If your business sends SMS to customers in India — offers, OTPs, reminders, anything — TRAI rules require you to register on a DLT (Distributed Ledger Technology) platform first. Without it, operators silently block your messages. This guide walks Odisha businesses through the whole process.
What is DLT and why does it exist?
DLT registration was introduced by TRAI to curb SMS spam and fraud. Every legitimate sender registers their business identity, sender IDs (the 6-character name customers see) and message templates on an operator-run DLT portal. Operators then only deliver messages that match a registered template from a registered sender.
Documents you need
- GST certificate (or Udyam/shop licence for unregistered businesses)
- PAN card of the business or proprietor
- Authorised signatory letter and ID proof
- Business address proof
The process, step by step
- Choose a DLT platform — Jio, Airtel, Vodafone-Idea or BSNL portals all work; registration on one is honoured by all operators.
- Register as a Principal Entity — submit your documents and pay the one-time registration fee. Approval usually takes 2-5 working days.
- Register your sender ID (header) — a 6-letter brand identifier like GURSMS.
- Register message templates — every promotional and transactional message format you plan to send, with variables marked as {#var#}.
- Link your telemarketer — connect your SMS provider (like Guru SMS) so campaigns route under your registered identity.
Common rejection reasons
Templates get rejected for vague variable usage, missing opt-out language in promotions, or mismatched entity names. A good SMS partner reviews your templates before submission — at Guru SMS we do this free for every client, and most of our Odisha clients complete the entire DLT process within a week.
