Whether you’ve purchased a retail copy or received a key through your organization, this guide will walk you through the activation steps.

## What is an Office 365 Product Key?

An Office 365 product key is a 25-character code that comes in the format XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. This alphanumeric code serves as proof of purchase and is required to activate your subscription. Product keys can be found:

Before activating your Office 365 key, ensure you have:

– A stable internet connection
– A Microsoft account (or work/school account for business versions)
– The product key ready (keep it confidential)
– System requirements met for Office 365

## Step-by-Step Activation Process

### Step 1: Sign In to Your Microsoft Account

Visit office.com/setup and sign in with your Microsoft account. If you don’t have one, you’ll need to create it during this process.

### Step 2: Enter Your Product Key

Once signed in, you’ll be prompted to enter your 25-character Office 365 key. Type it carefully without dashes or spaces, as the system will automatically format it.

### Step 3: Verify Your Subscription

After entering the key, Microsoft will verify your subscription type and duration. Confirm that the details match what you purchased.

### Step 4: Download and Install Office 365

Select your preferred language and click “Install” to begin downloading the Office suite. The installer will guide you through the installation process.
