I. Introduction to CNAP
This document outlines the development and implications of India’s new Calling Name Presentation (CNAP) system, a government initiative aimed at combating spam and fraudulent calls by displaying verified caller names.
- Problem: Relentless spam calls and deceptive telemarketers in India.
- Solution: The Modi government is rolling out the Calling Name Presentation (CNAP) system.
- Mechanism: Displays the Aadhaar-linked name or KYC verified name of callers on the recipient’s screen.
- Objective: To bring transparency to mobile communications, revolutionize spam call and fraudulent call protection, and address privacy concerns.
- Significance: A fundamental shift and an official alternative to popular third-party apps.
II. What is CNAP? A Verified Alternative to Third-Party Apps
While apps like Truecaller have served as shields using crowd-sourced data, they are unofficial and can have accuracy limitations. CNAP offers a verified, official alternative.
- Current Landscape: Apps like Truecaller act as shields using crowd-sourced data, but are unofficial and can have accuracy limitations.
- CNAP’s Approach: A DoT (Department of Telecommunications) initiative overseen by DoT and TRAI (Telecom Regulatory Authority of India).
- Data Source: Retrieves the caller’s registered name directly from telecom Know Your Customer (KYC) records, often tied to Aadhaar details.
- Primary Objectives:
- Enhance mobile communications transparency.
- Significantly reduce spam calls.
- Curb telemarketing activities.
- Provide robust scam protection.
- Call Display Logic:
- For unknown callers, displays the verified name.
- If the number is saved in contacts, it first flashes the Aadhaar-associated name, then switches to the saved contact name.
III. Technical Implementation of CNAP
CNAP is designed as a built-in feature within the telecom network, eliminating the need for separate user downloads.
Key Technical Aspects:
- Data Source: Pulls caller names from Calling Name (CNAM) databases maintained by individual telecom operators (Reliance Jio, Bharti Airtel, Vodafone Idea), linking subscriber names to phone numbers.
- Call Flow:
- Network identifies the originating network.
- Fetches the caller’s registered name from the relevant CNAM database.
- Pushes the verified name to the recipient’s device, likely superseding local contact names for unknown callers.
- Network Integration: A seamless, network-level feature, part of the core telecommunication infrastructure.
- Rollout & Compatibility:
- Initial trials in select regions: Haryana, Himachal Pradesh, Maharashtra.
- Nationwide rollout anticipated by March-April 2026.
- Primarily designed for modern 4G and 5G networks.
- Older 2G and 3G networks present technological challenges.
- Telecom giants collaborating with global technology companies for infrastructure.
- Default & Opt-Out:
- Expected to be activated by default for all users.
- A crucial opt-out feature will be available.
- Exemptions for users with Calling Line Identification Restriction (CLIR) service (e.g., government officials, whistleblowers) to preserve anonymity.
IV. Privacy Concerns and Data Protection
The implementation of CNAP sparks debates, particularly in light of India’s Digital Personal Data Protection Act, 2023.
Key Concerns:
- Consent Issues: Displaying personal names without explicit, informed consent is a major contention. Telecom operators and COAI advocate for an opt-in service.
- Risk of Data Aggregation and Misuse: Potential for handset manufacturers and OS providers to aggregate subscriber data, creating a centralized database vulnerable to breaches and misuse.
- Vulnerability of Specific Groups:
- Heightened risks for whistleblowers, journalists, and victims of abuse due to potential exposure to harassment, retribution, or threats.
- Concerns about women’s safety online, with fears of increased targeted sexual harassment.
- Accuracy and Identity Spoofing: The system may not be foolproof; multiple SIM registrations can lead to discrepancies between registered owner and actual user, allowing for some impersonation.
- Data Breach Accountability: Lingering questions about accountability in the event of data breaches or leaks from the CNAP database.
V. Stakeholder Impact
Consumers:
- Positive: Expected significant reduction in spam, scam, and fraudulent calls; accurate caller identification; restoration of trust; diminished reliance on third-party apps; boost for consumer protection.
- Negative: Core privacy concerns, potential loss of anonymity for vulnerable individuals; worry about increased call setup times and potential decline in service quality.
Telecom Operators:
- Challenges: Substantial investment in network and IT upgrades; higher operational costs; technical hurdles (increased signaling load, call latency impacts); compatibility with older networks; seeking clarification on displaying names for business/family connections.
- Role: Conducting trials, developing infrastructure, maintaining accurate CNAM databases.
Government (DoT & TRAI):
- Objectives: Enhance communication transparency, reduce spam/fraud, improve user safety via verified caller ID, align with Digital India initiative.
- Actions: Directing operators for implementation, overseeing pilot programs.
- Balancing Act: Balancing fraud reduction benefits with significant privacy concerns.
Third-Party Caller ID Apps (e.g., Truecaller):
- Impact: CNAP is a direct competitor offering an official, network-wide solution. Truecaller suggests CNAP would complement its service, but the competitive landscape will change. Truecaller also offers opt-out for enhanced search functionality.
VI. Global Perspective on Caller ID Systems
The drive for clearer caller identification and scam protection is a global phenomenon.
Examples:
- Numeracle (USA): Protects and brands caller ID for service providers, delivering verified names/logos to combat fraud and spoofing. Available on major US networks.
- CallGlobe: Offers privacy features for individual users in international contexts, providing a private number and masking identity.
- Verizon Call Filter (USA): Includes Caller Name ID, call screening, automatic spam blocking, and reporting of unwanted numbers.
- Truecaller’s Global Reach: Operates internationally, populating unidentified numbers. Offers an opt-out for users to exclude their names/numbers from discoverability, acknowledging global privacy laws.

VII. Conclusion: The Future of Calls
- Significance of CNAP: A significant stride towards mobile communications transparency and a more secure calling environment in India.
- Potential: Alleviate spam calls and enhance scam protection, with a nationwide rollout by March-April 2026.
- Core Challenge: Balancing the need for unsolicited commercial communications reduction and consumer protection with imperatives of caller ID privacy and data security.
- Key Debate: Opt-in service versus default opt-out feature will shape public trust.
- Outlook: Continuous dialogue and robust frameworks are essential to ensure that privacy and anonymity rights, especially for vulnerable populations, are not compromised while gaining peace from unwanted calls. India’s approach is being watched globally.
