The Telecom Regulatory Authority of India (TRAI) has updated its rules governing unsolicited commercial communications, commonly known as spam messages and calls. The Ministry of Communications announced these changes on 18 September 2026 through the Telecom Commercial Communication Customer Preference (Third Amendment) Regulations, 2026. The new framework affects telecom service providers, businesses sending commercial messages, telemarketers, and all mobile phone users across India.
Key Changes in the New Rules
TRAI has introduced ten major amendments to tackle spam more effectively.
- AI-powered detection: Telecom providers must now use artificial intelligence to identify phone numbers likely sending spam. When five or more numbers linked to a sender are flagged within ten days, the provider will investigate and may cut off their services. Legitimate commercial numbers in series 140xx, 1600xx and 1601xx will not be flagged as spam.
- Automated calls regulated: Businesses using automated calling systems (robo-calls and voice bots) must inform their telecom provider in advance. Calls made without this declaration count as spam. A charge of up to 0.05 rupees per minute applies to such calls.
- Inquiry-based messages: Companies can send follow-up messages for seven days after a customer asks about their product or service, provided the inquiry was written or sent digitally and kept as proof.
- Consumer appeals: People can now challenge decisions on their spam complaints within 15 days to an appeals authority.
- Faster action on complaints: Action against spammers can now begin with just 3 complaints within ten days (instead of 5), if the telecom provider’s AI system also flags that number as suspicious.
- Legacy consent recognition: Old permissions companies obtained from customers can now be registered digitally and accepted as valid consent.
- Template misuse penalties: If a telemarketer misuses message templates, all their telecom services across providers get disconnected for one year and they are blacklisted.
- App restrictions: Call management applications cannot automatically block legitimate commercial numbers designated by the government, though users can still block calls individually.
- Virtual operator access: Virtual network operators will get direct digital access to the registration platform to meet their obligations.
- Sender classification: TRAI may group senders into categories and apply different enforcement rules to each.
What This Means for You
If you receive spam calls and messages, the new system aims to detect and stop them faster using technology. You can now appeal if a complaint you filed was resolved unsatisfactorily, and you have multiple ways to report spam through apps and phone calls. Legitimate business messages, such as delivery updates or service notifications, should reach you without being blocked, though you retain the right to block any call on your own phone. The overall effect is stricter penalties for spammers and faster action against repeat offenders.
