# Log in to commercetools Regions **Introducing Identity**: We've launched an authentication service that provides access to our business tools and other offerings using a single commercetools account. To learn more about this change, including what you need to do, see our [Identity](/docs/identity/overview.md) documentation. commercetools commerce APIs are provided in multiple cloud infrastructures and locations, called **Regions**. For more information about how to get started, see our [self-service sign-up](/api/getting-started/initial-setup.md). User accounts are separate per Region. Authentication will fail when logging into a different Region than the one the account was created in. The same email address can have independent user accounts in multiple regions. | Region | Link | | --- | --- | | North America (Google Cloud) | Merchant Center | | North America (AWS) | Merchant Center | | Europe (Google Cloud) | Merchant Center | | Europe (AWS) | Merchant Center | | Australia (Google Cloud) | Merchant Center |
