# Microsoft Office Product Key Activation Guide
What is an Office Product Key?
An Office product key is a 25-character code that comes with your Microsoft Office purchase. This key is essential for activating your software and verifying that you’re using a genuine, licensed version of Microsoft Office. The key typically looks like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.
