The 25 digit product key is on a yellow sticker on the inside of the DVD case. If you used the PIN, your product key may have been stored on your account page. If you have not used it, go to and enter your PIN to get your product key. If Office came with a box or card, look on the card or packaging. I bought Office without a DVD at a physical store. Or search your inbox for an email from your Order History page for information on how to contact Support.
Go to your Account page and click Digital Content. If you still can’t find your product key, contact the seller to ask for the link or receipt to be resent. Try logging into the site where you purchased Office to check your order details. If you didn’t get a receipt, check your junk mail folder. The product key should be in your email receipt. I downloaded Office from an online store. Tip: If your copy of Office came with a PIN instead of a product key, go to and enter your PIN to get your product key.
