Comprehensive integration tracking parameters regarding TRAI Distributed Ledger guidelines across regional commercial network channels.
DLT (Distributed Ledger Technology) is a compliance platform set up by TRAI (Telecom Regulatory Authority of India) to regulate commercial SMS. Every business sending promotional or transactional messages in India must register on DLT and get approval for their sender IDs and message templates before sending.
Per explicit statutory TCCCPR mandates, enterprise distribution agents are strictly required to authorize corporate identity elements, lock branded headers, and clear system content templates down the central carrier index prior to initiating production loops.
Sign up on your telecom operator's DLT portal (Jio, Airtel, Vodafone, BSNL) with PAN, GST, and business identity documents.
Receive your Principal Entity ID after verification. This usually takes 1–2 business days.
Register a 6-character alphabetic sender ID (e.g., DUOTCH) linked to your brand.
Write your SMS templates for promotional, transactional, or service categories and submit for DLT approval.
Link your PE ID, sender ID, and templates to your Duotech account so you can start sending SMS right away.
DLT registration typically takes 2–5 business days. We handle the entire process for you — just submit your documents and we'll take care of the rest.
Our operational groups handle verification tasks across the telecom ledger completely. Avoid systemic registration roadblocks with zero configuration overhead.
