Complete step-by-step procedure for DLT registration. Entities not registered on the DLT platform cannot send messages. Follow this 4-step verified workflow.

Register 6-character alphabetic sender IDs matching your registered business name or brand (e.g., SIHHUB) for transactional and service alerts, or 6-digit numeric headers for promotional campaigns. Each approved header gets a unique Header ID.
Submit SMS message text with designated variable tags ({#var#}) and your registered brand name. Once approved by your registrar telecom operator, your Template ID synchronizes across all other Indian operators. Learn more in our Complete Guide to DLT Template Registration ↗.
Once your templates are approved, add your approved Template IDs into the SMSINDIAHUB web portal or share your template list with our support team at support@smsindiahub.in for instant telemarketer 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 fee of Rs. 5,900/- (inclusive of GST). Upon successful payment and verification (typically 48 to 72 working hours), you receive a unique Entity ID valid across all telecom networks in India.
