TRAI tightens commercial communication rules with AI spam detection and A2P call controls
TRAI has issued the Telecom Commercial Communications Customer Preference (Third Amendment) Regulations, 2026. Operators must flag likely spam numbers using AI/ML, automated A2P calls must be declared in advance, misused headers must be suspended within six hours, and businesses may contact enquirers for only seven days.
What happened?
On 18 September 2026 TRAI introduced the Telecom Commercial Communication Customer Preference (Third Amendment) Regulations, 2026, TelecomLead reported. Telecom operators must identify phone numbers with a high probability of sending unsolicited commercial communication and share that information with each other. Application-to-person (A2P) calls, meaning autodialled, robo or pre-recorded calls, must be declared in advance to the telecom provider along with the numbers used. Undeclared A2P calls are treated as spam. Terminating operators may charge up to ₹0.05 per minute for A2P calls, with exemptions for regulated commercial number series. Enforcement thresholds are lower. Three unique complaints in 10 days plus an AI/ML flag can now trigger action, down from five. Misused SMS headers or templates must be suspended within six hours. After an enquiry, a business may send commercial communication for only seven days, and the enquiry must be recorded in a verifiable form.
Why it matters for businesses
Indian businesses depend on SMS, IVR and outbound calls for OTPs, reminders and lead follow-up. These rules raise the compliance stakes. Autodialler and robocall campaigns now need formal declaration, a seven-day window limits follow-up on enquiries, and complaints can trigger action sooner. Sales-heavy sectors such as real estate, education, insurance and clinics need to update their calling and SMS processes, or they risk number barring and disconnection. The rules also stop call-management apps from blanket-blocking regulated commercial series like 140xx and 1600xx.
How businesses can use this update
- Check with your telecom or SMS provider that every automated or pre-recorded calling campaign is declared, with the numbers it uses. - Record every customer enquiry with a date and time in your CRM, so you can show that follow-ups fall within the allowed window. - Audit DLT headers and templates for misuse, and set up a process to respond within hours if a header is compromised. - Move promotional follow-ups to opt-in channels such as WhatsApp templates or email, where customers have clearly agreed to hear from you.
Pacewalk expert note
Compliance is now part of lead management. Every enquiry should be stored with its source and timestamp, and follow-up sequences should be designed around consent and time limits. Check the final text and effective dates on TRAI's website or with your provider before changing campaigns, since this summary is based on trade press coverage of the regulations.
