How to Track Microsoft Office Product Keys and Order Numbers
Question details
The user needs a reliable method to track and identify which Microsoft Office 2019 product key is installed on each specific computer.

- Product
- Microsoft Office 2019
- Device & OS
- not provided
- Scenario
- Upgrading from Office 2013 to Office 2019 on multiple laptops using a mix of physical and digital license copies.
- Observed behavior
- Product keys appear to change after installation, and information under Payment and Billing does not match the Services and Subscriptions page, making it difficult to match licenses to specific devices.
Ensure you have access to the Microsoft account used to purchase or redeem your Office 2019 licenses, and gather any physical product key cards or digital purchase receipts.
Manage Office Installations via Services & Subscriptions
Redeem and link all your product keys to a single Microsoft account to centralize your license management and view active installations.
When you redeem a retail product key, Microsoft generates a different underlying installation key for your device. This is why the key on your physical card or digital receipt may not match what is actually installed on the computer. Linking them to your Microsoft account is the best way to keep track.
Go to setup.office.com, sign in with your Microsoft account, and enter your 25-character product key to associate it with your account.
Navigate to account.microsoft.com/services and log in. This page will display all Office products associated with your account.
Locate the specific Office 2019 license in the list. Click on 'Install' or 'View product key' to see the specific installation key generated for that license.

Check Installed Product Key via Command Prompt
Find the last 5 characters of the installed Office key on a specific computer to match it against your Microsoft account records.

Frequently Asked Questions
Why does the product key on my computer differ from my purchase receipt?
Microsoft converts the 25-character redemption key from your physical card or receipt into a unique installation key for security purposes. You can find the actual installation key linked to your device in your Microsoft account under the Services and Subscriptions page.
Can I transfer an Office 2019 license to a different computer?
Yes, retail versions of Office 2019 can usually be transferred to another computer you own. You must first completely uninstall the software from the original computer, then install it on the new device from your Microsoft account. You may be prompted to activate by phone to verify the transfer.
Where do I find my Microsoft Office order number?
Your order number can be found in the email confirmation you received at the time of purchase. Alternatively, log into your Microsoft account, navigate to the 'Payment and billing' section, and select 'Order history' to view your previous transactions and their corresponding order numbers.
