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.
