Frequently Asked Questions

Why is the Costco PIN different from a Microsoft product key?

The Costco PIN is a proof of purchase code specific to the retailer. You must scan the accompanying QR code to verify the purchase through their portal and receive the actual 25-character Microsoft product key via email.

Where do I enter the Microsoft product key after I receive it?

Once you have the 25-character product key, go to office.com/setup in your web browser, sign in with your Microsoft account, and enter the key to link the software to your account and download the installer.

What if scanning the Costco QR code does not work?

If the QR code fails or you do not receive the email with the product key, contact Costco customer support directly to verify your purchase and request manual delivery of your redemption instructions.

Can I activate Office directly with the Costco PIN?

No, Microsoft Office cannot be activated directly with a Costco PIN. The PIN only serves to claim the actual Microsoft product key from the retailer's redemption portal.
