Knowing how to check your Microsoft Office serial number can be important for a variety of reasons. For example, you may need it if you need to reinstall Office or if you want to transfer your Office license to a new computer. There are a few different ways to check your Office serial number, depending on which version of Office you have.
If you have a physical copy of Office, the serial number will be located on the back of the DVD case or on a sticker that is attached to the computer. If you purchased Office online, the serial number will be included in the confirmation email that you received from Microsoft.
