India could get official caller ID by March 2026: What is CNAP and how does it work

This is a huge step from the current Calling Line Identification feature, which only displays the number of the caller and not the name. Since it is also a network-level caller ID solution, operators will also be able to exchange information amongst each other or make use of a centralised database to identify callers. CNAP might also come in handy to combat spam, as users will know if the person calling them is an individual or a business.

In a draft proposed in 2022, the regulatory authority suggested that users would have the option to enrol in CNAP, but now TRAI may be planning to enable CNAP for everyone unless they explicitly opt out by contacting their respective service provider. Implementation details are still being finalised, but TRAI is reportedly considering a centralised database with local copies maintained by network operators. Rolling out CNAP may also require infrastructure upgrades and greater data sharing among telecom providers.

Vodafone Idea, the third-largest network operator in India, has reportedly started CNAP’s pilot run in the state of Haryana, while Jio is expected to soon start its trial run in the state. However, the new caller ID system will initially be available only on 4G and 5G devices, meaning around 200 million people who are still reliant on 2G networks won’t be able to use it. Still, the implementation of CNAP will be a huge win for consumers, as it will most likely not require an active internet connection.

As for telemarketers, toll-free numbers and bulk users, CNAP will most likely display the company and organisation names, while those who purchase in bulk may have the option to choose a preferred name.
