Activating your Microsoft Office license key is essential to unlock all the features of the software. Whether you’re using Office 365 or a standalone version like Office 2019, this guide will walk you through the process step by step.

What is a Microsoft Office License Key?

A Microsoft Office license key is a 25-character code that verifies your copy of Office is genuine. This key is usually provided when you purchase Office online or with a physical product card.

How to Find Your License Key

Your license key can be found in different locations depending on how you purchased Office:

For digital purchases: Check your email confirmation from Microsoft

For retail purchases: Look on the product card inside the box

For pre-installed versions: The key might be stored in your computer’s BIOS

Step-by-Step Activation Process

1. Open Any Office Application

Launch Word, Excel, or any other Office program. If this is your first time opening it, you’ll see an activation prompt.

2. Sign In to Your Microsoft Account
