India Mandates Registered Caller Name Display on 4G and Newer Networks From November 1

Summary: India's Department of Telecommunications issued a circular dated October 13, 2026 directing telecom service providers to display callers' registered names alongside their numbers for incoming calls starting November 1, 2026, through a Calling Name Presentation (CNAP) service. The system targets 4G and higher wireless networks, requires each originating operator to maintain a database mapping subscriber names to numbers that the receiving operator queries, and includes a Calling Line Identification Restriction facility for users who want to hide their identity.
Why it matters: Every originating carrier now has to build and secure a name-to-number database that other operators query on each call, and the Ministry is explicitly asking for a secure-by-design rollout - a subscriber identity store tied directly into live call routing is a new target for anyone who wants to spoof or harvest identities at national scale.
