India’s telecom operators, Vodafone Idea, Bharti Airtel, and Reliance Jio, are set to introduce Calling Name Presentation (CNAP) in collaboration with global technology giants like HP, Dell, Ericsson, and Nokia. This move is expected to enhance caller identification and reduce spam calls.

What is CNAP?

Calling Name Presentation (CNAP) is a technology that enables mobile users to see an incoming caller’s name, similar to Truecaller. The system retrieves the caller’s name from a telecom operator’s database and displays it on the recipient’s phone. Unlike third-party apps, CNAP will rely on the official Customer Application Form (CAF) details provided during SIM registration.

Regulatory Push for CNAP Implementation

In February 2024, the Telecom Regulatory Authority of India (Trai) recommended the adoption of CNAP for all smartphones, urging telecom operators to introduce the feature. In January 2025, the Department of Telecommunications (DoT) directed telecom companies to implement the service as soon as possible. The goal is to protect users from fraudulent, spam, and scam calls by ensuring better caller transparency.

How Will CNAP Work?

Each telecom provider will maintain a database of subscriber names linked to mobile numbers. When a call is made, the system will fetch the caller’s registered name and display it on the recipient’s screen. 

Initially, CNAP will work only within the same network, meaning an Airtel-to-Airtel call will display the caller’s name, but cross-operator name display, such as Jio-to-Vodafone, will require regulatory approval for data sharing between telecom providers.

Challenges in Implementation

Despite its potential benefits, CNAP faces several challenges. The service will not be available for feature phones and 2G users due to technical limitations. Privacy concerns also arise, as some users may be reluctant to have their names displayed automatically. Additionally, interoperability issues between telecom operators could delay full-scale adoption, as cross-network caller name display requires regulatory approval and data-sharing mechanisms.

Conclusion

The introduction of CNAP marks a major step in combating spam and fraudulent calls. While the service will initially have limitations, it has the potential to transform caller identification in India. Users can expect a more secure and transparent communication experience as telecom operators work towards full-scale implementation.
