What is DLT registration?
DLT stands for Distributed Ledger Technology — a blockchain-based system that records transactions between everyone in the network.
Businesses that want to send SMS register as principal entities on a DLT platform and get a 6-character sender ID. Messages then go out under that sender ID instead of a name or phone number.
TRAI requires every company sending SMS to Indian customers to register on an operator’s DLT platform. It was introduced in the public interest to stop unsolicited bulk SMS — companies that don’t register can’t send bulk SMS in India.
Why DLT is required
It looks like a headache at first — but it protects honest businesses and their customers.
Protects customers from Unsolicited Commercial Communication (UCC) and random spam messages and calls.
Every business, header and template is registered, so the industry stays transparent and secure.
Only registered principal entities with registered sender IDs can send SMS to Indian customers.
Register on any one portal — your registration works across all operators.

Questions, answered
What is DLT registration?
DLT (Distributed Ledger Technology) is a blockchain-based registration system mandated by TRAI. Businesses register as principal entities, then register their 6-character sender ID (header) and message templates before they can send SMS in India.
Is DLT registration mandatory?
Yes. Every business that sends commercial SMS to Indian customers must register on a DLT platform. Unregistered businesses cannot send bulk SMS.
What documents do I need?
Your PAN and a business proof — GST certificate, Udyam registration or certificate of incorporation.
How long does registration take?
With our guidance, entity registration is usually approved in about 2 days. Header and template approvals follow after that.
Do I have to register on every operator?
No. Registering on any one operator’s DLT portal is enough — your registration is shared across operators.
