The Government of India has directed telecom operators to introduce a new caller identification system from November 1, 2026, under which mobile users will be able to see the caller’s registered name along with the phone number. The service, known as Calling Name Presentation (CNAP), aims to make it easier to identify unknown callers and improve transparency in telephone communications.
The new system will initially cover 4G and higher-generation mobile networks, including 5G. Users will not need to submit a separate request to activate the service. The rollout for 2G, 3G and landline networks will be considered separately.
The change could be particularly useful for people who frequently receive calls from unfamiliar numbers, including suspected spam calls, marketing calls and potential fraud attempts.
What Is CNAP (Calling Name Presentation)?
Calling Name Presentation, or CNAP, is a telecom-based caller identification service designed to display the name associated with a phone number in the telecom operator’s subscriber records.
Unlike caller identification applications that may rely on community reports or other databases, CNAP uses information maintained by the telecom service provider. The Department of Telecommunications (DoT) has directed operators to implement the service across their respective service areas from November 1, 2026.
The primary objective is to help recipients identify callers before answering, particularly when the number is not saved in their phone contacts.
How Will the New Caller ID System Work?
The CNAP service will operate through information exchanged between telecom networks.
Here is how callers’ names are expected to appear:
1. Number saved in your contacts
Your phone will generally display the name you have saved for that number.
2. Unknown domestic number
The caller’s name recorded in the originating telecom operator’s subscriber database will be displayed along with the number.
3. International call from an unsaved number
The display will show “International Call” instead of the caller’s name.

The caller identification information will be retrieved through the telecom operators’ systems. Operators must maintain databases linking subscriber names with their assigned telephone identifiers.
From Which Date Will Caller Name Display Become Mandatory?
The important implementation details are summarised below.

These details are based on the reported DoT instructions and official public broadcaster News On AIR.
Will CNAP Work on Jio, Airtel, Vi and BSNL?
The directive applies to telecom service providers holding the relevant authorisation or licences to provide access services. Accordingly, the implementation is intended to cover eligible services operated by major providers, including Reliance Jio, Bharti Airtel, Vodafone Idea (Vi) and BSNL, subject to the applicable network coverage and rollout arrangements.
However, users should distinguish between the announced implementation date and actual availability on every handset or network configuration. The initial rollout concerns 4G and higher-generation wireless networks; 2G, 3G and landline services are being considered separately.
Will CNAP Help Reduce Spam Calls and Online Fraud?
One of the major anticipated benefits of the new caller name display rule is improved caller transparency.
Many people receive unsolicited calls from individuals claiming to represent banks, insurance companies, loan providers, courier services or government departments. Displaying the subscriber’s registered name could help recipients make a more informed decision about whether to answer.
Potential benefits include:
- Better identification of unknown callers: Users may be able to recognise the name associated with an unfamiliar domestic number.
- Improved awareness: The displayed name and number provide additional information before a call is answered.
- Greater transparency: Callers may find it harder to rely solely on anonymity to establish trust.
- Convenience for ordinary users: People will not need to depend exclusively on third-party caller identification apps to obtain basic subscriber-name information.
However, CNAP should not be treated as a complete solution to telephone fraud. A displayed name is not proof that the caller is trustworthy. Fraudsters may use spoofed numbers, manipulated caller information or other techniques to mislead recipients. Users should never disclose an OTP, PIN, password or banking credentials merely because a caller’s name appears familiar.
Can Users Hide Their Names Under the New CNAP Rules?
The DoT instructions provide an important exception for subscribers who have activated the Calling Line Identification Restriction (CLIR) facility in accordance with the applicable guidelines.
For these subscribers, the calling name identity will not be displayed through CNAP.
This exception is relevant because the introduction of caller name display also raises questions about privacy and the protection of subscriber information.
Users should check with their telecom operator for information about the availability and conditions of any applicable calling-line privacy facility.
How Will CNAP Protect User Privacy?
The new framework includes safeguards for handling caller identity information.
