## How to register your sender ID in New Zealand 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 set up the sender with the operators:** We set the sender up with each operator. Current process in New Zealand: No published sender-ID registry; operator requirements confirmed during onboarding.
4. **Approval and test messages:** There is no pre-registration step. Before launch we send test messages on Spark NZ, One NZ (Vodafone NZ) and 2degrees 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 New Zealand

- 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.
- Expecting the alphanumeric ID on every network: some networks replace it with a numeric sender.
