Using product keys with Office 365, Office 2016, or Office 2013
Your Microsoft account takes the place of your Office product key for many tasks, such as activating Office and reinstalling Office. Check the sections below to find out if you need an Office product key and what to do with your key if you have one.
Office is asking me for a product key
If Office is asking you for a product key to activate Office, in many cases you can enter your work, school, or personal Microsoft account instead. This is the account that you used to buy or subscribe to Office. We can help if you forgot your Microsoft account or password.
Note: If you bought a new, unused Office 365 product key card to renew an Office 365 subscription or to buy your trial, you can enter that product key if Office prompts you for it. You can also enter the product key at www.office.com/setup.
There are a few exceptions where you'll need to do something other than sign in.
-
If you bought Office through your employer's Microsoft HUP benefit, you'll need your product key to install Office on a PC. To locate your product key online, see Get your Microsoft HUP product key.
-
If you're using a volume license version of Office Professional Plus at work, you'll need to contact your admin for a product key.
-
If you see a yellow or red banner in an Office app that says SUBSCRIPTION EXPIRED, you must renew your Office 365 subscription to keep using Office. For help, see Renew Office 365 for home.
-
If Office came pre-installed on your new device, and you see a yellow or red banner in an Office app that says PRODUCT NOTICE Most of the features of <app> have been disabled because it hasn't been activated, you must start a new Office 365 Home trial, sign in with a Microsoft account that's associated with Office, or buy Office. For help, see Activate Office 365, Office 2016, or Office 2013.

If you bought Office Professional Plus online, see Can I buy a product key? or, if your product key isn't working, see My Office product key isn't working.
My new Windows 10 PC came with Office but I can't find a product key
If you see a Let's get started screen with options to try, buy, or activate Office, this means that Office is installed on your new PC as a 1-month trial of Office 365 Home. You won't receive a product key from your PC manufacturer unless you paid for an Office product key card. Instead, you can start a trial of Office 365 Home, or buy Office. Here are the two screens you might see:
If you paid for an Office product to be included on your new Windows 10 PC, a digital product key is transmitted to your PC when you activate Windows 10. You won't receive a printed product key. Instead, you'll see a message similar to the following when you start Word 2016 (or any Office app).
For help, see Activate Office 365, Office 2016, or Office 2013.

Can I view my product key in Office?
No, you can't. For security reasons, the full product key isn't displayed within Office.
Instead, for Office 365 and Office 2016, you can view the Microsoft account that Office belongs to. This account takes the place of your product key and can be used to reinstall Office from www.office.com/myaccount and to activate Office.
To view the Microsoft account that Office belongs to, open a document in Word 2016 (or any Office app) and go to File > Account. Look for the email address after Belongs to below the product name.
Can I view my product key online?
If you bought Office 365
Your Office 365 product key isn't displayed online. If Office 365 is prompting you for a product key, you can sign in using the Microsoft account that you used to buy and download Office 365.
If you bought Office Home & Student, Office Home & Business, Office Professional, and individual Office apps
Product keys for one-time purchases of Office and individual Office apps are available at www.office.com/myaccount. However, you don't need a product key to reinstall or activate these products.

If you still want to view your product key, here's how:
-
Go to www.office.com/myaccount and sign in, if prompted.
-
Select your Office product.
-
Select View your product key. Note that this product key won't match the product key shown on an Office product key card or in the Microsoft Store for the same purchase. This is normal.
If you bought Office through Microsoft HUP
If you bought Office through your employer's Microsoft HUP benefit, you can also view your product key online on your Order Details page. For help, see Get your Microsoft HUP product key.
Can I view my key in the Microsoft Store?

My Office product key isn't working
If your Office product key doesn’t work, or has stopped working, you should contact the seller and request a refund. If you bought a product key separate from the software, it’s very possible the product key was stolen or otherwise fraudulently obtained, and subsequently blocked for use. Unfortunately, there are many dishonest sellers who offer stolen, abused, or otherwise unauthorized Microsoft product keys for sale. Sometimes these product keys are printed on counterfeit labels or cards with a download link to Microsoft software, and sometimes they’re distributed with software media that is unauthorized for resale, such as promotional media, original equipment manufacturer reinstallation media, or other Microsoft program-specific media.