According to the reported DoT instructions, telecom operators must adopt a security-by-design approach. The caller’s name obtained through the query-response mechanism must not be retained after the incoming call has ended. Operators must also ensure that their systems can retrieve and deliver caller identity information efficiently without compromising the quality of telecom services.
Telecom service providers are also required to establish a grievance redressal mechanism for complaints relating to the service.
These measures are intended to balance improved caller identification with data security, privacy and reliable network performance.
Can Businesses Display Their Company or Brand Names Instead of Personal Names?
Yes. The new arrangements provide for businesses and users with bulk connections to apply for the display of a preferred name, subject to verification requirements.
The preferred name must meet the prescribed registration criteria. According to the reported instructions, it must be either:
- A trademark registered in the applicant’s name with the Trade Marks Registry; or
- A trade name registered on the Goods and Services Tax (GST) portal.
Telecom operators must verify the relevant documents before approving the preferred name. Existing subscribers using business or bulk connections will have to apply to update their subscriber records through the operator’s prescribed process.
This provision could benefit legitimate businesses that communicate with customers by telephone, helping recipients identify registered business names rather than unfamiliar numbers alone.
Will CNAP Replace Truecaller?
CNAP and third-party caller identification applications serve related but different purposes.
CNAP is designed to display the caller’s name using telecom subscriber records. Applications such as Truecaller may offer additional features, including community-based spam identification, business information and user-reported warnings.
Therefore, CNAP may reduce the need to rely on third-party apps for basic caller-name identification, but it does not necessarily replace all their features.
It is also important to remember that the name displayed through CNAP is based on telecom subscriber records. It should not automatically be interpreted as a verified indication of the caller’s intentions, professional role or legitimacy.
What Should Mobile Users Do Before November 1, 2026?
Most users will not need to register separately or submit an activation request. The service is intended to be enabled by default for the initially covered networks.
Nevertheless, users can take the following precautions:
- Keep their SIM subscriber details and KYC information accurate.
- Check with their telecom provider if the caller name display feature does not appear after implementation.
- Avoid trusting unfamiliar callers solely because a name is displayed.
- Never share OTPs, banking PINs, passwords or other confidential information over an unsolicited call.
- Report suspected fraudulent calls through the appropriate official reporting channels.
- Businesses using bulk connections should review whether they qualify for a verified preferred business name.
Frequently Asked Questions (FAQs)
1. When will caller name display become mandatory in India?
The Department of Telecommunications has directed telecom operators to introduce CNAP from November 1, 2026.
2. Will I need to download an app to see a caller’s name?
No separate third-party application is required for the CNAP service. It is intended to operate through telecom networks and be enabled by default for users on covered networks.
3. Will the caller’s name appear for numbers not saved in my contacts?
Yes. For unsaved domestic numbers, the name recorded in the originating telecom operator’s subscriber database is expected to appear with the number.
4. Will the system work on 2G and 3G phones?
The initial rollout is for 4G and higher-generation wireless networks. Implementation on 2G and 3G networks will be considered separately.
5. Will international callers’ names be displayed?
For international calls from unsaved numbers, the display will show “International Call” rather than the caller’s name, according to the reported instructions.
6. Does CNAP guarantee that a call is genuine?
No. CNAP provides caller identity information based on telecom records, but it does not guarantee that a call is safe or that the person speaking is trustworthy.
7. Can businesses display a registered brand name?
Eligible businesses and bulk-connection users may apply to display a preferred name, subject to the applicable trademark or GST registration and verification requirements.
Conclusion
The mandatory caller name display initiative marks an important development in India’s telecom services. From November 1, 2026, the CNAP rollout is intended to make registered caller identities more readily visible to mobile users on 4G and newer networks.
The system could improve transparency, make unknown calls easier to assess and provide legitimate businesses with a clearer way to identify themselves. However, its effectiveness in reducing fraud will depend on implementation, accurate subscriber records, privacy safeguards and continued public awareness.
The most important takeaway for mobile users: a displayed caller name can help you decide whether to answer, but it should never replace basic precautions against telephone fraud.
