How To Get Azure Tenant ID

Tenant ID

In many cases you need to know the tenant ID of your Azure AD tenant. It’s easy to obtain this information using PowerShell or the Azure Portal.

If you like easy then have a look at our tip at the end of this article!

Get Azure Tenant ID With PowerShell

To retrieve your tenant id using PowerShell you simply need to connect to your Azure AD using the Connect-AzureAD commandlet. This commandlet is part of the AzureAD module, so if you don’t have this module installed already, you need to grab it from the PowerShell Gallery:

  1. Install-Module AzureAD

When the module is installed you can run the Connect-AzureAD command, which will prompt you for your username, password and any multifactor authentication you have set up:

  1. Connect-AzureAD

The tenant ID is readily available in the output from this command:

PS C:\> Connect-AzureAD
Account                              Environment TenantId                             TenantDomain                  AccountType
-------                              ----------- --------                             ------------                  ----------- AzureCloud c1493961-2ba6-41ae-b462-e3e7e4dae630 User

If you want to dive more into the tenant information, use the Get-AzureADTenantDetail commandlet:

  1. Get-AzureADTenantDetail

This command returns a JSON document and the easiest way to handle this output is by inserting it into a variable.

An example of this is shown in the below output:

PS C:\> $tenant  = Get-AzureADTenantDetail
PS C:\> $tenant | ft DisplayName,CountryLetterCode,City,Postalcode,TelephoneNumber
DisplayName               CountryLetterCode City       PostalCode TelephoneNumber
-----------               ----------------- ----       ---------- ---------------

Edit: As noted by Matthew Prentice, enterprise specialist with All Covered, to grab the tenant ID programmatically, use the objectId property of the output from the Get-AzureADTenantDetail command:

PS C:\> (Get-AzureADTenantDetail).objectId

To retrieve the tenant ID from the Azure Portal start by logging in.

Then search for and open the Azure AD Service:

Get Tenant ID

In the Azure AD the tenant ID is visible in the tenant information box:

Get Tenant ID


As seen in the above steps it’s very easy to pick up the tenant ID of your Azure AD. This is a useful parameter when dealing with multiple tenants, doing cross-tenant mail migrations and other advanced tasks.
