Transactional & Service SMS for Indian Businesses
Transactional SMS is commonly understood as OTP and system alert messaging. Under TRAI DLT regulations, these messages are classified into Transactional SMS and Service SMS, depending on the type of organization. SSD Web Solutions helps businesses send DLT-compliant transactional and service SMS, while we take care of correct classification, routing, and setup — without confusing terminology or compliance risk.
Transactional SMS vs Service SMS
| Transactional SMS | Service SMS |
| Used mainly by banks, financial institutions, and regulated entities | Used by all other businesses |
| Includes OTPs, banking alerts, and financial notifications | Includes OTPs, login alerts, confirmations, reminders, and system notifications |
| Requires stricter DLT entity and template approvals | Operationally behaves the same as transactional SMS for most SMB use cases |
Most businesses refer to both categories as “Transactional SMS”, and we handle the compliance distinction internally.
Common Use Cases
Transactional & Service SMS is typically used for:
- Login and authentication OTPs
- Payment and billing alerts
- Account activity notifications
- Order, booking, and service confirmations
- Appointment reminders and system alerts
These messages are non-promotional, time-sensitive, and critical for customer trust.
