BTRC Guidelines for Educational SMS Gateways in Bangladesh: Masking vs. Non-Masking

## Ensuring 99.8% SMS Delivery for Guardians Sending an SMS to a guardian when their child is absent or when monthly model test marks are published is the strongest trust-builder an academic institution has. However, many institutions face blocked SMS alerts or heavy delivery delays due to unregistered sender IDs and non-compliance with Bangladesh Telecommunication Regulatory Commission (BTRC) regulations. ### Key Rules to Follow 1. **Official Sender Masking**: Educational institutions can register their custom 11-character alphanumeric name (e.g. `EXCELLENCE`, `ACADEMY`). 2. **DND Handling**: Transactional academic alerts (such as fee receipts and absent notifications) are whitelisted through high-priority telco routes. 3. **Template Pre-Approval**: Standardized dynamic templates ensure fast delivery during evening peak hours (7:00 PM – 9:30 PM).
