Centre Directs Telcos To Display Caller Names From November 1

CNAP, or calling name presentation, displays a caller’s name alongside the telephone number. From November 1, 2026, it will be enabled by default on 4G and newer wireless networks. Users will not need to opt in. This matters because recipients can identify callers without first saving their numbers.

For example, an incoming call can show the caller’s subscriber-record name beside the number. The originating telecom service provider maintains a database connecting subscriber names with telephone identifiers. The recipient’s operator queries that information and displays the name, but must not retain it after the call ends. Existing saved contacts remain unchanged.

The rollout follows trials on 4G and newer networks and TRAI recommendations issued in February 2024. Businesses and bulk-connection users may display verified trademarked or GST-registered trade names. Service on 2G, 3G, and landlines will be examined separately.

The initial rollout is broad but not universal across every connection type. Telecom operators must enable CNAP by default throughout their service areas on 4G and higher-generation wireless networks from November 1, 2026. This covers the newer mobile networks used by many subscribers and requires no separate user opt-in.

For instance, a call made over a 4G network can trigger a name request when it reaches the recipient. The recipient’s operator can then show the caller’s name beside the number. The article does not say that CNAP will immediately cover older mobile networks or fixed-line services. Instead, those categories have a separate review.

Rollout on 2G and 3G networks, along with landline connections, will be examined separately. Operators have already conducted trials on 4G and newer networks. They must also ensure identification requests do not reduce service quality, while creating complaint-handling systems.

CNAP works through cooperation between the two telecom operators handling a call. The originating telecom service provider must maintain a database linking each subscriber’s name to a telephone identifier. This gives the network a source for the caller’s name when another subscriber receives the call.

For example, when a caller places a call, the recipient’s operator sends a request to the originating operator’s database. It retrieves the name recorded there and displays it with the caller’s number. The recipient’s operator does not keep that name after the call ends. The mechanism therefore supports identification while requiring limited handling of the information.

The guidelines make privacy a specific responsibility for telecom operators. They must prevent caller names from being stored after calls, keep identification requests from affecting service quality, and create systems for resolving complaints. The article does not describe the technical signalling used for the query.

Users on 4G and newer wireless networks will encounter CNAP automatically because the service will be enabled by default. They will not need to activate it or request access. During an incoming call, the screen can show the caller’s name alongside the number, even if that number is not saved in the recipient’s contacts.

Saved contacts are not replaced by CNAP. If a recipient already has a number stored, that saved contact information will continue to remain unchanged. For other callers, the displayed name comes from the originating operator’s subscriber database. The recipient’s operator queries that database but must discard the caller name after the call ends.

There is an important exception. Callers who have activated calling line identification restriction, or CLIR, to hide their identity are exempt from CNAP. The article does not say that users can otherwise opt out of default CNAP on covered networks.

For ordinary subscribers, the displayed name is the name recorded in the telecom operator’s subscriber database. The originating operator supplies that name through the CNAP process. The recipient’s operator displays it beside the telephone number, so the visible result depends on verified operator records rather than the recipient’s saved contacts.

Businesses and bulk-connection users have another option. They may request a preferred name instead of the name in their subscriber records. The alternative must be supported by a trademark registered with the Trade marks registry or a trade name registered on the GST portal. Operators must verify the documents before approving the change.

Eligible users can also request changes later, subject to verification. Telecom operators, including Jio, Airtel, and Vodafone, are responsible for checking the supporting material. The article does not state that individual subscribers may freely choose any displayed name. The operator database remains the controlling source.

TRAI’s position changed over time. Earlier, it had proposed activating CNAP only when a user requested the service. In October last year, however, TRAI supported making CNAP available by default. That marked a move away from an opt-in model toward automatic availability on covered networks.

The article links the rollout to trials conducted by telecom operators on 4G and higher-generation networks. It also identifies TRAI’s recommendations issued in February 2024 as part of the background. These developments preceded the Department of Telecommunications’ direction for operators to roll out CNAP across their service areas from November 1, 2026.

The article does not give a specific reason for TRAI’s change beyond this policy and trial history. It does establish the practical result: users on 4G and newer wireless networks will receive CNAP by default without opting in. Older networks and landlines remain subject to separate examination.

Calling-line identification, or CLI, is the information associated with an incoming call that identifies its origin. Under the amended unified licence definition, CLI includes the caller’s name as recorded in the telecom operator’s subscriber database, alongside the caller’s telephone identifier. CNAP is the service that presents this information to the recipient.

The originating telecom service provider maintains the link between a subscriber’s name and telephone identifier. When a call arrives, the recipient’s operator queries that source and displays the caller’s name. It does not retain the name after the call ends. This lets the network reveal identity information without keeping it in the recipient’s operator system.

Calling-line identification restriction, or CLIR, works in the opposite direction. It is a facility callers can activate to hide their identity. Callers using CLIR are exempt from CNAP. The article does not describe the underlying network signalling for either CLI or CLIR.
