What Is the DLT Registration Process?

DLT Registration Process means that you register your business and messaging assets with a Distributed Ledger Technology platform authorized by TRAI.

These platforms keep an immutable ledger of:

• Business entities
• Sender IDs (headers)
• Message templates
• Consent records

That is the reason which makes the commercial SMS from only verified businesses and also each and every message is in compliance with the TRAI messaging regulations.

DLT registration is a must for:

• Transactional SMS
• OTP SMS service
• Promotional SMS
• Service alerts & updates

Why TRAI Has Made DLT Registration a Must for Bulk SMS in India

TRAI has introduced DLT as a mandatory process to mainly deal with:

• SMS spam and fraud
• Sender / Template ID misuse
• Unverified promotional messaging

According to the present DLT compliance guidelines, the operators block the SMS traffic that doesn’t have approved headers and templates.

Without DLT:

• Messages fail delivery
• Headers get rejected
• Businesses face compliance risk

Who are the beneficiaries of DLT registration?

First and foremost DLT registration is required for:

• Companies that send transactional bulk SMS
• Brands that consistently engage their customers through promotional SMS campaigns
• New ventures or Startups that send OTP SMS
• Telemarketers and SMS aggregators
• Businesses that use enterprise bulk SMS solutions

Any company that opts for a bulk SMS service must necessarily go through DLT
