Mandatory for every business sending SMS in India. Nesark's experts handle your complete DLT registration, entity approval, Sender ID, and templates in 24–48 hours.
DLT (Distributed Ledger Technology) registration is a mandatory requirement set by TRAI (Telecom Regulatory Authority of India) for any organization that wants to send SMS messages in India. The technology is designed to reduce spam, increase telecom subscriber safety, and improve trust.
A Business Entity must register itself on the DLT portal, register Sender IDs, submit message templates, and get their approval before sending Bulk SMS.
Bulk SMS will NOT be delivered. OTP messages will fail. Your business cannot legally send any SMS in India. Register once — data is synced across all telecom operators automatically.
