The Department of Telecommunications (DoT) has issued a binding directive requiring all licensed telecom service providers to launch Calling Name Presentation (CNAP) across India on November 1, 2026. This mandate ends the era of 'Unknown' domestic callers. From that date, every incoming call on 4G and higher networks will display the caller’s registered name alongside their phone number, with no separate user opt-in required.
The mechanism is straightforward but relies entirely on operator databases. When a call lands, the receiving network queries the originating operator’s subscriber records to fetch the name. If the number is in your contacts, your saved label appears. If it’s an unsaved domestic number, the name registered with the original operator pops up. For international calls, the screen will simply read 'International Call' to prevent cross-border data complexities and privacy breaches.
Businesses face stricter rules. They can’t just pick a nickname. To display a preferred name, companies must prove it is a registered trademark with the Controller General of Patents, Designs and Trade Marks or a registered trade name on the GST portal. Telecom operators must verify these documents against originals and retain true copies. New connections must have this preference recorded in the customer application form; existing users must apply through a specific verification mechanism.
Privacy and security are baked into the design. The DoT mandates a 'security-by-design' approach where calling name data is not retained after the call ends. Operators must ensure their infrastructure handles these queries without slowing down network speed. Users who have already enabled Calling Line Identification Restriction (CLIR) remain exempt, and their names will not appear on others’ screens.
The central government expects this to curb spam and fraudulent calls significantly. Telecom providers must set up grievance redressal mechanisms to handle complaints about incorrect names or service disruptions within specified timeframes. The next step? Operators have a tight deadline to update their core network infrastructure and databases to comply with the DoT’s technical specifications before the November 1, 2026, launch date.
