What is DLT (Distributed Ledger Technology for SMS)?

In the context of Indian telecommunications, DLT (Distributed Ledger Technology) refers to the TRAI-mandated blockchain-based platform where businesses must register their entity, sender IDs, and SMS templates before sending commercial messages.

DLT registration involves four phases: entity registration (business details and documents), header registration (sender IDs like IN-BRAND), template registration (exact message content with variables), and consent registration (opt-in proof). Non-compliance results in message blocking by telecom operators.

InboxCentral's SMS API handles DLT-compliant message routing and provides guides for completing the registration process.
