DoT mandates caller name display on 4G, 5G networks from Nov 1, offers no opt-out

The Department of Telecommunications (DoT) has ordered telecom operators to display callers’ registered names by default on 4G and 5G networks across India from November 1, 2026. The caller name display order gives most users no way to opt out. Under the Calling Name Presentation (CNAP) service, a caller’s name from their operator’s subscriber records will appear whenever the person they call hasn’t saved their number, according to the DoT circular dated October 13.
