Get help redeeming your product key

Redeeming your product key is a one-time process that adds your new product to your Microsoft account. When you're done, you'll use your Microsoft account, not your product key, to install and activate your Office apps.

Note: If you have an existing Microsoft 365 subscription, you can redeem a new product key to extend your subscription.
