How to Find a Microsoft Word Product Key

by Filonia LeChat

Software companies license their products with a layer of security called a product key (sometimes called a license key, license ID or product ID). This is a string of numbers (and sometimes letters) specific to that software, which demonstrates your valid ownership of the product. After you've installed your software, such as Microsoft Word, you can find and review your product key within the software itself.

Step 1

Open Microsoft Word and click the "File" tab at the top of the screen.

Step 2

Click the "Help" option in the column on the left side of the screen.

Read the product ID, a string of four sets of numbers divided by hyphens (-), on the middle of the screen, located under the large logo for "Microsoft Office" and under the "About Microsoft Word" section.


  • Your Microsoft Word product key is also available on the software package itself. It may be on the installation CD, on the box or on a paper insert included inside the box.
