Microsoft Office Keys

About Office product keys

Microsoft Office license keys for Office 2024, 2021 and 2019, for Windows and Mac, plus Project and Visio.

Office 2024 or Office 2021?

Both are one-time purchases with Word, Excel, PowerPoint, Outlook, OneNote and Access. Office 2024 Professional Plus is the newest edition; Office 2021 Professional Plus also includes Publisher. Our Office 2024 vs 2021 comparison sets them side by side.

Windows or Mac?

Professional Plus editions run on Windows. For a Mac, choose Office Home & Business 2021 for Mac, which includes Word, Excel, PowerPoint, Outlook and OneNote.

One PC or five?

Each standard license covers one PC. The 5-PC versions of Office 2024 Professional Plus and Office 2021 Professional Plus cover up to five.

Is a one-time Office license a lifetime license?

In the sense most shoppers mean, yes: Office 2024, 2021 and 2019 are perpetual licenses. You pay once, the license does not expire, and the apps keep working on the computer where you activated them. Microsoft 365 is different: a subscription that runs for the term you buy.

Project and Visio

For plans and diagrams: Microsoft Project 2024 Professional and Visio 2024 Professional, or the 2021 editions.

Download and activation

Redeem the code on setup.office.com, install Office and open Word or Excel to finish activating it; Office 2024 Professional Plus installs with Microsoft’s Office Deployment Tool instead, as its guide shows. Every Office version is also listed on our Office ISO downloads page. One payment covers the license, nothing renews, and every order comes with a PDF invoice. Our support team helps 24/7 on live chat and by e-mail.
