Implementation checklist
| Area | Why it matters | Recommended practice |
|---|
| Phone number format | Invalid numbers create avoidable failures | Normalize recipients to E.164 format before sending |
| OTP rate limits | High-frequency requests can trigger abuse filtering | Limit attempts by phone number, IP, account and device |
| Message ID storage | Support teams need traceability | Store messageId, recipient, country, template and timestamp |
| Delivery reports | API success does not always mean handset delivery | Track submitted, delivered, failed, expired and rejected statuses |
| Webhook handling | Applications need automated status updates | Use idempotent webhook processing with retry logic |
Signals to monitor
Delivery rate
Measure delivery by country, carrier, template and time window instead of relying only on API request success.
Failure reasons
Group failures by invalid number, carrier rejection, blocked content, expired message and route issue.
Latency
For OTP messages, monitor seconds to delivery because delayed verification can reduce user completion.
User completion
The best SMS workflow is measured by whether users can complete signup, login or transaction confirmation.

Designing a Secure and Reliable OTP SMS Flow
OTP messages should be short, immediately recognizable and valid only for a limited period. The message should identify the service, state that the code must not be shared and avoid unnecessary links.
Security controls should cover both code validation and message sending. Limit attempts by account, phone number, device and IP address, and track delivery latency because delayed codes reduce successful verification.
Implementation checks
- Use a short expiry period appropriate for the transaction risk.
- Do not invalidate a code merely because a delivery receipt is delayed.
- Apply cooldowns before allowing another code to be requested.
- Prevent replay by accepting each successful code only once.
- Monitor resend rate, delivery latency and verification completion.
