Office 2021

Office 2021 keys for PC, all Professional Plus. Choose a RETAIL License for 1 PC, a RETAIL License for 5 PCs (one key activates 5 PCs), a CID License or a BIND License. RETAIL Licenses activate online, and we guide you if a Confirmation ID is needed. A CID License activates with a Confirmation ID through Microsoft’s activation portal. A BIND License is linked to your Microsoft account, so you can reinstall it or move it to a new device anytime.

Microsoft’s end-of-support date for Office 2021 is October 13, 2026: after that date, it gets no more security updates. For a newer version, see Office 2024 keys. Our guides cover the installation: How to Install and Activate Office 2021 Professional Plus via CID and How to Download and Install Office 2021 Professional Plus.
