### Sender types

| Sender | Direction | Throughput (msg/s) | Registration | Sender ID | Timeline |
| --- | --- | --- | --- | --- | --- |
| Alphanumeric Sender ID | one-way | — | required (alpha) | overwritten after approval (random short code) | — |
| Long code (phone number) | two-way | — | required (numeric) | preserved | — |

### Rules

- Consent model: opt-in
- Template pre-approval: no
- Quiet hours: recorded; the sending window is not stated

- 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

Gambling, adult & betting content is not allowed.

## How sending works

Use the same SMS API across supported destinations. Prepare an eligible sender, enable the destination and apply the recipient permission your message requires. Track the accepted message through carrier submission and the delivery reports available for that route.
