# Add an Azure AD tenant and Azure AD subscription
Here's a step-by-step guide to adding an Azure Active Directory tenant, adding an Azure AD subscription, and registering your subscription.

For step-by-step guide to register this free subscription, see [Register your free Azure Active Directory subscription.](#register-your-free-azure-active-directory-subscription)

2. Enter the information for your organization. Click **check availability** to verify that domain name that you selected is available.
3. Complete the login and country information. You must provide a valid phone number, then click **Send text message** or **Call me**.
4. Enter the code that you receive and then click **Verify code**. After the code is verified and the continue button turns green, click **continue**.
5. After you finish creating your Azure account, you are ready to add an Azure AD subscription.
If you don't have a paid subscription to any Microsoft service, you can purchase an Azure AD premium subscription. Go to Office 356 portal, and then sign in using the admin account that you just created in Step 4 (for example, user1@contosoltd.onmicrosoftcom).
6. Click **Install software**.
7. In the Office 365 portal, select **Purchase Services** from the left nagivation.
