## Where to Find Your Office Key
Your product key can be found in several locations depending on how you purchased Office:
– Retail purchase: Check the product packaging or card inside
– Digital purchase: Look in your email confirmation or Microsoft account
– Pre-installed on a new device: Check with your device manufacturer
## Step-by-Step Activation Process
### 1. Install Microsoft Office
Begin by downloading and installing the Office suite from the official Microsoft website or using your installation media.
### 2. Launch an Office Application
Open any Office program like Word or Excel. You’ll be prompted to activate the software.
### 3. Enter Your Product Key
When prompted, carefully type your 25-character product key without spaces or dashes. The format should be: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

## Important Considerations
Always purchase Office product keys from authorized retailers to avoid counterfeit or already-used keys. Microsoft offers different versions of Office, so make sure your key matches the edition you’re trying to activate (Office 2019, Office 2021, Microsoft 365, etc.).
## Maintaining Your Activation
Once activated, your Office installation will remain valid unless you make significant hardware changes to your computer. For Microsoft 365 subscriptions, you’ll need to renew your subscription periodically to maintain access.
