How to Find Lost Product Key for Office 2013

"I want to transfer Microsoft Office 2013 Home and Student to another PC and while installing it, it's asking me for the product key. However, I have misplaced the product key and I'm also not registered online. Can someone please help me find the product key? I have purchased the licensed Microsoft Office 2013 software from a local vendor."

Microsoft Office 2013, like all version of Microsoft Office and most other paid software, requires that you enter a product key during the installation process. The Product key is something important that we need to always keep because it is a must whenever you install or reinstall the software. But sometimes you may don't keep the product key or you misplace it and now can't find it any more. If this is the case, don't worry, now here are a few methods that can help you find lost Office 2013 product key.

Method 1: Find Office 2013 product key from where you purchased it

If you purchased Microsoft Office 2013 as a disc in a box from a local vendor, or as a product card from a retail store, then your product key will be with the physical purchase — on the disc sleeve, on a sticker, on the product card, or in the manual. If you misplaced it, you may look for it on your computer desk drawer, or somewhere you usually store important materials.

If you purchased Office 2013 from Microsoft online, the product key should be stored in your Microsoft account online and arrived in your email receipt. Check your Inbox, Junk Mails, and Deleted Items to find the product key.
