TRAI (Telecom Regulatory Authority of India) has introduced new rules for bulk SMS to protect consumers and bring more transparency to business messaging.
If your business sends promotional, transactional, or service SMS, these guidelines were made mandatory from October 1, 2024.
In this guide, learn how to comply with TRAI's bulk SMS regulations and how Arihant IT Solutions, a leading bulk SMS provider, can help you.
📌 New TRAI Bulk SMS Regulations 2024: Key Highlights
1. Bulk SMS Header (Sender ID) Registration is Mandatory
Businesses must register their SMS headers (also known as Sender IDs) on DLT platforms managed by telecom operators.
There are two main types:
-
Promotional Headers (6-digit numeric codes):
-
Example: 123456 (Banking/Insurance), 234567 (Real Estate), etc.
-
-
Transactional & Service Headers (6-letter alphabetic codes):
-
Example: HDFCOT (for OTPs), BANKTX (for alerts).
-
✅ Note: Sender IDs must represent your brand clearly. Generic or duplicate headers will not be approved.
2. SMS Content Template Registration with Variable Tagging
-
Every SMS you send must match a pre-approved template on DLT.
-
All dynamic fields (like customer names, OTPs, etc.) must be tagged properly.
-
Helps maintain transparency and prevent misuse of SMS templates.
3. URL and Callback Number Whitelisting is Now Compulsory
-
If your SMS contains URLs, APK links, OTT links, or phone numbers, you must whitelist them on the DLT portal.
-
Messages with non-whitelisted links will be automatically blocked by telecom operators.
4. PE-TM Chain for Bulk SMS Traceability
-
Businesses (Principal Entities - PE) must define their relationship with their Telemarketer (TM).
-
This helps track every message origin for security purposes.

Register your company as a Principal Entity (PE) on authorized DLT portals like Airtel, Jio, Vodafone-Idea, BSNL, Videocon etc.
