What Is a Microsoft Office Product Key?

A Microsoft Office product key is a 25-character alphanumeric code that serves as a digital license for activating your Office software.

Product keys are typically required for both one-time purchases and subscription-based versions like Microsoft 365.

Depending on how you purchased Office, your product key may be located in one of the following places:

Digital Purchase: If you bought Office online from Microsoft or an authorized retailer, the product key is often sent to your email address.

Pre-installed on a Device: Some computers come with Office pre-installed. In this case, the product key is embedded in the device’s firmware and is automatically detected during activation.
