# Microsoft Office Product Key Activation Guide

## Introduction to Microsoft Office Product Keys

Microsoft Office product keys are essential for activating your software and unlocking its full functionality. These 25-character alphanumeric codes verify that your copy of Office is genuine and legally obtained. Whether you’ve purchased a retail version, subscribed to Office 365, or received Office through your organization, proper activation is crucial for continued access to all features.

## Where to Find Your Microsoft Office Key

Your product key location depends on how you acquired Microsoft Office:

– Retail purchases: Check the product packaging or card inside the box
– Digital purchases: Look in your email receipt or account purchase history
– Pre-installed versions: May be embedded in your device’s BIOS (for OEM versions)
– Volume licensing: Provided by your organization’s IT department

## Step-by-Step Activation Process

1. Open any Office application (Word, Excel, etc.)
2. Click “File” > “Account”
3. Select “Activate Product” or “Change Product Key”
4. Enter your 25-character Microsoft Office key
5. Follow the on-screen instructions to complete activation

### For Office 365 Subscriptions

– Ensure your internet connection is stable
– Check if you’ve reached the activation limit (typically 1-2 devices)
– Contact Microsoft Support if you receive error messages

## Important Considerations

– Always purchase Microsoft Office keys from authorized retailers
