What is DLT Registration?

DLT (Distributed Ledger Technology) is a blockchain-based registration system mandated by TRAI. It requires all businesses to register their entity, headers, and templates to send commercial SMS. StartMessaging completely bypasses this manual setup by mapping your messages to pre-registered compliant routes automatically.

  • TRAI regulations compliant
  • Prevents SMS header spoofing and spam
  • Entity, header, and template checks

DLT SMS — Frequently Asked Questions

Is DLT registration mandatory in India?

Yes. TRAI mandates DLT registration for all commercial SMS in India. However, with StartMessaging, you use our pre-registered routes for transactional messages, so you don't need to register yourself. For promotional messages, individual DLT registration is required.

How long does DLT registration take?

Traditional DLT registration takes 2-4 weeks including entity registration, header approval, and template approval across DLT platforms. With StartMessaging's pre-registered routes, you can start sending transactional SMS in under 5 minutes.

What's the difference between DLT-registered and non-DLT SMS?

DLT-registered SMS are sent through officially registered headers and templates on India's DLT blockchain. Non-DLT approaches use pre-registered routes operated by authorized entities (like StartMessaging). Both are TRAI-compliant, but using pre-registered routes is faster and simpler for transactional messages.
