OTP SMS in Ghana — How It Works

- Code expires in 5–10 minutes (configurable)
- Webhook confirms delivery and validation
- Supports SMS and WhatsApp channels
- Routes directly to MTN Ghana, Vodafone Ghana, AirtelTigo Ghana
Sender ID for OTP in Ghana
OTP messages in Ghana should use a short alphanumeric sender ID (e.g. "MyApp") for maximum trust. Sender IDs in Ghana must be registered with the National Communications Authority (NCA) via a licensed aggregator. Alphanumeric sender IDs are supported on all major networks.
