November 2026, mobile phones in India will show the registered name of the person calling, taken from the telecom operator's own customer records, under an order from the Department of Telecommunications (DoT). A DoT circular dated 13 October 2026 directs all telecom service providers to switch on the Calling Name Presentation (CNAP) service by that date on 4G and newer networks, including 5G, after operators completed trials. The name shown will be the one linked to the caller's SIM through Know Your Customer (KYC) checks, not a crowdsourced label of the kind used by caller-ID apps. Rollout on 2G and 3G networks and on landlines will be considered separately.
Key Facts
- The DoT has directed telecom operators to implement Calling Name Presentation (CNAP) by 1 November 2026.
- The order applies to 4G and higher-generation networks; 2G, 3G and fixed-line networks will be examined separately.
- The displayed name comes from the operator's KYC subscriber records, not from crowdsourced data.
- If the caller is saved in the recipient's contacts, the saved name appears first, followed by the operator-identified name, according to reports of the circular.
- Subscribers who have opted for Calling Line Identification Restriction (CLIR), which hides their number, will remain hidden.
- The DoT has said CNAP does not guarantee that a caller is genuine and will not by itself stop spam, impersonation or fraud.
- The idea was first put out for consultation by the Telecom Regulatory Authority of India (TRAI) in 2022, and TRAI recommended a CNAP service in 2023.
Why It Matters
Calls from unknown numbers are part of daily life for most phone users, including students and young job seekers, and some of them are scams: fake job offers, loan and investment pitches, and callers posing as officials. Until now, the main way to see who was calling from an unknown number was a third-party app, which identifies callers based on how other users have saved the number. Those labels can be wrong or easy to manipulate, a weakness TRAI pointed out when it first consulted on the idea.
CNAP changes the source of the name. Because it comes from the KYC details the caller gave when buying the SIM, it is tied to an identity document rather than to guesswork. For someone receiving a call from an unfamiliar number, seeing a real registered name, or seeing a name that does not match the caller's claim, is a useful warning sign before picking up or sharing any information.
It is not a cure-all, and the DoT itself has said so. A SIM registered in one person's name can be used by someone else, names in the KYC records can be incomplete, and scams that arrive over internet calling apps or messaging platforms will not be covered by a service that works on the mobile network. The rule is best seen as one more layer of protection, not a reason to trust any caller whose name appears on screen.
| Point | What the order says |
|---|---|
| Start date | 1 November 2026 |
| Networks covered | 4G and 5G |
| Source of name | Operator's KYC records |
| Hidden numbers (CLIR) | Stay hidden |
| 2G, 3G, landlines | To be considered separately |
Impact
Short-term: From November, most smartphone users on 4G or 5G will start seeing names for unknown callers without installing any app. People should check that their own SIM is registered correctly in their name, since that is the name others will see when they call.
Long-term: If the service works well, it could reduce reliance on caller-ID apps that upload users' contact lists, and make it harder for fraudsters to hide behind unknown numbers. Its success will depend on how accurate operators' KYC records are, and on how quickly the government extends it to older networks.
Who is affected: All mobile subscribers on 4G and 5G networks; students and young job seekers who receive calls from unknown numbers; businesses that call customers; caller-ID app companies; and telecom operators, who must build and run the service.
Key Takeaway
From 1 November 2026, Indian 4G and 5G phones will show callers' KYC-registered names by default, a useful anti-scam signal that the DoT says is not a guarantee of who is really calling.
Questions and Answers
What is CNAP caller ID and when does it start in India?
Calling Name Presentation (CNAP) shows the registered name of a caller on the recipient's phone, taken from the telecom operator's KYC records. The DoT has told operators to implement it by 1 November 2026 on 4G and 5G networks.
Will I need to install an app or change settings?
The service runs on the telecom network itself, so no app is needed. Reports of the order say it will be available by default on 4G and newer networks.
Will CNAP stop spam and fraud calls?
Not on its own. The DoT has said the name display is not a guarantee of authenticity and will not by itself stop spam, impersonation or fraud. It gives users more information before they answer.
Can I hide my name from others?
Subscribers who have opted for Calling Line Identification Restriction, which hides their number, will remain hidden, according to reports on the rules.
