Hi,
A Product Key is a 25-character code used to activate and verify your Office license. It is used to confirm that you own the product and let you use all its features. The Product ID, on the other hand, is a unique code for each installation and is mainly used for support or troubleshooting. It is not used to activate Office or any other app.
