How Caller Name Presentation Works from 1 November 2026"},"content":{"rendered":"\n

Have you ever hesitated to answer an unknown number because you did not know who was calling?<\/strong>
From 1 November 2026, mobile operators are directed to introduce Calling Name Presentation (CNAP) across 4G and higher-generation wireless networks. When you receive a call from a number that is not saved in your contacts, your phone may display the caller\u2019s name along with their number.<\/p>\n\n\n\n

CNAP works through the telecom network, so you do not need to install an app or make a separate request to activate it. The name shown comes from the caller\u2019s subscriber records held by their mobile operator.<\/p>\n\n\n\n

This guide explains how CNAP works, what information appears on your screen, how it differs from caller ID apps and what businesses need to know.<\/p>\n\n\n\n

What is CNAP?<\/strong><\/h2>\n\n\n\n
\"Example<\/figure>\n\n\n\n

CNAP Full form is Calling Name Presentation<\/strong>. It is a telecom network service that displays the caller\u2019s name on the receiver\u2019s phone during an incoming call.<\/p>\n\n\n\n

The name is taken from the caller\u2019s subscriber records maintained by their mobile operator. If the number is already saved in your contacts, your phone will show the name you saved. If it is not saved, the network can display the caller\u2019s name recorded by their operator.<\/p>\n\n\n\n

DoT has directed operators <\/a>to provide CNAP without requiring users to submit a separate request.<\/p>\n\n\n\n

Initially, it will be available on 4G and higher-generation wireless networks, including 5G<\/strong>. DoT will consider support for 2G, 3G and landline networks<\/strong> separately.<\/p>\n\n\n\n

Users will not need to request activation or install an app. CNAP is designed to work through the telecom network.<\/p>\n\n\n\n

How does CNAP work?<\/strong><\/h2>\n\n\n\n
\"Infographic<\/figure>\n\n\n\n

When a call is made, the caller\u2019s mobile operator checks the subscriber record linked to that number. The caller\u2019s operator makes the name available through the telecom network, and the receiving operator retrieves it for display on the receiver\u2019s phone.<\/p>\n\n\n\n

The name shown for an unsaved number is called the calling name identity<\/strong>. It is based on the name in the caller\u2019s subscriber records, which are generally linked to the details provided when the SIM connection was registered.<\/p>\n\n\n\n

Here is what you may see on your phone:<\/p>\n\n\n\n

Call type<\/strong><\/td>What may appear on your screen<\/strong><\/td><\/tr>
A number saved in your contacts<\/td>The name you saved<\/td><\/tr>
A domestic number not saved in your contacts<\/td>The caller\u2019s name from their operator\u2019s subscriber records<\/td><\/tr>
A call from outside India<\/td>\u201cInternational Call\u201d<\/td><\/tr>
A caller using CLIR<\/td>The caller\u2019s name will not be displayed<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

CLIR<\/strong>, or Calling Line Identification Restriction<\/a>, is a facility used to restrict the display of a caller\u2019s identity. DoT\u2019s circular says that the calling name identity of a user who has activated CLIR will not be presented.<\/p>\n\n\n\n

What does CNAP mean for privacy?<\/strong><\/h3>\n\n\n\n

To show a caller\u2019s name, the mobile network checks the subscriber records linked to that phone number and sends the matching name to the receiver\u2019s network. DoT requires this lookup system to be designed so that the name used for the CNAP response is not retained after the call ends.<\/p>\n\n\n\n

This requirement applies to the CNAP lookup process. It does not say that the subscriber record used to identify the caller is deleted. The circular also requires operators to maintain records linking users\u2019 names with their phone numbers.<\/p>\n\n\n\n

CNAP in India: Rollout Timeline and Key Dates<\/strong><\/h2>\n\n\n\n

Telecom authorities have discussed CNAP since 2022. Its rollout plan has developed over time\u2014from TRAI\u2019s initial recommendation to provide it on request to DoT\u2019s direction to make it available by default.<\/p>\n\n\n\n

On 23 February 2024, TRAI recommended<\/strong><\/a> that users should be able to request CNAP. On 26 September 2025<\/strong>, DoT asked TRAI to reconsider this approach and make the service a default feature. The following month, TRAI agreed to a default service with an opt-out option.<\/p>\n\n\n\n

Trials began in November 2025<\/strong>. Jio, Vodafone Idea and BSNL conducted trials in Haryana, while Airtel conducted trials in Himachal Pradesh. An earlier nationwide deadline passed in March 2026<\/strong> without full coverage.<\/p>\n\n\n\n

On 23 June 2026<\/strong>, telecom authorisation rules were notified under the Telecommunications Act, 2023. Rule 48 requires caller identification to be protected from tampering. Then, on 13 October 2026<\/strong>, DoT issued a circular directing operators to introduce CNAP on 4G and higher-generation wireless networks from 1 November 2026<\/strong>.<\/p>\n\n\n\n

Can users opt out of CNAP?<\/strong><\/h3>\n\n\n\n

In October 2025, TRAI agreed to a default service with an opt-out option. However, DoT\u2019s final circular requires operators to provide CNAP without a separate request and does not explain how users can switch it off. Contact your mobile operator for its latest instructions.<\/p>\n\n\n\n

CNAP vs caller ID apps<\/strong><\/h2>\n\n\n\n

CNAP and caller ID apps can both display a name for an incoming number, but they use different sources.<\/p>\n\n\n\n

CNAP gets the name from the caller\u2019s subscriber records held by their operator. Caller ID apps usually use their own databases, which may include information shared by app users. Caller ID apps may also provide features such as spam labels.<\/p>\n\n\n\n

What businesses need to know about CNAP<\/strong><\/h2>\n\n\n\n

For business or bulk connections, the name displayed by default is the name recorded in the connection\u2019s subscriber details. This may be a company\u2019s legal name rather than the brand name customers recognise.<\/p>\n\n\n\n

DoT\u2019s circular allows an operator to offer a preferred name<\/strong> for a business or bulk connection. The preferred name must be either:<\/p>\n\n\n\n
