THREE QUICK FACTS ABOUT PRODUCT KEYS

  • Most customers won’t receive (and don’t need) a product key to get started with Office. For instance, you don't need a key if you bought Office from Office.com or the Microsoft Store online, or if you got Office for free through your school.

  • If your purchase of Office 2016 or Office 2013 did include a product key, you'll only need to use it once, for activation. If you bought an older version of Office, you should keep your product key in a safe place for future use. See help for Office 2007 or Office 2010.

  • An Office product key uses a combination of 25 letters and numbers, and looks like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. You don’t have to enter the dashes.

If you received a physical box or card, look on the packaging or card for the product key.

If you didn’t receive a physical product, the key should be in your email receipt from the store.

Can’t find it? Try logging into the site where you purchased Office to check your order details. If you still can’t find your product key, contact the seller to ask for the link or receipt to be resent. If you misplaced your key before you redeemed it, you may need to purchase a replacement.

You don’t need a product key to activate Office.

To get started, go to Office 365 Education and sign up with your school email address. If your school provides the full Office desktop apps, you’ll see the Install button on your Office 365 home page after you sign up.

  3. In the window that opens, choose Activate.

  4. Do one of the following:

    • If you're asked to sign in with your Microsoft account, that means you don't need a product key. Just sign in with your Microsoft account to activate the Office software that came with your device.

      Note   The Microsoft account you use to sign in will be associated with your personal copy of Office. If you don't have one yet, you can create a Microsoft account here. It's important that you remember your email address and password so you can access your My Account page, which is where you'll go to reinstall Office and manage any subscriptions you have.

    • If you’re asked to enter a product key, that means a key was included with your purchase. Look for it on your Certificate of Authenticity or on a card in the packaging. If you can’t find it, contact the seller.
