Azure Active Directory B2C: Region availability & data residency

Azure Active Directory B2C (Azure AD B2C) stores customer data in a geographic location based on how a tenant was created and provisioned. For the Azure portal or Microsoft Entra API, the location is defined when a customer selects a location from the pre-defined list.

Region availability and data residency are two different concepts that apply to Azure AD B2C. This article explains the differences between these two concepts, and compares how they apply to Azure versus Azure AD B2C. Region availability refers to where a service is available for use whereas Data residency refers to where user data is stored.

Azure AD B2C is generally available worldwide with the option for data residency in the United States, Europe, Asia Pacific, or Australia.

Region availability refers to where a service is available for use. Data residency refers to where customer data is stored. For customers in the EU and EFTA, see EU Data Boundary.

If you enable Go-Local add-on, you can store your data exclusively in a specific country/region.

Region availability

Azure AD B2C service is available worldwide via the Azure public cloud. You can see availability of this service in both Azure's Products Available By Region page and the Active Directory B2C pricing calculator. Also, Azure AD B2C service is highly available. Learn more about Service Level Agreement (SLA) for Azure Active Directory B2C.

Data residency

Azure AD B2C stores customer data in the United States, Europe, the Asia Pacific region, Japan or Australia.

Data residency is determined by the location you select when you create an Azure AD B2C tenant:

To find the exact location where your data is located per country/region, refer to where Microsoft Entra data is locatedservice.

Go-Local add-on

Go-Local refers to Microsoft’s commitment to allow some customers to configure some services to store their data at rest in the Geo of the customer’s choice, typically a country/region. Go-Local is as way of fulfilling corporate policies and compliance requirements. You choose the country/region where you want to store your data when you create your Azure AD B2C.

The Go-Local add-on is a paid add-on, but it's optional. If you choose to use it, you'll incur an extra charge in addition to your Azure AD B2C Premium P1 or P2 licenses. See more information in Billing model.

At the moment, the following countries/regions have the local data residence option:

  • Japan

  • Australia

Remote profile solution

With Azure AD B2C custom policies, you can integrate with RESTful API services, which allow you to store and read user profiles from a remote database (such as a marketing database, CRM system, or any line-of-business application).

  • During the sign-up and profile editing flows, Azure AD B2C calls a custom REST API to persist the user profile to the remote data source. The user's credentials are stored in Azure AD B2C directory.
  • Upon sign in, after credentials validation with a local or social account, Azure AD B2C invokes the REST API, which sends the user's unique identifier as a user primary key (email address or user objectId). The REST API reads the data from the remote database and returns the user profile.

After sign-up, profile editing, or sign-in action is complete, Azure AD B2C includes the user profile in the access token that is returned to the application. For more information, see the Azure AD B2C Remote profile sample solution in GitHub.
