DLT Registration & TRAI Compliance

Everything you need to know about DLT registration in India — from Principal Entity setup to template approval. We handle the paperwork.

Overview

What is DLT?

Distributed Ledger Technology (DLT) is a blockchain-based platform mandated by TRAI (Telecom Regulatory Authority of India) since 2021. Every business sending commercial SMS in India must register on a DLT portal operated by telecom operators.

The registration ensures traceability of SMS messages, prevents spam, and protects consumers. Non-compliance results in messages being blocked at the operator level.

Why DLT Matters

  • Mandatory: Required for all commercial SMS in India
  • Blocking: Non-DLT messages are rejected by operators
  • Spam Prevention: Protects consumers from unsolicited SMS
  • Traceability: Every message linked to a registered entity
  • Template Matching: Messages must match approved templates
Step by Step

DLT Registration Process

We guide you through every step — or handle it entirely on your behalf.

1

Entity Registration

Register your business as a Principal Entity (PE) on the DLT portal of your preferred operator (Jio, Airtel, BSNL, Vi).

2

Sender ID (Header)

Register your 6-character Sender ID (header) that recipients will see, e.g., YOURID. Both transactional and promotional headers.

3

Template Approval

Submit your message templates with variable placeholders. Each template gets a unique DLT Template ID used when sending.

For promotional SMS, register consent templates and maintain opt-in records as required by TRAI regulations.

FAQ

DLT Registration FAQs

How long does DLT registration take?
Entity registration typically takes 3–5 business days. Sender ID registration takes 1–2 days. Template approval usually completes within 24–48 hours. With our assistance, the entire process can be completed in under a week.
Which DLT portal should I register on?
You can register on any operator's DLT portal — Jio DLT (Vilpower), Airtel DLT, BSNL DLT, or Vi DLT. Registration on one portal is valid across all operators. We recommend Jio's Vilpower for the smoothest experience.
What happens if I send without DLT registration?
Messages sent without valid DLT registration will be blocked by telecom operators. The message will never reach the recipient's phone. This applies to both transactional and promotional SMS.
Can OnlineSMSService handle DLT registration for me?
