What is DLT?
DLT (Distributed Ledger Technology) is a system where all messages sent using SMS routes must be recorded and verified. This is a rule set by TRAI (Telecom Regulatory Authority of India) to stop spam messages and fraud.
Every business that sends SMS to its customers has to register on a DLT portal. These portals are managed by telecom companies like Airtel, Jio, BSNL, Vodafone, and others. These companies are called DLT operators.

Why DLT is Important in India
DLT keeps customers safe by ensuring only approved messages are sent. Hereâs why DLT is needed:
- To stop spam messages đ”
- To protect your data
- To help only real businesses send SMS
- To follow TRAI rules and avoid fines
Without DLT, many people might receive fake offers, harmful links, or unwanted ads. With DLT, only trusted messages reach the phone!
TRAI Guidelines for DLT in India
The Telecom Regulatory Authority of India (TRAI) made DLT registration mandatory under the Telecom Commercial Communications Customer Preference Regulations (TCCCPR), 2018. This ensures that all SMS messages are sent only through verified businesses and approved templates.
