DLT Free OTP API for India
TRAI's DLT registration takes weeks of paperwork and approvals. StartMessaging lets you skip all of that and start sending OTPs in minutes. We handle the DLT compliance — you focus on your product.
What is DLT and Why is it a Problem?
TRAI's Distributed Ledger Technology (DLT) framework requires every business to register before sending SMS in India. Here's what that involves:
Register your business entity with the DLT platform. Requires company documents, GST certificate, and PAN card.
Submit every message template for approval. Each template takes 1-7 days to get approved. Changes need re-approval.
Register sender IDs (headers) with the DLT platform. Each header needs separate approval from your telco.
The entire DLT registration process takes 2-4 weeks minimum. Any mistakes mean starting over.
How StartMessaging Makes DLT Irrelevant
StartMessaging is a fully DLT-registered OTP provider. We have already completed entity registration, sender ID setup, and template approvals on the DLT platform.
When you send an OTP through our API, the message is routed through our pre-approved DLT channels. Telecom operators see a valid, registered message — so your OTPs get delivered just like any other DLT-compliant SMS.
This means you get full DLT compliance without any of the registration burden. No entity forms, no document uploads, no template approvals, no waiting.
