# Office 2021 Product Key Activation Guide

## Introduction to Office 2021

Microsoft Office 2021 is the latest standalone version of the popular productivity suite. Unlike Office 365, which requires a subscription, Office 2021 offers a one-time purchase with perpetual licensing. To use all features of Office 2021, you’ll need a valid product key for activation.

## Where to Find Your Office 2021 Key

Your Office 2021 product key can be found in several places depending on how you purchased the software:

– Retail purchase: Check the product card inside the physical box
– Digital purchase: Look in your email confirmation or Microsoft account
– Volume licensing: Contact your organization’s IT administrator

## Step-by-Step Activation Process

## Frequently Asked Questions

### Can I use my Office 2021 key on multiple computers?

No, a standard Office 2021 product key is licensed for use on a single computer. You would need additional licenses for multiple devices.

### What if I lose my product key?

If you purchased digitally, check your Microsoft account or email receipt. For retail purchases without proof of purchase, you may need to buy a new license.

### Does Office 2021 require internet for activation?

An internet connection is required for initial activation, but once activated, most features work offline.
