Azure Active Directory B2C: Region availability & data residency

Region availability and data residency are two very different concepts that apply differently to Azure AD B2C from the rest of Azure. This article will explain the differences between these two concepts and compare how they apply to Azure versus Azure AD B2C.

Summary

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

Concepts

  • Region availability refers to where a service is available for use.
  • Data residency refers to where user data is stored.

Region availability

Azure AD B2C is available worldwide via the Azure public cloud.

This differs from the model most other Azure services follow which couple availability with data residency. You can see examples of this in both Azure's Products Available By Region page and the Active Directory B2C pricing calculator.

Data residency

Azure AD B2C stores user data in either United States or Europe.

Data residency is determined based on which country/region is selected when creating an Azure AD B2C tenant.

Preview tenant

If you had created a B2C tenant during Azure AD B2C's preview period, it is likely that your Tenant type says Preview tenant. If this is the case, you MUST use your tenant only for development and testing purposes, and NOT for production apps.

Important

There is no migration path from a preview B2C tenant to a production-scale B2C tenant. Note that there are known issues when you delete a preview B2C tenant and re-create a production-scale B2C tenant with the same domain name. You have to create a production-scale B2C tenant with a different domain name.
