India Mandates Registered Caller Name Display on 4G and Newer Networks From November 1

India is requiring telecom service providers to display two pieces of information for incoming calls from covered networks: the caller’s number and the caller’s registered name. The Department of Telecommunications has directed operators to implement Calling Name Presentation, or CNAP, starting November 1, 2026. The goal is to help people recognize unknown callers and address spam or fraudulent calls.

The number will remain the first field, as it is today. The second field will show a name. If the recipient has saved the number, the phone will display the contact name. If not, the receiving operator will retrieve the caller’s name from the originating operator’s subscriber database. Calls from outside India will be labeled “International Call.”

The first rollout mainly targets wireless terrestrial networks using 4G and newer technologies. CNAP for 2G, 3G, and public switched telephone networks will be considered separately. Operators must also support privacy, security, and reliable name queries.

Calling Name Presentation, or CNAP, is a service that presents the calling user’s name on the recipient’s phone when an incoming call arrives. It is designed to add identity information, making an unfamiliar number easier to understand. The name is the calling user’s identity recorded in the originating telecom operator’s subscriber data.

Ordinary caller ID already displays the incoming number. Under CNAP, the number remains the first field, while the name appears in a second field. If the recipient has saved that number, the corresponding contact name is shown. If the number is unsaved, the receiving operator queries the originating operator’s database for the registered calling name. An overseas caller is shown as “International Call.”

Thus, CNAP does not replace the number. It supplements it with a name drawn from operator records. The first phase focuses on 4G and newer wireless terrestrial networks. Other networks will be addressed separately after examination.

The initial CNAP rollout is aimed mainly at wireless terrestrial networks built with 4G and higher-generation technologies. These networks are the first target for mandatory display of a caller’s name with the incoming number. The requirement concerns incoming calls handled through the covered telecom services.

For example, when a person receives a call over a covered 4G network, the number appears first and a name can appear second. A saved number uses the recipient’s contact name. An unsaved domestic number uses the calling name stored by the originating operator. A call originating outside India is labeled “International Call,” rather than receiving a domestic subscriber name.

The circular does not bring every network into the first phase. CNAP for 2G and 3G networks, along with public switched telephone networks, will be taken up separately after examination. The article gives no separate later date for those networks, so their future rollout remains unspecified.

The display follows a stated order of preference. First, the receiving phone checks whether the number is already saved in the recipient’s contacts. If it is, the corresponding contact name is shown. This lets a personally saved name take priority over the operator’s subscriber record.

If the number is not saved, the receiving telecom operator queries the originating operator’s subscriber database. That database maps subscriber names to numbers and supplies the calling name identity for domestic calls. For calls originating outside India, the display uses the label “International Call.” The receiving operator presents the result to the caller’s recipient.

Business or bulk-connection users can choose a preferred name instead. It must be either a trademark registered in the user’s name or a trade name registered on the Goods and Services Tax portal. For new connections, proof must be presented and the preferred name recorded in the application and subscriber data record.

Displaying a registered name gives recipients more than an unfamiliar number when a call arrives. That extra identity clue could help people decide whether a call appears expected, recognizable, or suspicious. The government is introducing CNAP specifically to help identify unknown callers and tackle spam or fraudulent calls.

For example, an unsaved domestic number would show the name held in the originating operator’s subscriber database. A person could compare that displayed identity with the call’s context before deciding how to respond. A business account could show an approved trademark or GST-registered trade name. Calls from outside India would be marked “International Call,” offering a clear origin category.

CNAP is an identification aid, not a guarantee that a call is genuine. The article does not state that displaying a registered name will eliminate scams or prevent every fraudulent call. Operators must securely manage the system, avoid retaining the calling name after the call ends, and maintain required service quality.

The guidelines include a privacy choice called Calling Line Identification Restriction, or CLIR. Telecom operators are expected to provide it so users can choose to hide their caller identity when making calls. This gives callers a way to limit the name information presented to the recipient.

There is also a business exception to the ordinary registered-name display. Users with business or bulk connections can select a preferred name. That name must be a trademark registered in the user’s name or a trade name registered on the Goods and Services Tax portal. For a new connection, the preferred name must be recorded in both the customer application form and subscriber data record.

The operator must receive original proof and attach true copies to the application. The circular also requires a secure-by-design approach. Calling name identity must not be retained after the incoming call ends. Operators must provide the infrastructure needed for efficient queries and maintain lawful service quality.

The network’s basic identification chain begins with the originating telecom service provider. Every originating provider must establish and maintain subscriber data that maps names to numbers. The calling name identity is the caller’s name recorded in that provider’s subscriber data record and included in the caller’s calling-line information.

When the call reaches another network, the operator serving the recipient queries the originating operator’s database. It retrieves the calling name identity and presents it on the recipient’s phone. The number remains the first displayed field, while the name appears second. A saved contact name takes priority on the recipient’s device; an overseas call receives the “International Call” label.

The circular requires databases, network capacity, and connectivity to support these queries efficiently. Operators must also secure the system, avoid retaining the calling name after the incoming call finishes, and maintain applicable quality-of-service standards. The article does not describe the phone’s internal display technology.
