Bharat Sanchar Nigam Limited (BSNL) is reportedly preparing to introduce Caller Name Presentation (CNAP) across India, marking a major step forward in enhancing user safety and transparency in telecom services.

The upcoming feature will allow users to see the name of incoming callers directly on their phone screens, eliminating the need for third-party apps like Truecaller or paid subscriptions. With spam calls becoming a growing concern, this move is expected to significantly improve how users manage unknown calls.

What is CNAP and Why It Matters

Understanding Caller Name Presentation (CNAP)

CNAP, short for Caller Name Presentation, is a telecom feature that displays the registered name of the caller when a call is received. Unlike traditional caller ID systems, CNAP uses official KYC records maintained by telecom operators to provide accurate identity information.

Why CNAP is Important

Helps users identify unknown callers instantly

Reduces reliance on third-party apps

Enhances privacy and security

Assists in avoiding spam and fraudulent calls

This feature is particularly useful in a time when spam calls and scams are on the rise across India.

BSNL’s CNAP Rollout Plan

Zone-Wise Integration Underway

BSNL has reportedly already deployed the CNAP solution and is currently integrating it across networks in a zone-wise manner. This phased rollout ensures smoother implementation and compatibility with other telecom operators.

Nationwide Launch Timeline

According to industry reports, BSNL is expected to roll out CNAP nationwide within the next 3 to 4 months, once integration with private networks is complete.

Collaboration with Telecom Ecosystem

TRAI and DoT Initiative

The CNAP system is part of a broader initiative led by the Telecom Regulatory Authority of India and supported by the Department of Telecommunications (DoT). The feature was introduced in phases starting in the second half of 2025.

Technology Development by C-DoT

The solution for BSNL has been developed and implemented by the Centre for Development of Telematics, a government-owned telecom R&D center known for building indigenous telecom technologies.

How CNAP Works

KYC-Based Caller Identification

The CNAP system uses KYC (Know Your Customer) data submitted by users during SIM registration. This ensures that:

Caller names are verified and authentic

No additional app or internet connection is required

No Subscription Required

Unlike apps such as Truecaller, CNAP:

Is completely free

Works directly through the telecom network

Does not require user sign-up or permissions

Compatibility and Current Limitations

Cross-Network Challenges

Currently, CNAP works most effectively when both the caller and receiver are on the same telecom network. However, telecom operators are actively working to improve cross-network compatibility.

Device Support

Available on smartphones

Not supported on basic feature phones

How BSNL Compares with Private Telecom Operators

Private telecom players like:

Reliance Jio

Bharti Airtel

Vodafone Idea

have already begun implementing CNAP for their users. With BSNL joining the initiative, the feature is expected to reach a much wider audience, especially in rural and semi-urban areas.

Benefits of CNAP for Users

Enhanced Call Transparency

Users can instantly identify who is calling, even if the number is not saved.

Reduced Spam & Fraud

Helps in avoiding unwanted calls and potential scams.

No Third-Party Dependency

Eliminates the need for external apps and subscriptions.

Improved User Experience

Seamless integration within the telecom network ensures ease of use.

Availability

The CNAP feature is expected to roll out for BSNL users across India in the coming months. Once fully implemented, it will be available automatically on supported devices without requiring any manual setup.

Conclusion

BSNL’s upcoming rollout of CNAP represents a major upgrade in telecom user experience, bringing built-in caller identification directly to users without relying on external apps.

As India continues to tackle spam calls and digital fraud, this initiative could play a crucial role in improving trust and transparency in communication. With nationwide availability expected soon, BSNL users can look forward to a safer and smarter calling experience in the near future.
