# Countries and regional restrictions

Country support does not mean that every provider, method, asset, or operation is available in that country. Some countries require a state, province, or territory selection, and provider restrictions can change independently.

Use the regions endpoint to retrieve countries and nested regions:

```http
GET /api/white-label/v1/regions/
```

If a region has `child_exists: true`, present its `states` and submit the applicable nested region ID. This covers cases such as US states and Canadian provinces without maintaining a second hardcoded list.
