A Microsoft Office product key is a 25-character code used to activate your Office suite.

• Retail purchase: Check the product packaging or the card inside the box
• Digital purchase: Look in your email confirmation or Microsoft account
• Pre-installed Office: The key might be embedded in your device’s BIOS
• Volume license: Contact your organization’s IT administrator
