What is TRAI and DLT in Bulk SMS?

What is TRAI?

TRAI (Telecom Regulatory Authority of India) is the government body that regulates telecom services in India. To control spam, fraud, and unsolicited messages, TRAI has made strict rules for Bulk SMS communication.

TRAI ensures that:

• Customers are protected from spam messages

• Businesses send SMS in a transparent and compliant manner

• Only registered and verified entities can send Bulk SMS

What is DLT?

DLT (Distributed Ledger Technology) is a blockchain-based system introduced under TRAI regulations. It is mandatory for all businesses sending Bulk SMS in India.

DLT helps in:

• Verifying genuine businesses (entities)

• Registering approved Sender IDs

• Approving SMS content templates

• Preventing SMS fraud and misuse

Without DLT registration, Bulk SMS delivery is not allowed in India.

Why is DLT Registration Mandatory?

DLT registration is mandatory to:

• Stop spam and phishing SMS

• Ensure message transparency

• Protect end customers

• Maintain high SMS delivery rates

Only DLT-approved Sender IDs and templates are allowed to be delivered by telecom operators.

What Happens if DLT is Not Done?

• ❌ SMS delivery will fail

• ❌ Messages will be blocked by operators

• ❌ Risk of account suspension

• ❌ Non-compliance with TRAI guidelines
