Vodafone‑Idea rolls out CNAP service nationwide in India

Vodafone‑Idea (VI) has activated its Calling Name Presentation (CNAP) service across India, the operator confirmed on 30 December 2025. The move means subscribers on the VI network will now see a caller’s name, not just the phone number, when they receive an incoming call.

Vodafone‑Idea CNAP service shows caller name from KYC

CNAP delivers the caller name held by the telecom operator at the network level. In VI’s implementation, the name that appears on a recipient’s handset is taken from the KYC details provided by the calling subscriber. That means even if the caller’s number is not saved in the recipient’s address book, the registered name can still appear on the incoming call screen.

The functionality is currently available for on‑net calls, so both parties must be on the VI network for the name to be presented. VI has indicated plans to extend the service to cross‑network calls in future, which would allow CNAP to work when callers and recipients are on different operators’ networks.

How CNAP differs from third‑party ID apps

Services such as Truecaller identify callers using crowd‑sourced or user‑submitted databases. By contrast, CNAP operates at the carrier level and uses verified subscriber information. That difference can make CNAP more reliable for showing the name an operator has on record, while third‑party apps may show alternate or unverified labels based on public contributions.

Consumer benefits and fraud prevention

Telecoms industry observers say CNAP can strengthen consumer protections by giving recipients immediate context about incoming calls, which may reduce the success of impersonation or phishing attempts that rely on hidden or spoofed numbers. As fraud cases have risen, the ability to display a verified name could help users make faster decisions about whether to answer a call.

However, the service is not a complete defence against number‑spoofing techniques. Its effectiveness will depend on broader adoption across operators and on measures taken by regulators and carriers to verify and secure subscriber records.

Privacy and operational considerations

Because CNAP displays the name linked to a subscriber’s KYC, the rollout raises practical questions about privacy and data accuracy. Users who prefer not to show their registered name when calling may want to review their account settings or contact their operator. Regulators and operators typically balance identification features with privacy safeguards and may issue guidance on permitted uses.

VI’s nationwide activation marks a notable step for telecom services in India, signalling an industry shift towards network‑level caller identification. Wider adoption, cross‑network interoperability and clear privacy practices will determine how quickly CNAP becomes a standard tool in reducing telecom fraud and improving the calling experience.
