India to Display Caller Names on Unknown Numbers from November 1

The Department of Telecommunications (DoT) has issued a directive requiring all telecom operators to activate Caller Name Presentation (CNAP) technology across their networks by November 1. The measure is designed to enhance security and transparency for India's millions of mobile phone users.

Under the new protocol, when users receive an incoming call from an unknown number, their devices will display the caller's name alongside the phone number, provided the information is available in telecom databases or linked identification systems. The initiative aims to reduce confusion caused by unidentified calls and help users make informed decisions about whether to answer.

The CNAP implementation represents a significant shift in India's telecommunications landscape, addressing longstanding user concerns about unsolicited or potentially fraudulent calls. Telecom operators have been given adequate notice to integrate the necessary infrastructure and backend systems required to support the functionality across all network technologies, including 2G, 3G, 4G, and 5G services.

Industry analysts expect the rollout to proceed smoothly given the standardized nature of CNAP technology and the extended implementation timeline provided to service providers. The system is expected to cover both landline and mobile networks, creating a comprehensive caller identification network across the country's telecommunications infrastructure.
