India’s mobile users are expected to start seeing the names of callers alongside their phone numbers from 1 November 2026, as telecom operators prepare to roll out Calling Name Presentation (CNAP) under a Department of Telecommunications (DoT) directive.
The system is designed to help people identify unknown callers without depending entirely on third-party caller-ID apps. For domestic calls from numbers that are not saved in a user’s contacts, the name recorded in the caller’s telecom subscriber database is expected to appear on the incoming-call screen.
The rollout will initially cover 4G and newer mobile networks. The DoT has said that implementation on 2G and 3G networks, as well as landline connections, will be considered separately.
What is CNAP and when will it start?
Calling Name Presentation is a telecom-network feature that displays the caller’s registered name alongside the phone number when a call arrives. The DoT’s directive instructs telecom operators to introduce the service across their service areas from 1 November 2026.
The feature is intended to work by default, without requiring mobile users to download an app or submit a separate request. Operators have already conducted trials on 4G and newer wireless networks.
However, the practical experience may depend on network and device compatibility as the rollout begins. The directive does not mean every incoming call will necessarily show an identifiable individual or business name.
What name will appear on your phone?
The name displayed will depend on whether the number is saved in your contacts and where the call originates.
| Incoming call | What users can expect |
|---|---|
| Number saved in contacts | The name saved in your phone will take priority. |
| Unsaved domestic number | The caller’s name recorded in the originating telecom operator’s subscriber database should appear with the number. |
| Unsaved international number | The display is expected to show “International Call” rather than the caller’s registered name. |
| Caller using Calling Line Identification Restriction (CLIR) | The caller’s name will not be displayed under the stated rules. |
| Eligible business or bulk connection | A verified preferred business name may be displayed instead of the subscriber-record name. |
For example, if an unknown domestic number calls you, the incoming-call screen may show the subscriber name associated with that number instead of only displaying the digits. If you have already saved the number, your own contact label will continue to take precedence.
How will CNAP determine the caller’s name?
CNAP will rely on subscriber information maintained by telecom operators rather than a crowdsourced database of names and numbers.
When a call arrives, the receiving operator will obtain the relevant name information from the operator whose network the call originates on. The name will then be presented alongside the calling number.
This makes the system different from a contact-sharing service. It is based on telecom subscriber records associated with the connection, rather than on how other users have saved or labelled a number.
That distinction also creates a limitation: the displayed name may not always be the name by which a person is commonly known. If subscriber records are outdated, incorrect or do not reflect a caller’s current identity, the displayed information may not be immediately recognisable.
What happens to international calls?
For an unsaved number originating outside India, the prescribed display is “International Call” rather than a name retrieved through the domestic CNAP process.
This means users should not assume that every overseas caller will be identified by an individual or company name. The international-call label can provide a useful indication of the call’s origin, but it does not establish whether the call is legitimate.
Users should remain cautious if an international caller unexpectedly asks for money, banking information, passwords or one-time passwords (OTPs).
CNAP vs Truecaller and other caller-ID apps
CNAP and third-party caller-identification apps both aim to help users understand who is calling, but they use different sources of information.
| Feature | CNAP | Third-party caller-ID apps |
|---|---|---|
| Main information source | Telecom subscriber records | App-specific databases and other available data sources |
| Installation | No separate caller-ID app required | Usually requires an app |
| Unsaved domestic calls | Displays the name recorded by the originating operator | May show a name or label available in the app’s database |
| Spam labels and community reports | Caller-name presentation is the primary function | Some apps offer spam warnings, user reports and additional features |
| Accuracy | Depends partly on the correctness of subscriber records | Depends on the app’s data, reporting and identification methods |
CNAP could reduce the need to rely on an app just to see a registered name for an unknown domestic caller. However, it should not be treated as a complete replacement for every caller-ID feature.
An operator-recorded name is also not the same as a security verification. Seeing a familiar name does not prove that the call is safe, and a name alone cannot rule out fraud or impersonation.
Can businesses display their brand names?
The DoT’s instructions allow eligible business and bulk-connection subscribers to use a preferred name in place of the name held in their subscriber records, subject to verification by the telecom operator.
The preferred name must be a trademark registered with the relevant Trade Marks Registry or a trade name registered on the GST portal. Operators are required to verify the supporting documents before allowing the name to be displayed.
This could help users recognise legitimate business calls from eligible connections. It does not mean every company will automatically appear under its familiar brand name from the first day of rollout.
What about privacy and incorrect names?
The DoT has instructed operators to follow a security-by-design approach. The name lookup process is intended to avoid retaining the queried calling-name information after the call ends.
Operators must also establish a time-bound grievance-redressal mechanism for CNAP-related complaints. Users who see an incorrect or confusing name should contact their telecom operator through its official customer-care or complaint channels to seek clarification or correction.
The stated rules also exclude the names of callers who have opted for Calling Line Identification Restriction (CLIR). The directive does not mean that a caller’s name will be displayed in every circumstance.
Will CNAP stop spam and fraud calls?
CNAP may help users make a more informed decision before answering an unfamiliar number. It can provide an additional clue about who is calling, particularly when a domestic number is not saved in the recipient’s contacts.
But it is not a guarantee against scams. A displayed name does not independently authenticate the caller, verify the purpose of the call or establish that a request for payment is genuine. Users should never share an OTP, UPI PIN, banking password or other sensitive information merely because an incoming call displays a recognisable name.
The effectiveness of CNAP will also depend on the accuracy of telecom records, network implementation and how quickly operators resolve incorrect-name complaints.
What mobile users need to do before 1 November
For most users, no separate registration or app installation should be necessary. CNAP is intended to be provided by telecom operators by default on supported networks.
After the rollout begins, users can check how incoming calls appear on their phones. If an unsaved domestic number continues to show only its number, the feature’s availability on the user’s network and device may need to be confirmed with the operator.
The 1 November deadline marks the planned start of the service on 4G and newer networks, not a guarantee that every caller will be identified by name. CNAP adds a network-based layer of caller information, but users will still need to exercise caution when dealing with unfamiliar calls.
