Frequently Asked Questions

Do I need to include hyphens when entering my Office product key?

No, you do not need to type the hyphens. The setup website (setup.office.com) automatically formats the 25-character key as you type it into the boxes.

Where can I find my Office product key if I bought it online?

If you purchased Office Home & Student digitally, the product key is usually found in your purchase confirmation email or within the digital purchases section on the retailer's website.

What should I do if my product key has already been used?

If an error says the key is already used, it means the license is already linked to a Microsoft account. Go to account.microsoft.com/services and log in with the email you originally used to redeem it.

Why is my new laptop asking for a product key for Office?

If your laptop included a bundled Office license, it is likely a digital license linked to your device's motherboard. Open an Office app and log in with your Microsoft account to activate it; it usually won't require a manual key entry.
