- 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.
- Mixing scripts in one ID: Latin or Arabic letters are accepted, but pick one script per sender ID.
- Spaces or symbols such as _ & ! ( ): many operators strip or refuse them; use a hyphen or nothing.
- One sender ID shared across several companies or use cases: the rule is one sender ID per legal entity per use case.
