Get help redeeming your product key

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

Note: If you have an existing Office 365 subscription and don't use recurring billing, you can redeem a new product key to renew your subscription.

Your browser does not support video. Install Microsoft Silverlight, Adobe Flash Player, or Internet Explorer 9.

To get started, remove your product key from your Office package, or gently scratch the silver foil on the back of your product key card. If you bought Office from the Microsoft Store, your product key is on your receipt.

Your product key is in a card in your product box or on the back of your product key card
