Introduction
The Department of Telecommunications (DoT) has directed telecom operators to implement Calling Name Presentation (CNAP) across service areas from November 1, 2026. The initiative seeks to make caller identification easier and reduce fraudulent calls. However, it also brings questions about personal privacy, the reliability of subscriber information and the misuse of caller details.
What Is CNAP and How Does It Work?
Calling Name Presentation (CNAP) is a telecom facility that shows a caller’s name along with their phone number on the recipient’s screen. If the number is already saved, the recipient’s contact name may appear. For an unsaved number, the system can display the name linked to the subscriber’s telecom records. Unlike third-party caller identification apps, CNAP uses information maintained by telecom service providers.
What Does the DoT Directive Provide?
Through its circular dated October 13, 2026, the Department of Telecommunications directed access service providers to introduce CNAP across service areas from November 1. The facility is intended to be activated by default, without requiring users to request it. The initial implementation covers wireless networks operating on 4G and newer technologies. The department has indicated that extending the service to 2G, 3G and landline connections will be considered separately.
What Is the Legal Framework Behind CNAP?
The regulatory framework includes the Telecom Regulatory Authority of India Act, 1997. Section 11(1)(a) empowers TRAI to make recommendations on telecommunications matters. TRAI recommended CNAP in February 2024, after which the Department of Telecommunications issued directions for implementation through the telecom licensing framework. The November 2026 rollout follows the department’s October 13 circular.
Can CNAP Help Reduce Cyber Fraud?
CNAP may help people assess unknown calls before answering them. Showing a name associated with a registered subscriber can make certain impersonation attempts easier to question and reduce reliance on third-party applications. However, the displayed name alone cannot confirm who is actually speaking or establish that a call is genuine. Users must continue to protect their OTPs, banking credentials and other sensitive information.
What Are the Privacy Implications?
Displaying a subscriber’s name to call recipients raises questions about the balance between fraud prevention and individual privacy. In Justice K.S. Puttaswamy (Retd.) v. Union of India (2017), the Supreme Court recognised privacy as a fundamental right under Article 21 of the Constitution. This does not automatically render CNAP unconstitutional, but its implementation must respect applicable legal requirements and privacy safeguards.
The CNAP framework provides that subscribers using Calling Line Identification Restriction (CLIR) will not have their names displayed. It also adopts a security-by-design approach intended to prevent the caller’s name from being retained through the name-query process after the call ends. Despite these safeguards, the accuracy of subscriber records and the possibility of misuse remain important concerns.
Can Businesses Display a Different Name?
Eligible business and bulk-connection subscribers may be allowed to display a preferred name instead of the name recorded in their subscriber application. The name must satisfy the applicable requirements, such as being a registered trademark or a trade name registered on the GST portal. Telecom operators are required to verify the supporting documents. This process can help recipients recognise legitimate business calls while reducing unauthorised use of business identities.
What Are the Legal Limitations of CNAP?
CNAP can assist with caller identification, but it cannot guarantee protection against fraud. A displayed name may be incorrect, outdated or linked to a subscriber who is not making the call. Nor does the displayed information, by itself, establish criminal intent or liability. Allegations involving impersonation, cheating or cyber fraud must be examined on their facts under applicable laws, including the Bharatiya Nyaya Sanhita, 2023, and the Information Technology Act, 2000, where relevant.
Conclusion
The introduction of CNAP represents a significant step in India’s efforts to improve telecom transparency and address fraudulent calls. Its success will depend on accurate subscriber records, effective complaint mechanisms and safeguards against misuse. Caller identification can strengthen public confidence, but a displayed name must not be treated as conclusive proof of identity. The challenge is to improve call security while protecting the privacy and rights of subscribers.
