## Sending SMS to Belgium

- Country code: BE (dialing +32)
- Channels available: sms, whatsapp, voice
- Two-way messaging: yes

### Sender types

| Sender | Direction | Throughput (msg/s) | Registration | Timeline |
| --- | --- | --- | --- | --- |
| Alphanumeric Sender ID | one-way | — | required (alpha) | — |
| Long code (phone number) | two-way | — | not required | — |

### Rules

- Consent model: opt-in
- Template pre-approval: no
- Quiet hours: enforced

- Custom alphanumeric Sender IDs will be converted to short codes by local operators due to Belgian regulations.
- Custom numeric Sender IDs are only available if the number is procured from Bird.
- Belgium enforces strict segmentation between marketing and transactional messaging:
  - Each Sender ID can only be registered for one segment—either marketing or transactional. If your content spans both, you must register separate Sender IDs for each.
  - **Marketing segment:** Messages will not be delivered to DND (Do Not Disturb) numbers—those who have opted out of promotional content.
  - **Transactional segment:** Messages are delivered to all recipients, including DND numbers.

#### What this market refuses
