## How to register your sender ID in Namibia through OmniChannels.ai

1. **Choose and check your sender ID:** Pick a sender ID that matches your brand: Latin letters, up to 11 characters. Test it in the free sender ID checker first.
2. **Send us your company details and use case:** Tell us the legal entity, brand and what each sender ID will send (OTP, transactional or promotional). We confirm which supporting documents are currently needed.
3. **We file with the operators:** We prepare and submit the application. Current process in Namibia: BroadNet confirms the current requirements during onboarding.
4. **Approval and test messages:** Approval typically takes 5–10 business days. Once approved we send test messages on MTC Namibia and TN Mobile and check the sender ID displays correctly.
5. **Go live:** Send through the REST API, SMPP or campaigns. Schedule promotional sends for the recipient's local daytime. Opt-out handling is applied to every promotional message.

## Common reasons a sender ID is rejected in Namibia

- Too long: sender IDs here are up to 11 characters.
- Generic words instead of a brand, such as INFO, SMS, OTP, ALERT: regulators usually refuse them.
- Arabic, accented or other non-Latin letters: this market lists Latin letters only.
- Spaces or symbols such as _ & ! ( ): many operators strip or refuse them; use a hyphen or nothing.
