The New Rule on the Block: What is CNAP?
The Telecom Regulatory Authority of India (TRAI) has greenlit the implementation of Calling Name Presentation, or CNAP. Unlike third-party apps that rely on crowdsourced, often unreliable data, CNAP is a network-level feature. It requires telecom operators
to display the name of the caller as it appears in their official Know Your Customer (KYC) records, which are collected when a SIM card is purchased. This means that when you receive a call, your phone will show the legally registered name of the person or business calling you, bringing a new level of transparency to voice calls.
A Response to a Digital Epidemic
This move is a direct response to India's massive and escalating problem with spam and fraudulent calls. Scams ranging from fake KYC update requests to digital arrests and investment fraud have become rampant. In the first nine months of 2024 alone, online financial scams cost Indians nearly ₹11,333 crore. Fraudsters have long exploited the anonymity of unknown numbers, often using sophisticated techniques like spoofing international calls to appear as local numbers. By replacing anonymity with verified identity, CNAP aims to make it significantly harder for scammers to deceive their targets.
Part of a Bigger Playbook
CNAP doesn't operate in a vacuum. It is the latest addition to a comprehensive, multi-layered anti-fraud strategy. This includes the Sanchar Saathi portal, a citizen-centric initiative that allows users to manage their mobile connections and report stolen devices. A key feature of this portal is 'Chakshu', which enables citizens to proactively report suspected fraudulent communications received via call, SMS, or WhatsApp. Furthermore, the government has established the Digital Intelligence Platform (DIP) and a Financial Fraud Risk Indicator (FRI) to facilitate real-time intelligence sharing between law enforcement, banks, and telecom companies, helping to block fraudulent transactions before they are completed.
The Privacy Debate
While the primary goal is security, the rollout of mandatory caller ID has sparked a significant debate about privacy. Critics and civil society groups have raised concerns that making names public by default could expose vulnerable individuals, such as activists, journalists, or victims of abuse, to harassment or risk. There are also concerns about women's safety, with fears that mandatory name display could lead to increased stalking or unwanted contact. The government has argued that an existing feature, Calling Line Identification Restriction (CLIR), allows users to hide their number, but this is tightly controlled and not widely available to the general public. Proponents, however, argue the security benefits of fighting rampant fraud outweigh these concerns.
Challenges in Implementation
Beyond privacy, there are practical hurdles. One major challenge is database accuracy. A single person can legally own up to nine SIM cards, meaning the registered owner may not be the actual user, potentially leading to incorrect name displays. Telecom operators have also flagged technical issues, noting that implementing CNAP will require significant network changes and may not be compatible with older 2G/3G networks and many feature phones still in use across the country. Despite these challenges, the Department of Telecommunications (DoT) has pushed for CNAP to be enabled by default for all subscribers, with an option for users to opt-out if they choose.
