# Switch region

Our Sandbox supports multi-region switching, and you can choose the corresponding region according to your actual situation. Currently supported region list:

| Region | Chinese description | Domain name |
| ------- | ---------------- | ---------------------------- |
| cn-wlcb | North China (Ulanqab) | cn-wlcb.sandbox.ucloudai.com |
| us-ca | United States (Los Angeles) | us-ca.sandbox.ucloudai.com |

By default we will use the `cn-wlcb` region. Here's how to switch to another region.

> ⚠️Note: Sandbox and template data in different regions are independent and not interoperable. Your custom template needs to be built separately in different regions.

## SDK Switch region

You can directly switch regions through the `UCLOUD_SANDBOX_REGION` environment variable. (Switching regions requires that the SDK version is greater than or equal to `1.4.0`)

```bash
export UCLOUD_SANDBOX_REGION=xxx
```

For example, if you wish to deploy the sandbox in North America, set this environment variable to `us-ca`.

## CLI switch region

Directly execute the following command to switch regions with one click. (Switching regions requires the CLI version to be greater than or equal to `1.0.3`)

```bash
ucloud-sandbox-cli region
```

The command line will prompt you to select a region. Once selected, it will take effect globally.
