Find your Office product key

If you didn’t receive a product key with your new PC, and you see options Try, Buy, or Activate when you start Office, this likely means that your new PC shipped with an Office 365 Home trial that’s good for one month. If you paid for a product key card but didn't receive one, or if your PC was supposed to include a free offer for Office but didn't, please contact your PC manufacturer or the store where you bought your PC.

If you need help activating Office on your new PC or device, see Try, buy, or activate Office that's pre-installed on a new computer and Troubleshoot Office that's pre-installed on a new PC.

For security reasons, the full product key isn't displayed within Office. Instead, you can do one of the following:

• View the Microsoft account that's associated with your Office install by opening Word 2016, PowerPoint 2016, or Excel 2016 and going to File > Account. Look for the email address after Belongs to below the product name. You can use this account to reinstall Office from My Office Account without a product key. If you can't remember the password to your Microsoft account, see I can't remember the Microsoft account I use with Office.

• View the last 5 characters of the product key by using the command-line method described in Manage multiple one-time-purchase Office installs that use the same Microsoft account.

• View the full product key on the My Office Account page.

Viewing your product key on My Office Account works only for the 2013 and 2016 versions of the following products:

• Office Home & Student

• Office Home & Business

• Office Professional

Here's how to view your product key on the My Office Account page:

1. Go to My Office Account, and then select Install from a disc.

   

2. Select I have a disc, and then select View your product key.

   

Do you manage several installations of Office that are all tied to one Microsoft account? Did you lose track of which product key was used to install Office on which PC? If you answered yes to these questions, see Manage multiple one-time-purchase Office installs that use the same Microsoft account to learn how to identify which Office product key was used to install Office on each PC.

If you have already installed multiple one-time purchases of Office and activation is failing on subsequent installs, see Change your Office product key.

If you purchased and downloaded Office from an online store, the product key might be in your email receipt.

Try the following to find this confirmation email:

• Check your spam, bulk, or junk mail folders for the email.

• Try searching your email for the word “Microsoft” or the name of the company where you bought Office.

• If you have multiple email accounts, check the email account that you provided when you purchased Office.

Note: Product keys aren't emailed for online purchases of Office 365 because you don't need a product key when buying Office 365 online.

If the product key isn't in the email receipt or if you can’t find the email receipt, you may be able to retrieve the product key by using the Order History link for the store you made the purchase from:

• Microsoft Store: Go to www.microsoftstore.com and sign in with the user ID and password you used to purchase and download Office. After you sign in, click Digital content to view the product keys.
