This guide covers the DLT (Distributed Ledger Technology) registration process required before any regulated voice or messaging traffic can go live in India - Principal Entity registration, header approval, and template approval. If you’re looking specifically to acquire a 140 or 160 series number, see the 140 & 160 Acquisition Guide - that guide covers the number-acquisition paths and links back here for the DLT steps each path depends on.

​
1. Overview

140 - Promotional Communication

Used for marketing, sales, and promotional offers. Requires strict DLT registration and opt-in consent.

160 - Transactional / Service
