How to Find Your Microsoft Office Product Key

Are you having trouble reinstalling your Microsoft Office? In all likelihood, you’ve forgotten your product activation key. It’s difficult to find, so you might be panicking trying to remember the lost activation code. There are four types of Microsoft Office software: Retail, Subscription, Volume, and OEM. Each one has specific methods for installation and reinstallation, as well as how the product key gets stored and used.

How to Find Your Microsoft Office Product Key

Unfortunately, Microsoft made changes beginning with Office 2013, where only the last five digits of the product key gets stored on your PC.

There is no way to obtain the full Product Key using commands or third-party software unless you use Office 2010 or earlier. Your only option is to keep track of your device installs and the corresponding Office versions. That way, you can match the correct version using your list later once you obtain the last five characters of the current product key on the PC.

The only chance you have to get all twenty-five digits is if you have one of the following:

  • You received an Office volume key from administration in your organization.
  • You bought a PC that came with Office (usually for 1 year only though), and it has a sticker with the product key.
  • You purchased a physical, retail version of Office with the product key in the packaging.
  • You received a purchase email from a third-party seller/distributor that contains your new product key.

Once you register the product key in your Microsoft account, your PC will only contain the last five characters of the key. However, you won’t need it anymore because Microsft attached the install key to your account. All you have to do is log in and choose to download Office—no key required. Your product key becomes your Microsoft account instead.

You CAN have more than one Office version in your Microsft account, as well as more of the same version. If you have two or more of the same, it reports the number of copies to choose from.

Whenever you need to reinstall Office on the same PC or switch it to a different one, you can download the correct or desired Office version from your account and install it without needing a product key. If using a different PC, it will deactivate the previous one, and you may need to use phone activation unless you have a 365 subscription that automatically handles it. For licenses allowing more than one PC, it should automatically activate once opened and attaches it to the same Microsft account it is stored in.

Yes, you can still use product keys to install Office 2013, 2016, 2019, 2021, and 365 if you have one. After that, the key becomes your Microsoft account.

How to Find Your Microsoft Office 2013/2016/2019/2021 Product Key on a Windows PC

Since you cannot obtain the entire product key from your device, or in most cases, from your Microsoft account, you have to do a little scavenger hunting. You CAN get the last five characters of your product key from your PC, then search for the original purchase email, obtain the product packaging, or contact your administrator to receive the key again.

When obtaining the last five characters, and, depending on which version of Windows you’re using, the steps for accessing the partial key are a bit different.

How to Find the Office Product Key on Windows 7 and Earlier Versions

With Windows 7 or an earlier version of the operating system, you don’t need additional software to find the product key.

Purchasing Windows from the Microsoft Store

If you’ve bought the Windows license through the Microsoft Store, the product key copy is saved in your Microsoft Account. This means that Microsoft has sent you the key in a confirmation email. Search through your inbox to find it. If you don’t see it, go through the junk folder.

Here’s what to do if the email is nowhere in sight:

  1. Log into the Microsoft Store and go into Downloads.
  2. Select Product Keys and open the Subscriptions page.
  3. Tap the Digital Content tab to view all your purchases and product keys.

You should see the product key among the items on the list.

Purchasing Windows from a Retailer

A licensed retail store can also sell Windows products. They come in a box with a small business card containing the product key. If you’ve saved the card, flip it over to see the key.

Also, you might have taken a picture of the key as an online backup. If you suspect you saved an image, go through your gallery until you find the picture that matches the last five characters.

Alternatively, when you purchased a PC, the product key can be found on the computer’s chassis sticker or in printed materials. Although the sticker can rub off over time, you can check your device to see if the key is still visible.

How to Find the Product Key on Windows 10 and Windows 11

With software like Windows 10 and 11, you can use command prompts or third-party software to recover the last five characters of your product key. Once you have that, you can search your email accounts for a match and get the entire product key, or you can find the original packaging that includes those last five characters, or contact your administrator in networked situations.

How to Find Product Key Using Windows PowerShell or Command Prompt

If you’re looking for the Microsoft Office product key on Windows 10 or 11, you can use Windows PowerShell or Command Prompt as long the Office version is/was purchased through the Workplace Discount Program (formerly Home Use Program).

  4. You can also use:
    (Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey

Your product key will appear in the window when the command is executed. If not, you have an Office retail version rather than a digitally purchased one.

Here’s how to find the product key using the command prompt on Windows 10/11:

  1. Simultaneously press the Windows + S keys to open Windows search.
  2. Type “cmd” and select Run as administrator from the search results.

Your key will appear onscreen. You can take a picture of it or store it online for safekeeping.

How to Find Your Microsoft Product Key in the Windows Registry File

If you don’t want to use a third-party app to recover the product key, there’s an alternate way to do it. It’s possible to access the key in the Windows Registry File, but you’ll need the correct command.

To pull up the key from the Registry File:

  1. Go to the Search menu and type “regedit” and select it.
  2. Now, find and open the following key:
    Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
  3. The window will generate a list of files. Go to the BackupProductKeyDefault key.

The product key is recorded next to the BackupProductKeyDefault key in the Data column

How to Find Your Product Key with Microsoft Support

When you’re in a hurry or feel like you need a bit of extra guidance, you can try contacting the Microsoft Support team. Here’s how to ask for assistance:

  1. Simultaneously press the Windows + I keys to enter Settings and type “Activation settings” in the search bar.
  2. Tap Get help on the right part of the desktop.
  3. Choose your reason and select Contact Support.
  4. Tap your product type and click Confirm.
  5. Choose Provide your phone number and a support agent will call you.

After you enter your personal information, the support team will reach out to you.

How to Find Your Microsoft Office Product Key on a Mac

First, try using the one-time PIN. To do so:

  1. Locate the packaging or card that came with your Microsoft Office.
  2. When you find the PIN, visit this Microsoft website and type it in.

How to Find Your Microsoft Office Product Key in the Home Use Program

Your Mac could be using the Home Use Program version of Office. In that case, you’ll have to get a product code instead of a product key.

Here’s how to find the code:

  1. Enter the Home Use Program.
  2. Type your country or region and work email address.
  3. Select Don’t Know Your Program Code?
