**Short answer:** In Malaysia, sender ID requirements are set by the mobile operators (CelcomDigi (ex-Celcom) and Maxis), with MCMC as regulator. Approval typically takes 5–7 business days. Alphanumeric IDs of up to 11 characters are accepted. OmniChannels.ai handles the filing across 4 operators and confirms current rules during onboarding.

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

1. **Choose and check your sender ID:** Pick a sender ID that matches your brand: Latin or local-script 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 Malaysia: BroadNet confirms the current requirements during onboarding.
4. **Approval and test messages:** Approval typically takes 5–7 business days. Once approved we send test messages on CelcomDigi (ex-Celcom), Maxis, CelcomDigi (ex-Digi) and U 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 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.
