Question details

A Microsoft 365 user wants to know how to locate their User Principal Name (UPN) when they do not have administrative access to the Microsoft 365 admin center.

How to Find Your Microsoft 365 UPN (User Principal Name)

Product: Microsoft 365
Device & OS: not provided
Scenario: Trying to find account login details (UPN) for configuration or authentication purposes without having administrative rights to the tenant.
Observed behavior: The standard Microsoft 365 user portal does not visibly expose the User Principal Name to standard users.

Before you start

Note that standard user accounts in Microsoft 365 often have restricted views of their deeper technical account details, such as the UPN. You will likely need to communicate with your organization's IT department to retrieve this exact information.

Solution 1Recommended

Contact Your Organization's IT Administrator

Since Microsoft 365 does not natively display the UPN to non-admin users, reaching out to your IT department is the most direct and reliable method.

IT administrators have access to the Microsoft 365 Admin Center and Microsoft Entra ID, where every user's UPN is explicitly listed.

Identify IT Contact

Locate your company's IT support email, help desk portal, or ticketing system.

Submit a Request

Create a new support ticket or draft an email asking for your exact User Principal Name (UPN).

Provide Verification

Include your standard work email address or employee ID to help the administrator quickly locate your Microsoft Entra ID account.

Contact Your Organization's IT Administrator

Fastest Resolution: Your IT Admin can copy and paste the exact UPN from their portal, ensuring you don't use an incorrect alias.

Solution 2

Check Your Primary Work Email Address (Workaround)

In many modern organizations, a user's UPN is configured to be completely identical to their primary Microsoft 365 email address.

Solution 3

Submit a Feature Request to Microsoft

If you believe users should be able to view their own UPN directly from their account profile, you can submit a feature request to the developers.

Frequently Asked Questions

What exactly is a UPN in Microsoft 365?

A User Principal Name (UPN) is the name of a system user in an email address format (e.g., username@domain.com). It acts as the primary login ID for authenticating into Windows devices, Microsoft Entra ID, and cloud services like Microsoft 365.

Is my UPN always the same as my primary email address?

Not always. While it is a best practice and very common for the UPN and primary email address to match, administrators can assign a UPN that differs from your public email alias, especially in organizations with multiple domain names.

Can I view my UPN in Microsoft Entra ID (Azure AD)?

Standard users typically do not have read access to directory properties in Microsoft Entra ID. Unless an administrator has explicitly granted permissions or allowed access to the user profile portal, you will be blocked from viewing the raw directory data where the UPN is stored.
