If your business sends SMS messages to customers in India — whether for OTP, promotions, order updates, or alerts — DLT registration is mandatory as per TRAI (Telecom Regulatory Authority of India) regulations. Without DLT registration, your SMS campaigns will be blocked by telecom operators.
In this guide, we walk you through the complete DLT registration process — from choosing the right portal to registering your SMS templates — so you can start sending compliant messages without delays.
DLT stands for Distributed Ledger Technology. TRAI introduced the DLT framework in 2019 to curb unsolicited commercial communications (spam SMS) in India. Under this system, every business (called a "Principal Entity") that wants to send commercial SMS must:
Multiple telecom operators run their own DLT portals. You only need to register on one portal — your registration syncs across all operators automatically.
| Operator | Portal URL | Best For |
|---|---|---|
| Airtel | https://dltconnect.airtel.in/ | Most popular, easy UI |
| Videocon | https://smartping.live/ | Most popular, easy UI |
| Jio | https://trueconnect.jio.com/ | Fast approval |
| Vodafone-Idea (Vi) | https://www.vilpower.in/ | Vi customers |
| BSNL | https://www.ucc-bsnl.co.in/ | Govt entities |
Keep these documents ready before starting registration:
Go to your chosen portal (e.g., dltconnect.airtel.in). Click on Register as Principal Entity. Enter your business email, mobile number, and create a password.
Choose your entity type: Enterprise, Government, or Individual/Proprietorship. This affects which documents you'll need to upload.
Upload scanned copies of your PAN, GST certificate, and incorporation documents. Ensure files are clear and under 2MB each (PDF or JPG format).
A Sender ID is the name that appears on the recipient's phone (e.g., INFYRC for InfyReach Connect). It must be 6 characters for commercial SMS. Choose a name that clearly represents your brand.
Every SMS message format must be pre-registered. Use {#var#} for variable parts. Example:
Your OTP for login is {#var#}. Valid for 10 minutes. — INFYRC
Entity approval typically takes 2–5 business days. Template approval can take 24–72 hours. You'll receive confirmation via email and SMS once approved.
