Common reasons a sender ID is rejected in Malaysia
- 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 local-script 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.
