In a major step towards strengthening telecom security and tackling the growing menace of spam and fraudulent calls, Reliance Jio has rolled out its Caller Name Presentation (CNAP) service across several Indian states. The new feature is designed to display the verified, real name of the caller on the recipient’s mobile screen at the time of an incoming call, helping users instantly identify unknown numbers and reduce the risk of scams.
According to Jio, the CNAP service draws its data directly from the official, verified telecom database, using the name submitted by the subscriber at the time of SIM activation through Aadhaar or other Know Your Customer (KYC) documents. This marks a significant shift from third-party caller identification apps, which often rely on user-generated information and may display incorrect or misleading names.
How CNAP is different from Truecaller
While many smartphone users currently depend on applications such as Truecaller to identify unknown callers, telecom experts point out that CNAP operates on a fundamentally different model. Truecaller typically displays names saved by other users or tagged within its crowd-sourced database, which can sometimes result in inaccurate or manipulated caller identities.
CNAP, by contrast, is an operator-level feature, integrated directly into the telecom network. Because the displayed name is sourced from verified subscriber records, it is expected to significantly reduce the incidence of fake names, misleading spam labels and impersonation tactics frequently used by fraudsters. Industry observers believe this could restore a higher level of trust in voice calls, which has eroded in recent years due to rampant scam activity.
Rollout across multiple states
Reports indicate that Jio has already launched the CNAP service in several regions, including Bihar, Uttar Pradesh (East), West Bengal, Rajasthan, Punjab, Kerala, Assam, Jharkhand and Odisha. The rollout is being carried out in phases, with wider coverage expected over the coming months.
Other telecom operators, including Airtel, Vodafone Idea (Vi) and BSNL, are also working on introducing similar caller identification features. The nationwide implementation of CNAP has been directed by the Telecom Regulatory Authority of India (TRAI) as part of broader efforts to enhance consumer protection and transparency in telecom services.
Government warning on silent calls
Alongside the CNAP rollout, the Department of Telecommunications (DoT) has issued a fresh advisory warning users about so-called silent calls—calls in which there is no response when the recipient answers. According to the government, such calls are often made by scammers to verify whether a number is active before targeting it for fraud.
Authorities have advised users to block such numbers immediately and report them through the Sanchar Saathi portal, a government platform designed to help citizens report suspicious telecom activity. Officials say combining CNAP with increased public awareness could significantly reduce the success rate of telecom scams.
Impact on users and calling experience
Telecom analysts believe CNAP could play a crucial role in improving the overall calling experience in India, which has been severely affected by spam and fraudulent calls. By allowing users to see the real, verified name of the caller before answering, the service is expected to reduce anxiety associated with unknown numbers and empower users to make informed decisions.
Experts also note that CNAP could be particularly beneficial for elderly users and those less familiar with digital fraud patterns, as it adds a visible layer of identity verification at the most basic level of communication.
Privacy and implementation challenges
While the service has been largely welcomed, some privacy advocates have urged telecom operators to ensure that subscriber data is handled responsibly and displayed strictly in accordance with regulatory guidelines. Industry sources say safeguards are being put in place to ensure that CNAP balances user safety with data privacy, and that only essential identification information is shown.
As telecom fraud continues to evolve in sophistication, the introduction of CNAP represents a significant structural response by the industry. With nationwide implementation expected in stages, the service could mark a turning point in India’s fight against fake calls and impersonation, making voice communication more secure, transparent and trustworthy for millions of mobile users.
