BSNL to Roll Out Caller Name Service Nationwide by End of March 2026

Representational

BSNL is preparing to commercially launch its Caller Name Presentation (CNAP) service across India by March 31, 2026, with zone-wise testing underway and interoperability trials being conducted with Jio, Airtel, and Vodafone Idea. The service will display verified caller names directly on users’ screens, reducing reliance on third-party apps like Truecaller.

Key Highlights of BSNL’s CNAP Rollout

• Launch timeline: Expected pan-India availability by March 31, 2026.
• Technology partner: CNAP platform developed by C-DoT.
• Testing: Ongoing zone-wise integration and interoperability trials with private telcos (Jio, Airtel, e Idea).
• Data source: Caller names displayed using KYC-verified subscriber records.
• User control: CNAP will be enabled by default, with opt-out options available.

Why CNAP Matters

• Consumer protection: Helps combat spam, fraud, and phishing calls.
• Alternative to apps: Reduces dependence on third-party caller ID apps like Truecaller.
• Regulatory push: Supported by TRAI to improve transparency in mobile communication.
• Market impact: BSNL’s rollout could pressure private operators to accelerate adoption.

Comparison: CNAP vs. Truecaller

Feature	CNAP (BSNL)	Truecaller
Data source	Verified KYC records	Crowdsourced user data
Accuracy	High (official subscriber info)	Variable, sometimes inaccurate
Integration	Native, network-level	App-based, requires installation
Privacy	Controlled by telecom operators	Dependent on app permissions

Challenges Ahead

Editorial Take

BSNL’s CNAP launch represents a strategic opportunity for the state-owned operator to regain relevance in India’s telecom market. By offering a trustworthy, network-level caller ID solution, BSNL could position itself as a leader in consumer protection and digital trust. If private telcos follow suit, CNAP may become a standard feature across Indian mobile networks, reshaping how users interact with unknown calls.
