What the circular does
A Department of Telecommunications (DoT) circular dated 13 October 2026 orders operators to present callers' registered names by default on 4G and 5G networks from 1 November 2026. The name comes from the operator's subscriber records. It appears when the recipient has not saved the caller's number. Operators must provide the service "without the requirement of any separate request from such user," MediaNama reports. Names are withheld only for subscribers who hold the calling line identification restriction (CLIR) facility. Since 2015, CLIR has been limited to VIPs and government officials, and other users need a recommendation from senior police officers. Unsaved international callers show as "International Call", and businesses can display a verified trademark or GST-registered trade name. The circular covers 4G and 5G only. 2G, 3G and landlines are left for separate examination.
The strongest case for the mandate
The case for the policy is real. Spam and fraud calls are a daily nuisance in India, and many people answer unknown numbers because the cost of missing a legitimate call is high. Apps such as Truecaller fill the gap with crowdsourced names that can be wrong or manipulated. A network-level service drawing on KYC records is harder to spoof, and it needs no third-party app. TRAI also argued that a name display only helps if scammers cannot opt out of it, which is a fair design point. A voluntary scheme that fraudsters simply decline protects nobody.
That argument, however, supports a narrower conclusion than the one DoT drew.
How the opt-out disappeared
TRAI's February 2024 recommendations proposed Calling Name Presentation (CNAP) as a supplementary service offered to subscribers on request. They followed a consultation paper issued in November 2022 and comments from 40 stakeholders. According to MediaNama, DoT pushed back in September 2025 and asked for a default service, with users able to ask their operator to disable it. TRAI then accepted a default model with an opt-out, in a response dated October 2025. The final circular kept the default and dropped the opt-out. The regulator's last position therefore did not survive in the order.
This matters because the opt-out was the compromise. A default with an off switch is already a significant concession to enforcement. A default with no switch, apart from a restriction facility rationed to officials, converts a service into a disclosure obligation on every subscriber.
Why CLIR is not an exit
On paper CLIR is the safeguard. In practice it is not available. The Internet Freedom Foundation noted in 2024 that CLIR requires police approval and periodic renewal, and that awareness of it is low. It concluded that CLIR cannot serve as a practical way to opt out of CNAP. Those who have the strongest reasons to withhold their names are the ones the current rules exclude. They include domestic-violence survivors calling a helpline, journalists contacting sources, and patients phoning a clinic. A person who calls a stranger back from a personal SIM now hands that stranger a legal name.
The harm is not hypothetical. A name plus a number is enough to find someone online. The disclosure happens to people who never chose it, on every call to a recipient without the number saved.
Missing guardrails
The circular requires operators to keep a number-to-name database, and it requires that names not be retained after each call ends. ThePrint reports that the circular does not address handsets. MediaNama notes that it does not explain how non-retention will be verified. It also does not mention the Digital Personal Data Protection Act, 2023, or caller consent, and it sets no grievance timeline. IFF warned in 2024 that shared name databases increase breach and misuse risk, and that CNAP should follow a rights-respecting data protection regime and an independent assessment of its privacy impact.
The legal basis also deserves scrutiny. The order rests on Rule 48 of the Telecommunications (Authorisation for Provision of Principal Telecommunication Services) Rules, 2026, which requires caller identification presented "in a manner that is secured from tampering," and on a Unified Licence condition. A rule about tamper-proof caller identification does not obviously authorise displaying a person's legal name to anyone they ring. If the order is challenged, the question is likely to be proportionality: whether the least intrusive effective means was chosen. TRAI's own earlier design suggests it was not.
A proportionate alternative
The fix is cheap and keeps most of the anti-fraud value:
- Restore a free, simple opt-out for individual subscribers, as TRAI accepted in October 2025.
- Make name display non-optional for business and bulk connections, where the fraud risk sits and the privacy interest is weak.
- Replace the police-recommendation gate for CLIR with a self-service restriction for sensitive use cases such as helplines and shelters.
- Publish an audit mechanism for the non-retention rule and the operator databases, and tie the service to DPDP Act obligations.
This approach would also treat the 4G/5G rollout as a pilot with a review point, since 2G, 3G and landlines are still to be decided.
India's telecom regulator did the careful work, and then the order that took effect discarded the part that protected individuals. Fighting spam is a legitimate goal. A mandate with no exit for ordinary users is not the proportionate way to pursue it, and it creates a new privacy risk of its own.
