Tech: Now you'll know who's calling without Truecaller—BSNL is introducing a fantastic new feature..
Bharat Sanchar Nigam Limited (BSNL) is reportedly working on adding the CNAP (Caller Name Presentation) feature for its users. Private telecom companies in India have already implemented this for their customers, and the state-run telecom operator is expected to launch it nationwide soon. It is reported that BSNL has already deployed this solution. CNAP is an initiative by the Telecom Regulatory Authority of India (TRAI) that allows users to view the caller's name when receiving an incoming call. This feature is expected to help users make informed decisions before answering a call.
**BSNL to Integrate CNAP in a Zone-wise Manner**
According to a report by ETTelecom, BSNL is currently testing the integration of its CNAP service with private telecom operators. An industry executive familiar with the matter told the publication, "Reliance Jio, Bharti Airtel, and Vodafone Idea (Vi) were the first to implement this. For BSNL, the solution has already been deployed, and its integration is now proceeding in a zone-wise manner."
The executive reportedly stated that following the integration, BSNL would roll out CNAP across the entire country within three to four months. The executive also reportedly mentioned that the Centre for Development of Telematics (C-DoT) developed and implemented this solution for the state-run telecom operator.
Introduced by TRAI, CNAP was launched in a phased manner during the second half of 2025. The Department of Telecommunications (DoT) conducted trial runs of this feature on both 4G and 5G networks. Designed to curb spam calls, this feature is not available on feature phones.
The CNAP service displays the names of unknown callers on the phone without requiring any additional subscription fees. This service does not require internet access or the use of third-party applications such as Truecaller. This feature utilizes KYC-verified subscriber details to display the caller's name.
Currently, the CNAP service functions correctly only when both the caller and the receiver are on the same network. However, it is reported that operators are still working on resolving issues related to the cross-network compatibility of this feature.
