DLT Registration (Distributed Ledger Technology Registration) is now mandatory in India for all businesses, enterprises, and telemarketers that want to send promotional SMS, transactional SMS, or service messages. Implemented by TRAI, the DLT platform registration ensures transparency, prevents SMS spam, and helps brands build customer trust. Whether you are registering your entity, SMS header, or template, the process must be completed through an approved DLT operator like Airtel, Jio, BSNL, Vodafone, or MTNL.
By completing your DLT SMS registration, you get a unique Entity ID, Header ID, and Template ID, allowing you to send bulk SMS in compliance with TRAI regulations. From content template registration to PE-TM chain binding, the DLT process in India guarantees verifiable customer consent, secure communication, and seamless delivery across networks using blockchain technology.
