If your purchase of an Office product came with a 25 character product key, you can use the steps below based on which product you have to find out where you should enter that key to download and install your Office product. 

Example of an Office product key:

XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

Office 365, Office 2019, Office 2016, and Office 2013 (PC and Mac)

To redeem a new purchase of Office

1. Go to www.office.com/setup
2. Sign in with your Microsoft account, or create one if you don't have one. Be sure to remember this account so that you can install or reinstall Office later, without a product key.
3. Enter your Office product key, without hyphens, if prompted. If you don't see the option to enter your product key, it was entered for you automatically.
4. Follow the prompts to finish the redemption process.
