The Indian government has announced a new regulation for telecom service providers (TSPs) that mandates the display of callers’ registered names alongside their phone numbers for all incoming calls. This initiative, effective from November 1, 2026, aims to help users identify unknown callers and reduce spam and fraudulent activities.
Implementation of CNAP Service
To enforce this regulation, the Department of Telecommunications has circulated a directive encouraging TSPs to implement the Calling Name Presentation (CNAP) service. According to a circular dated October 13, 2026, issued by the Ministry of Communications, the CNAP service will display the calling user’s name on the recipient’s device when a call is received.
The calling name identity is derived from subscriber data records maintained by the originating TSP, ensuring that this information is included in the caller’s line identification. Currently, the focus is on applying this system to wireless terrestrial networks utilizing 4G and later technologies, with potential future rollouts for 2G, 3G, and public switched telephone networks (PSTNs).
User Call Identification Process
Under the new guidelines, the caller’s number will appear first, followed by their name, if saved in the recipient’s contacts. For numbers not stored in contacts, the telecom operator’s database will provide the name for domestic calls, while calls from overseas will display “International Call.” Originating TSPs must maintain databases that map subscriber names to numbers, enabling receiving operators to query and display this information accurately.
Additionally, telecom operators must offer a Calling Line Identification Restriction (CLIR) feature, allowing users to hide their caller information if desired. The Ministry of Communications emphasizes a secure-by-design approach to protect communication security, ensuring no retention of caller identities once calls conclude.
Business and Bulk Connection Considerations
For users with business or bulk connections, the regulation offers the option to use a “preferred name” instead of the standard calling name identity. This preferred name must be a registered trademark or trade name, as recorded with the Trade Marks Registry or on the Goods and Services Tax portal.
For new connections, the preferred name must be documented in the customer application form and subscriber data record, with original proof of registration presented to the originating TSP. This ensures that businesses can maintain their brand identity during communications while complying with the new regulations.
As India advances these telecom regulations, the focus remains on enhancing call transparency and reducing unsolicited communication, fostering a more secure and user-friendly telecommunication environment.
