Airtel DLT Registration Process

This guide is for businesses registering on Airtel DLT to send OTP, transactional, service, or promotional SMS in India as per TRAI guidelines.
What Is Airtel DLT Registration?
Airtel DLT registration is the process of registering your business principal entity ID on Airtel’s Distributed Ledger Technology (DLT) platform to send commercial SMS in India.
It is mandatory under TRAI regulations for sending transactional, promotional, service and OTP SMS.
Businesses can create principal identity, register Sender IDs (Headers) and get message templates approved on a blockchain-based system.
This ensures that only authorized and verified businesses can send SMS and prevent spam and fraudulent messages.
Your Entity ID, Headers, and Templates are automatically synced across other telecom operators. It allows you to send SMS nationwide without registering separately on each platform.
Documents Required for DLT Registration in India
To complete DLT registration in India, businesses must submit basic documents to verify identity, address, and authorization. Requirements may vary slightly based on business type (Individual, Proprietorship, or Private Limited), so it’s best to keep soft copies of all documents ready for online upload.
