Complete steps for DLT registration. Entities not registered on the DLT platform cannot send messages. Follow this 4-step verified workflow.
Includes KYC documents like GST, PAN, TAN, CIN, etc. The process is designed for quick completion. Upon verification, your organization receives a unique Entity ID (PE ID).
SMS headers are classified into 4 categories: Transactional, Promotional, Service Implicit, and Service Explicit. Entities register headers matching their business name. Each header receives a unique Header ID.
Once a content template is created and approved, the entity retains ownership across all telecom platforms. Each template receives a unique Template ID shared across other DLT platforms. Learn more in our Complete Guide to DLT Template Registration ↗.
Once your template is approved on the DLT platform, add all approved templates into the SMSHUB Portal or email them in the Excel format to support@smsindiahub.in for instant binding.
Every Content Template registered by a Principal Entity must contain the ‘Brand Name(s)’ (complete business name, brand name, or trademark) in the message content field. All templates registered must strictly include the registered brand identifier.
For Enterprise registration, telecom operators charge a standard registration/renewal fee of Rs. 5,900/- (inclusive of GST). Upon successful payment and verification (typically 72 working hours), you receive a unique Entity ID valid across all telecom networks.
You can register with any of the authorized telecom operators below as a Principal Entity to get your headers and content templates approved. Once approved on one operator, your Entity ID syncs across all operators.
