Jio, Airtel And Vi Launch CNAP: Seeing names on calls from unsaved numbers is now part of a wider telecom security push. CNAP shows verified SIM owner names using operator databases, not user tags. With scam calls rising and BSNL next in line, is this the biggest change to calling yet?

Why Unknown Calls Are Now Showing Names On Your Phone

If calls from unsaved numbers are suddenly displaying names on your phone, there is no cause for concern. Telecom operators in India have started rolling out a new feature called Calling Name Presentation, or CNAP.

This service shows the verified name of the caller even when the number is not saved in your phone or SIM card. The name displayed is the same one registered during SIM issuance using Aadhaar or other approved KYC documents.

How CNAP Is Different From Truecaller

CNAP is fundamentally different from apps like Truecaller. Third party caller ID apps rely heavily on user generated data, which often leads to incorrect names, spam tags, or misleading identities.

CNAP, on the other hand, is based entirely on the official and verified subscriber database maintained by telecom operators. This eliminates fake names and reduces the risk of misidentification, making caller information more reliable.

Telecom Operators Offering CNAP

Currently, Reliance Jio, Bharti Airtel, and Vodafone Idea have started offering CNAP to their customers on a trial or pilot basis. The rollout is being done in phases across different telecom circles.

Bharat Sanchar Nigam Limited customers will have to wait for now. However, BSNL has confirmed that it will introduce the Caller ID feature soon as part of the nationwide rollout.

States Where CNAP Has Been Rolled Out

According to reports, Jio has already launched CNAP in several states, including Bihar, UP East, West Bengal, Rajasthan, Punjab, Kerala, Assam, Jharkhand, and Odisha.

Other operators are also implementing the feature gradually, in line with directives issued by the Telecom Regulatory Authority of India.

TRAI Directive Behind CNAP Rollout

TRAI has instructed all telecom companies to introduce a caller identification system to protect users from cyber crime, fraud, and spam calls. Under CNAP, verified caller names are displayed even for unsaved numbers.

The move is part of a broader effort to make telecom communication safer and more transparent for mobile users.

Silent Calls And Government Warning

Alongside CNAP, the Department of Telecommunications has issued a warning about silent calls. These are calls where no voice is heard after answering and are often used by scammers to check whether a number is active.

Users are advised to block such numbers immediately. Suspicious numbers can also be reported through the Sanchar Saathi portal.

Network Support And User Control Options

CNAP is enabled by default on all 4G and above networks. However, users retain control and can disable the service if they choose.

Subscribers who have activated the Calling Line Identification Restriction service will be exempt, meaning their names will not be displayed when they make calls.

BSNL Confirms CNAP Is Coming

Gyanendra Kumar Dwivedi, General Manager of BSNL’s Ayodhya Circle, has confirmed that TRAI has issued the directive and BSNL customers will soon receive the Caller ID feature.

Why CNAP Matters

Experts believe CNAP can significantly reduce fear around unknown calls. By displaying verified names instead of random tags, it makes calling safer, more reliable, and less prone to misuse.

As the feature expands nationwide, CNAP could redefine how mobile users in India respond to unfamiliar numbers.
