Here is a situation many first-time senders run into. The message looks perfect, the contact list is ready, and the send button is clicked. Then nothing arrives. No error, no warning, just silence. In India, the most common reason is that the business never completed DLT registration.
If you are new to the idea, the guide on what is DLT registration in India from MetaReach Marketing explains the whole process in detail. This article gives you the short, practical version first.
So, What Is DLT?
DLT stands for Distributed Ledger Technology. TRAI, the telecom regulator, uses it as a framework to keep commercial SMS under control. Businesses register their identity, their sender names and their message formats. Telecom operators then check every outgoing commercial message against those records. If a message does not match, it can be blocked before it reaches anyone. The goal is simple: cut down on spam and fraud.
The Three Things You Register
- Entity: your business identity. Once verified, you receive a unique Principal Entity (PE) ID.
- Header: the short sender name people see, such as a brand abbreviation. Each header is tied to a message category.
- Template: a pre-approved message with fixed text and variable fields, usually marked with a placeholder such as {#var#}.
Your SMS provider also needs to be linked to your entity. This step is often called PE-TM binding, where the provider acts as the telemarketer on your behalf.
How the Process Usually Works
The steps are fairly straightforward once you see them in order:
- Pick a DLT portal run by a telecom operator, such as Jio, Airtel or Vi.
- Register your business entity and upload the required documents.
- Add your sender IDs as headers, matched to the right category.
- Submit your message templates for approval.
- Link your SMS provider to your entity.
- Send campaigns using only approved headers and templates.
Typical documents include business PAN, a GST certificate if you have one, proof of registration, and an ID for the authorised signatory. Sole proprietors generally use personal ID documents. Requirements can differ by portal, so check before you start.
