How to Register on TRAI DLT Portal for Bulk SMS in India
1Principal Entity registration
Register the business or legal entity as a Principal Entity through an access provider DLT portal, following that provider's current identity and authorization requirements.
2Header registration
Request an approved header for commercial communication. The header format, category, supporting evidence, and approval remain subject to the access provider and current TRAI rules.
3Content-template registration
Register the fixed and variable structure of each intended message as a content template linked to the approved sender and header.
4Consent setup where applicable
Register the applicable consent-template structure and acquire recipient consent where the communication category and current rules require it.
5Delivery configuration and testing
Configure the provider workflow to transmit the required Principal Entity ID, header, and content-template ID, then test matching, opt-out handling, and failure reporting before launch.

3. Message Scrubbing & Delivery
The selected messaging provider should transmit the required identifiers and report template-matching or delivery failures. A successful DLT match does not by itself establish recipient consent, delivery, or legal suitability for every use case.
