DLT for SMS: Revolutionizing Business Messaging Compliance
With Focus on India’s TRAI DLT Regulations
What is DLT in SMS?
DLT (Distributed Ledger Technology) in SMS refers to a blockchain-based system that:
- Registers telecom entities (brands, carriers, aggregators)
- Stores approved message templates
- Tracks consent (opt-in/opt-out)
- Prevents spam via immutable audit trails
Key Example: India’s TRAI DLT mandate (2021) requires all business SMS to be registered on DLT platforms.
How DLT Works for SMS (Step-by-Step)
Entity Registration
- Businesses register with telecom operators via DLT portal.
- Get unique Principal Entity (PE) & Header IDs.
Template Approval
- Submit SMS content templates (e.g., OTP, promotional).
- Carriers approve/reject based on compliance.
Consent Management
- Store customer opt-ins on blockchain (phone number + purpose),
- Mandatory for promotional SMS.
Message Routing
Only DLT-approved templates are delivered.
Real-time spam scoring by carriers.
Audit & Reporting
- Immutable logs of all SMS sent.

India’s DLT SMS Requirements
