Mobile users across India are set to get a new feature that will make identifying unknown callers easier. From November 1, 2026, telecom operators are expected to roll out the Calling Name Presentation (CNAP) service, which will display the caller’s name along with their mobile number when someone makes a call.
The government has directed telecom companies to introduce this facility to help users identify incoming calls and reduce the risks associated with spam and fraudulent phone calls.
The service is expected to be activated automatically on 4G and 5G networks, meaning users will not need to install an additional application or change their phone settings. However, support for older 2G and 3G networks has not yet been finalised.
CNAP is also expected to provide a telecom-based alternative to third-party caller identification applications such as Truecaller.
How Will the CNAP Caller Name Service Work?
Under the CNAP system, an incoming call will display both the caller’s mobile number and registered name on the recipient’s phone screen.
If the caller’s number is already saved in the recipient’s contact list, the saved contact name will appear. For numbers that are not stored, the name will be retrieved from the relevant telecom operator’s customer database.
Calls coming from outside India will be identified with an ‘International Call’ label.
To make this system work, telecom operators will maintain secure databases containing customers’ registered names and mobile numbers. When a call is placed, the network will use the available information to identify the caller and transmit the name to the receiving phone.
CNAP Service: Privacy Rules and CLIR Facility
Privacy protection is an important part of the proposed caller identification system. According to the information provided, the caller’s name will be displayed during the call but will not be retained after the call ends.
Users who have activated Calling Line Identification Restriction (CLIR) to keep their identity private will also have their names protected from being displayed through the service.
The system will rely on telecom operators’ registered customer information rather than requiring users to depend entirely on external caller identification applications.
How Will CNAP Benefit Mobile Users?
The introduction of CNAP could make it easier for people to decide whether to answer calls from unfamiliar numbers.
Displaying the caller’s registered name alongside the number may help users identify unknown callers and avoid some unwanted or suspicious calls. It could also reduce dependence on third-party applications for basic caller identification.
However, users may experience some technical issues during the initial rollout. The system is expected to improve as telecom operators implement and refine the service.
Overall, CNAP is intended to make incoming calls more transparent by providing users with additional information about who is calling.
