+## Frequently asked questions about Azure subscriptions
+
+The following are answers to some common questions about connecting an Azure subscription to your account on {% data variables.product.prodname_dotcom %}.
+
+### Can I connect more than one enterprise or cost center to the same Azure subscription?
+
+Yes. There’s no limit to the number of enterprises or cost centers you can connect to a single Azure subscription. For details on how charges are applied to cost centers, see [AUTOTITLE](/billing/using-the-new-billing-platform/charging-business-units).
+
+### Can I connect multiple Azure subscriptions to one enterprise?
+
+Yes. You can connect multiple Azure subscriptions to a single enterprise account by creating **cost centers**. Cost centers let you allocate metered usage across different Azure subscriptions.
+
+### How are charges split in Azure for multiple enterprises?
+
+Azure usage is separated by **SKU** and either **enterprise ID** or **cost center ID**. The format used is `enterprise:sku` or `costcenter:sku`.
+
+> [!NOTE]
+> Azure currently shows internal IDs, which may make it difficult to identify the corresponding enterprise or cost center.
+
+### What happens if I don’t assign an Azure subscription to a cost center?
+
+Charges will fall back to the **enterprise-level Azure subscription**. This also happens if a cost center becomes invalid or is deleted—any future usage from those resources is billed to the enterprise-level subscription.
+
+### Can billing managers connect to Azure subscriptions?
+
+Yes. Billing managers for organizations or enterprises can connect Azure subscriptions.
+
+### Can I use metered products during an {% data variables.product.prodname_emu %} trial without connecting an Azure subscription?
+
+Yes. During an **{% data variables.product.prodname_emu %} trial**, you can use metered products up to the included limits. To exceed the included limits, you’ll need to link an Azure subscription.
