# EU Region

> Learn about Zuddl's EU region and how to access it

Zuddl is available in a dedicated EU region. Accounts hosted in the EU region get the same product, features, and setup as the US region — nothing works differently. The only difference is the URLs you use to access Zuddl.

***

## How to know your region

Your sign-in domain tells you which region your account is hosted in. If the domain you use to sign in to the Zuddl dashboard contains `eu`, your account is in the EU region. Otherwise, it is in the US region.

***

## EU region URLs

Use the URLs for the region your Zuddl account is hosted in.

| Surface             | US region (default)       | EU region                    |
| ------------------- | ------------------------- | ---------------------------- |
| Organizer dashboard | `https://setup.zuddl.com` | `https://setup.eu.zuddl.com` |
| Attendee app        | `https://app.zuddl.com`   | `https://app.eu.zuddl.com`   |
| API base URL        | `https://api.zuddl.com/`  | `https://api.eu.zuddl.com/`  |

<Note>
  API keys are region-scoped — a key issued in one region is not valid in the other. See the [API Reference introduction](/api-reference/introduction) for details on base URLs, API keys, and rate limits.
</Note>

## Same setup, everywhere

Everything in these docs applies identically to EU-region accounts. Follow any guide as written — just substitute the EU URLs above wherever a US URL appears.
