India’s Department of Telecommunications (DoT) orders telecom service providers to roll out Calling Name Presentation (CNAP), which shows the caller’s registered name alongside their phone number on the recipient’s device, starting November 1. Multiple outlets report that the change targets spam and fraud by reducing the “unknown number” problem.
According to coverage, the rollout begins on 4G and newer-generation networks, with implementation instructed across service areas from the same date. Some reports specify that 5G will be included under the broader “4G and newer” instruction, while calling name display for older technologies such as 2G/3G and landlines will be considered separately. DoT also requires that CNAP be protected from tampering, and that new authorised telecom operators implement it by default.
Outlets also note the government’s legal and technical framing: DoT changes the definition of Calling Line Identification (CLI) so it encompasses the operator-assigned identifier and the caller name recorded in subscriber records, rather than the number alone. Users are expected to retain options related to privacy through existing calling line identification restriction (CLIR), under which the caller’s name would not be shown. Several reports caution that the usefulness depends on the accuracy of operator records.
