Linking an Azure Subscription to an Azure AD B2C tenant
The latest information on usage billing and pricing for Azure AD B2C is at the following page: Azure AD B2C Pricing
Usage charges for Azure AD B2C are billed to an Azure subscription. When an Azure AD B2C tenant is created, the tenant administrator needs to explicitly link the Azure AD B2C tenant to an Azure subscription. This article shows you how.
A subscription linked to an Azure AD B2C tenant can only be used for the billing of Azure AD B2C usage. The subscription cannot be used to add other Azure services or Office 365 licenses within the Azure AD B2C tenant.
The subscription link is achieved by creating an Azure AD B2C "resource" within the target Azure subscription. Many Azure AD B2C "resources" can be created within a single Azure subscription, along with other Azure resources (for example, VMs, Data storage, LogicApps). You can see all of the resources within the subscription by going to the Azure AD tenant that the subscription is associated to.
A valid Azure subscription is needed to proceed.
Create an Azure AD B2C tenant
You must first create an Azure AD B2C tenant that you would like to link a subscription to. Skip this step if you have already created an Azure AD B2C tenant.
Open Azure portal in the Azure AD tenant that shows your Azure subscription
Navigate to the Azure AD tenant that shows your Azure subscription. Open the Azure portal, and switch to the Azure AD tenant that shows the Azure subscription you would like to use.
Find Azure AD B2C in the Azure Marketplace
Click the New button. In the Search the marketplace field, enter
In the results list, select Azure AD B2C.
Details about Azure AD B2C are shown. To begin configuring your new Azure Active Directory B2C tenant, click the Create button.
In the resource creation screen, select Link an existing Azure AD B2C Tenant to my Azure subscription.
Create an Azure AD B2C resource within the Azure subscription
In the resource creation dialog, select an Azure AD B2C tenent from the dropdown. You will see all of the tenants that you are the global administrator of and those that are not already linked to a subscription.
The Azure AD B2C resource name will be preselected to match the domain name of the Azure AD B2C tenant.
For Subscription, select an active Azure subscription that you are the administrator of.
Select a Resource Group and Resource Group location. The selection here has no impact on your Azure AD B2C tenant location, performance, or billing status.
Manage your Azure AD B2C tenent resources
Once an Azure AD B2C resource is successfully created within the Azure subscription, you should see a new resource of type "B2C tenent" added alongside your other Azure resources.
You can use this resource to:
- Navigate to the subscription to review billing information.
- Go to your Azure AD B2C tenant
- Submit a support request
- Move your Azure AD B2C tenant resource to another Azure subscription or to another Resource Group.
Currently, an Azure AD B2C tenant cannot link to CSP subscriptions.
A user may have established a regional restriction for Azure resource creation. This restriction may prevent the creation of Azure AD B2C resource. To mitigate, please relax this restriction.
Once these steps are complete for each of your Azure AD B2C tenants, your Azure subscription is billed in accordance with your Azure Direct or Enterprise Agreement details.
You can review the usage and billing details within your selected Azure subscription. You can also review detailed day-by-day usage reports using the usage reporting API.
