The Government of India has made it mandatory for telecom service providers to introduce a caller name identification system from November 1, 2026, in a move aimed at helping mobile users identify unknown callers. Under the new directive, incoming calls will display the caller’s name alongside their phone number, even if the number is not saved in the recipient’s contact list.
The Department of Telecommunications (DoT) issued the directive on October 13, instructing telecom operators to roll out the Calling Name Presentation (CNAP) service across their service areas. The facility will be provided to subscribers without requiring them to make a separate request. The initial rollout will cover wireless networks using 4G and newer technologies, including 5G.
How will the new caller name identification system work?
The CNAP service will display the caller’s name using subscriber information maintained by the originating telecom service provider. The recipient’s phone screen will show the caller’s number along with the corresponding name.
If the incoming number is already saved in the recipient’s contact list, the saved contact name will appear. For unsaved domestic numbers, the name recorded in the caller’s telecom subscriber records will be displayed. Calls originating internationally will be identified with the label “International Call” when the number is not saved in the recipient’s contacts.
Unlike third-party caller identification applications, the new facility will operate through telecom networks and rely on subscriber records maintained by service providers.
Why is the government introducing CNAP?
The introduction of CNAP is expected to make it easier for users to identify unfamiliar callers before answering their phones. It could also help people make more informed decisions when receiving unexpected calls, including those that may be associated with spam, telemarketing or fraud.
However, displaying a caller’s registered name does not automatically establish that a call is genuine or safe. Users should continue to exercise caution when receiving calls asking for banking details, passwords, one-time passwords (OTPs) or other sensitive information.
Will CNAP work on all mobile phones?
The first phase of the rollout will cover wireless telecom networks using 4G and higher-generation technologies. The government has said that the introduction of the service on 2G and 3G networks, as well as traditional landline networks, will be examined separately.
Since the feature will be introduced through telecom operators, users will not need to install a separate application or submit an individual request to activate it.
What about privacy and business calls?
The DoT has prescribed safeguards for the implementation of CNAP. Telecom operators must ensure that the system does not retain the caller’s name identity after the incoming call is completed, as part of the prescribed query-response mechanism.
Businesses and users with bulk connections may also be allowed to display a verified preferred name instead of the name recorded in their subscriber details. Such names must meet the government’s verification requirements, including registration as a trademark or trade name.
The directive also provides an exception for subscribers who have validly opted for Calling Line Identification Restriction (CLIR), under which their calling name identity will not be displayed.
Will it stop scam calls?
It may help, but the name on screen is only as reliable as the operator’s records. It is the name on the connection’s paperwork, which isn’t necessarily the person calling. A SIM registered to a relative, a company or a fake ID would display that name. Operators have been told to keep their databases accurate, and how well they do will decide whether the service reduces fraud or just adds a name to the same problem.
What should mobile users expect from November 1?
With the new system, users will be able to identify many previously unfamiliar numbers directly from their incoming-call screens. The change is expected to provide an additional layer of transparency in phone communications and make it easier to distinguish recognised callers from unfamiliar ones.
However, CNAP is primarily a caller identification facility, not a complete solution to spam calls or online fraud. Users should still verify suspicious requests independently and avoid sharing confidential information over the phone.
The mandatory rollout is scheduled to begin on November 1, 2026, with initial implementation on 4G and newer-generation wireless networks.
