DoT Orders Caller Name Display Rollout From 1 November on 4G and Newer Networks
The CNAP service will use telecom subscriber records to identify incoming callers, while saved contact names will continue to take priority.
The Department of Telecommunications (DoT) has directed telecom operators to introduce caller name display through the Calling Name Presentation, or CNAP, service from 1 November 2026.
The circular, dated 13 October 2026, applies across all service areas on wireless networks using 4G and newer technologies. Operators must provide the service without requiring a separate request from users.
For mobile subscribers, the intended change is straightforward: an incoming call from an unsaved domestic number can arrive with the name recorded by the caller’s telecom provider, alongside the number.
How Caller Name Display Will Work
CNAP connects caller identification with the subscriber information held by telecom operators.
The operator handling the outgoing call maintains a database linking subscriber names with telephone numbers. The operator receiving the call retrieves the relevant name and presents it to the person being called.
This approach makes the telecom subscriber record central to identification. It also makes the accuracy of that record important: the displayed name reflects the registered connection, rather than independently confirming who is speaking.
For example, recognising a subscriber’s name may help someone decide whether to answer an unfamiliar number. The information still needs to be understood in the context of the conversation.
What Name Will Appear on Your Phone?
The display follows an order of preference:
| Type of incoming call | Name or label to be displayed |
|---|---|
| Number already saved in your contacts | The name saved on your phone |
| Unsaved domestic number | The name recorded by the caller’s telecom operator |
| Unsaved international number | “International Call” |
| Caller using an eligible CLIR facility | The caller’s name will not be presented |
CLIR stands for Calling Line Identification Restriction. The exception applies to users who have obtained that facility under existing guidelines.
A saved contact therefore remains useful. If you have stored a person’s number under a familiar name or nickname, that label takes priority over the network-provided name.
Which Networks Are Covered?
The initial requirement covers 4G and higher-generation mobile networks, including 5G.
DoT has said that CNAP on 2G, 3G and fixed-line telephone networks will be considered separately. The circular does not give those networks a rollout date.
That distinction is important when interpreting the announcement. It establishes a nationwide obligation across the specified networks, rather than confirming that every telephone connection will support the feature on the same day.
The circular also does not provide a handset-by-handset compatibility list. Subscribers seeking confirmation about a particular device or connection will need information from their operator.
Do Users Need to Apply or Download an App?
Users are not required to submit a separate request for CNAP under the directive.
The service is designed to operate through telecom networks, and the circular does not require users to install a separate caller-identification application.
This could make caller-name information available to people who have never used an independent caller-ID app. However, the announcement concerns name presentation; it does not establish that CNAP includes every feature offered by such applications.
The practical benefit is additional information at the point when a user decides whether to answer a call.
Businesses May Display a Verified Preferred Name
The circular allows operators to offer eligible business and bulk connection holders a preferred display name.
That name must be either a trademark registered in the user’s name or a trade name registered on the GST portal, with prior verification by the telecom operator.
For new connections, supporting documentation and the preferred name must be recorded as prescribed. Existing connection holders must be given an application mechanism for verification and updating their records.
For a business, this could make an outgoing call easier to recognise. A customer expecting a delivery update or service appointment may find a familiar business name more informative than an unfamiliar number.
The commercial benefit will depend on accurate records and proper verification. A recognised name can improve identification, but it does not guarantee that a recipient will answer.
Privacy, Service Quality and Complaints
DoT requires operators to design the name-query process so that the calling name is not retained through that mechanism after the incoming call ends.
The requirement concerns the query process. Operators must still maintain the subscriber database used to provide the service.
They must also support timely name retrieval and maintain service quality.
The circular requires a time-bound grievance mechanism for CNAP complaints. If an incorrect name appears against a subscriber’s connection, the practical starting point is the relevant operator’s customer-support process.
The directive does not prescribe a specific number of days for resolving every complaint or publish a universal correction form.
Why the Government Has Pursued CNAP
The policy has developed through consultation and technical assessment over several years.
TRAI issued recommendations on CNAP on 23 February 2024. Its analysis described a familiar problem: reluctance to answer unknown numbers can cause legitimate calls to go unanswered, alongside concerns about unwanted and fraudulent calls.
A further TRAI response on 28 October 2025 recorded DoT’s position favouring availability by default and prioritising implementation on 4G and newer networks.
In an August 2026 parliamentary reply, the government described CNAP’s purpose as helping users make more informed decisions when responding to calls. It also noted technical limitations affecting existing 2G networks.
The October circular now specifies the rollout date and operating conditions.
What Caller Name Display Can—and Cannot—Establish
CNAP supplies another piece of identity information when a call arrives. Its value is in helping users recognise the connection behind an unfamiliar number.
A displayed name does not independently establish the caller’s intentions or validate a request for money, credentials or confidential information.
For operators, the practical test will be whether names appear accurately and promptly, including when calls cross networks. For users and businesses, effective complaint handling will matter when subscriber details are incorrect or outdated.
