# Base URL and regions

> The five regional production hostnames available today and how to determine which region hosts your account.

Givergy operates regional production deployments. **Every customer account is hosted in exactly one region**, and every endpoint documented here is served by that region's hostname. Throughout these docs the placeholder `{EMS_BASE_URL}` stands for the production hostname for your account's region.

## Available regions today

| Region         | Production hostname       | Demo / sandbox hostname        |
| -------------- | ------------------------- | ------------------------------ |
| United Kingdom | `https://uk.givergy.com`  | `https://uk.demo.givergy.com`  |
| United States  | `https://us.givergy.com`  | `https://us.demo.givergy.com`  |
| Canada         | `https://can.givergy.com` | `https://can.demo.givergy.com` |
| Australia      | `https://aus.givergy.com` | `https://aus.demo.givergy.com` |
| Hong Kong      | `https://hk.givergy.com`  | `https://hk.demo.givergy.com`  |

<Warning>
  Note the **`aus`** prefix for Australia and the **`can`** prefix for Canada — both are intentionally three letters, not the two-letter ISO codes.
</Warning>

<Info>
  **Coming Soon — additional regions.** If your data-residency requirements need a region not listed above, contact [support@givergy.com](mailto:support@givergy.com) to discuss timelines.

## Which region am I in?

If you don't know which region hosts your account, the simplest way to find out is to ask Givergy: [support@givergy.com](mailto:support@givergy.com).

Alternatively, the Givergy product UI for your account loads from one of these subdomains. The part before `.givergy.com` (e.g. `us` in `us.givergy.com`) is your region prefix and resolves to the same hostname as the API base URL.

Internally Givergy resolves region from your account locale:

| Account locale | Region            |
| -------------- | ----------------- |
| `en_US`        | `us.givergy.com`  |
| `en_CA`        | `can.givergy.com` |
| `en_AU`        | `aus.givergy.com` |
| `en_HK`        | `hk.givergy.com`  |
| anything else  | `uk.givergy.com`  |

## White-label hostnames

Some customers operate white-label hostnames (for specific charities or events) that share infrastructure with these regions. **Those are not part of the public API surface and should not be hit directly** — always call the regional hostname for your account.

## Cross-region behavior

The five production hostnames are **independent deployments with independent databases**. Cross-region queries are not possible — an integration is always scoped to a single region. If you need data from multiple regions, you'll need separate integrations per region.
