TRAI Tightens Spam Rules With AI Detection And Appeals
TRAI has made rules stricter to reduce unwanted calls and messages.
Telecom companies will use artificial intelligence to find phone numbers that probably send spam.
If five or more numbers linked to one sender are flagged within 10 days, the company can investigate further.
Repeat offenders may have their customer information checked again or their services restricted.
They could eventually be disconnected.
Automated calls, robocalls, prerecorded calls, and artificial-voice calls must be declared to telecom companies beforehand.
Undeclared automated calls can be treated as unwanted commercial communication.
Some unauthorised automated calls may cost up to five paise per minute.
People can appeal decisions about spam complaints within 15 days through several available channels.
TRAI amended its unsolicited commercial communications framework to introduce AI-based spam detection and stricter enforcement.
Providers must share suspected spammer information, with five linked numbers flagged within 10 days triggering further checks.
Repeat offenders may face KYC or physical verification, outgoing-service restrictions, or disconnection.
Entities using automated, robocall, prerecorded, or artificial-voice calls must declare their numbers and systems in advance.
Consumers can appeal UCC complaint decisions within 15 days, while unauthorised A2P calls may incur charges of up to ₹0.05 per minute.
