If you bought Office Home & Business, Office Professional, and individual Office apps

Product keys for one-time purchases of Office Home & Business, Office Professional, and individual Office apps are available at the Microsoft account, Services & subscriptions page. However, you don't need a product key to reinstall or activate these products. If these products are prompting you for a product key, you can sign in using the Microsoft account that you used to buy and download Office.

If you still want to view your product key, here's how:
  1. Go to the Microsoft account, Services & subscriptions page and sign in, if prompted.
  2. Select View 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 Professional Plus, Visio Professional, or Project Professional 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 HUP product key.

Can I view my key in the Microsoft Store?

If you bought Office Home & Student, Office Home & Business, Office Professional, or individual Office apps from the Microsoft Store and you haven't installed them yet, you can also view their product keys and install them from the Microsoft Store.

Here's how to view your product key in the Microsoft Store:
  1. Go to www.microsoftstore.com. In the upper right-hand corner, select Sign in and enter the user ID and password you used to buy Office.
  2. After you sign in, select your name in the upper right-hand corner, and then select Order History.
  3. Locate the Office one-time purchase or individual Office app, and then select Install Office to view your product key (this doesn't actually install Office). Note that this product key won't match the product key shown in the Microsoft account, Services & subscriptions page. This is normal.

My product keys don't match

This is normal. The Office product key shown on the Microsoft account, Services & subscriptions page will always be different than the product key that's shown on a product key card or email receipt. They are two different types of keys, even though they use the same format.

My Office product key isn't working

If you see an error message when you redeem your product key at Office.com/setup, see Get help with product key errors on Office.com/setup.

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.
