Think of a library with thousands of books: you use a library card to track what you’ve borrowed and what you still owe. In Microsoft Azure, subscriptions play a similar role — they are the primary billing, management, and access boundary for cloud resources. This article explains Azure subscription fundamentals, common offer types, and how to view and manage subscriptions in the Azure portal.

​
What is an Azure subscription?

  • An Azure subscription is a logical container that establishes the billing boundary for resource usage and a scope for access control and policy enforcement.
  • Resources you deploy are associated with a subscription — a dedicated logical space where resources are organized and accessed.
  • Subscriptions help create environment boundaries (for example: development, testing, production), allowing tailored security and governance configurations.
  • Each subscription has a unique subscription ID used for management, billing, and auditing.
  • One account can have multiple subscriptions to separate billing and administrative responsibilities across projects or departments.
  • Subscriptions are linked to identities — you need a Microsoft Entra ID (Azure AD) account or a Microsoft account trusted by Microsoft Cloud to sign up for or manage subscriptions.
  • Beyond billing, a subscription is the scope where role assignments and Azure Policy apply.

Role assignments and Azure Policy can be applied at the subscription scope. These assignments and policies are inherited by all resources within the subscription unless overridden at a narrower scope (resource group or resource).

Subscription offer types

Azure provides multiple subscription offers to meet different needs — from enterprise contracts to individual developer plans. Below is a concise overview of the most common offer types and their typical use cases. For full details and current offers, see the Azure offer details page: https://azure.microsoft.com/en-us/offers/.

A mouse cursor is visible hovering over one of the offer links.

Viewing and managing subscriptions in the Azure portal

You can view and manage all subscriptions tied to your account from the Azure portal:
  1. Open the portal (https://portal.azure.com) and search for Subscriptions.
  2. The Subscriptions blade lists entries associated with your account, showing details such as:
    • Subscription ID
    • Directory (tenant)
    • Offer / Offer ID
    • Status (Enabled, Disabled, etc.)
  3. Click a subscription entry to view and manage settings like access control (IAM), policies, resource providers, and billing properties.
  4. From this blade you can also add a new subscription; Azure will validate your eligibility and display available offers.
Common fields you’ll see in the portal:

If you initiate adding a subscription from the portal, Azure will show only the offers for which you are eligible. For example, if you already used a Free Trial on that account, the Free Trial offer will usually not be presented again.
Free Trial eligibility is limited. If you’ve already used a Free Trial on your account, you typically cannot activate another free trial on the same account.
When selecting an offer for a new subscription, some offers may require additional verification (for example, university credentials for Azure for Students) or acceptance of offer-specific terms.

Summary

Azure subscriptions are the foundational billing, governance, and access boundary for cloud resources. Choosing the right subscription offer and organizing subscriptions to reflect your organizational structure (teams, environments, billing units) simplifies cost management, security, and policy enforcement.
