If you’re planning to send Bulk SMS in India, the first and most important step is completing your DLT Registration. It’s a mandatory process by TRAI (Telecom Regulatory Authority of India) to ensure that every SMS you send is verified, legal, and spam-free. Understanding the documents required for DLT registration will save you time and prevent rejection. Whether you’re a business owner, school, hospital, or reseller, you must upload valid DLT registration documents like PAN, GST, and authorization letters before approval.

DLT (Distributed Ledger Technology) is the official platform where all message senders must register. It helps telecom operators verify senders, track message origins, and maintain compliance. In this guide, we’ll cover every DLT registration document required, the step-by-step application process, and how Kapsystem makes it quick and simple for your business.
What is DLT Registration?
DLT (Distributed Ledger Technology) is a secure, government-approved platform that tracks and verifies all SMS communications in India. Think of it as a digital record book that keeps every sender’s details, message templates, and sender IDs transparent and protected.
TRAI introduced the DLT system to prevent spam, fraud, and misuse of messaging channels. Without DLT registration, your messages will not be delivered to recipients. Completing the registration ensures your SMS campaigns are trusted, compliant, and reach every customer successfully.
In short, DLT registration is mandatory for every entity that sends bulk SMS in India.
Who Needs DLT Registration?
Every organization or individual that sends messages for business or informational purposes must complete DLT registration. This includes:
- Businesses and Startups – sending marketing or OTP messages to customers.
- Educational Institutions – notifying students and parents about events or results.
- Hospitals and Clinics – sending appointment and health reminders.
- Banks and Fintech Companies – delivering OTPs, alerts, and transaction messages.
- Government Departments – sharing official notices and public information.
- Bulk SMS Resellers or Aggregators – who manage message delivery for clients.
Essentially, if you want your SMS messages to be delivered legally and instantly, you must complete the DLT registration process using the correct documents.
Types of DLT Entities
There are three main types of DLT users:
- Principal Entity (PE): The brand or company that owns the content and sends SMS (like a school or a shop)
- Telemarketer (TM): A service provider like Kapsystem that sends SMS on behalf of the principal entity
- Header and Template Registrant: The one who applies for sender ID and message content approval
