Question details

The user needs to know the correct place and method to enter an Office confirmation ID or a product key during the software activation process.

Where to Enter a Microsoft Office Confirmation ID or Product Key

Product: Microsoft Office
Device & OS: not provided
Scenario: Activating a newly purchased or reinstalled Microsoft Office application.
Observed behavior: The activation wizard is prompting the user for a confirmation ID, but the user may only have a 25-character product key, causing confusion about which activation method to use.

Before you start

Check the format of your code: a Product Key has 25 alphanumeric characters, whereas a Confirmation ID is a long numeric string provided specifically during the telephone activation process.

Solution 1Recommended

Enter the Product Key via Online Activation

Use this method if you have a standard 25-character product key and want to link it to your Microsoft account for automatic online activation.

If you bought a retail version of Office, you must redeem your product key online before attempting to activate the installed software.

Visit the setup portal

Open your web browser and navigate to setup.office.com.

Sign in to Microsoft

Enter the product key

Type your 25-character product key into the provided blank fields. The system will automatically format it with hyphens.

Complete setup

Select your country/region and language, then click 'Next' to add the Office license to your account.

Enter the Product Key via Online Activation

Activation Ready: Once redeemed online, you simply need to open any Office app (like Word) on your PC and sign in with the same Microsoft account to activate it.

Solution 2

Enter a Confirmation ID via Telephone Activation

Follow these steps if your screen specifically requests a Confirmation ID and you cannot activate Office online.

Frequently Asked Questions

Why does Microsoft Office ask for a confirmation ID instead of a product key?

Office prompts for a confirmation ID when you select the 'Activate by telephone' method in the Activation Wizard, usually because the software could not be activated over the internet. You must call Microsoft support to receive this specific ID.

Where can I find my 25-character product key?

Your product key is typically located on the receipt from an online purchase, printed on a card inside the physical Office box, or included in the confirmation email sent to you after buying a digital copy.

Is telephone activation still supported for all Office versions?

No, Microsoft has phased out telephone activation support for certain older versions of Office. If you receive an error stating the product is no longer supported for telephone activation, you may need to use online activation or upgrade to a newer software version.
