TCCCP / TRAI regulations
The TCCCP regulations (TRAI’s Telecom Commercial Communications Customer Preference Regulations) are India’s rules for commercial calls and messages: the framework behind DND, telemarketer registration and the 140 series, aimed at unsolicited promotion, not relationship calling.
Definitions checked 2 September 2026.
TCCCP is the Telecom Commercial Communications Customer Preference Regulations, TRAI's rulebook for commercial calls and messages on Indian telecom networks. It is the framework behind everything else in this section: the DND register that lets subscribers refuse promotion, the registration of telemarketers and of the businesses (principal entities) that use them, the DLT platforms on which SMS headers and templates are registered, the 140 number series for promotional voice calls, and the complaint and penalty process that operators run.
Its target is unsolicited commercial communication, promotion pushed at people who have no relationship with the sender. It is not aimed at a business calling its own enquiries and customers about their own business, which the regulations treat as ordinary communication. This distinction is the most misunderstood thing in the category, because vendors selling registration services have an interest in making every business calling its customers feel it needs a licence.
What a small business calling its own leads should take from TCCCP: do not buy or scrape lists, honour do-not-call requests instantly, keep a record of where each lead came from, and if you ever move into cold promotional calling, register and use the 140 series. WhatsApp sits outside TCCCP entirely; it answers to Meta's policy and the DPDP Act. RMDialer, which we make, is built for the relationship side: a dialer for calling people who asked, from your own number, with the source and consent on the record.
