How to get your Confirmation ID

    In Microsoft Office or Windows, choose "Activate by phone". The wizard displays your Installation ID — 63 digits in nine groups labelled A through G.

  2. Enter your Installation ID above

    Type or paste the 63-digit Installation ID into the form. If we gave you a Tempcode in your purchase email, enter that too.

  3. Get your Confirmation ID instantly

    Click "Get CID". Copy the 48-digit Confirmation ID we return, paste it into the activation wizard, and your Microsoft product is activated.

What is a Microsoft Confirmation ID?

A Microsoft Confirmation ID is the 48-digit code Microsoft issues during telephone activation. When you choose "Activate by phone" in Microsoft Office or Windows, the wizard displays a 63-digit Installation ID and asks for a Confirmation ID in return. Typing that CID into the wizard activates your license and unlocks the product permanently — no subscription, no internet connection required at activation.

This generator returns a valid Confirmation ID instantly for any genuine Microsoft license, including Microsoft Office 2010, 2013, 2016, 2019, 2021, and 2024, Project, Visio, and Windows 7, 8, 10, and 11.

Frequently asked questions

What is a Microsoft Confirmation ID (CID)?

A Microsoft Confirmation ID (CID) is a unique 48-digit code Microsoft generates during telephone activation of Microsoft Office and Windows. You receive a CID after providing your Installation ID, and entering it into the activation wizard completes the activation of your license.

When do I need a Confirmation ID?

You need a Confirmation ID whenever you activate Microsoft Office (2010, 2013, 2016, 2019, 2021, or 2024) or Windows (7, 8, 10, or 11) by phone — typically when online activation fails, when you reinstall on the same machine, or when you bought a phone-activation license. Microsoft 365 subscriptions do not use a CID; they sign in online instead.

Where do I find my Installation ID in Microsoft Office?

Open any Office app, go to File → Account → Activate Product → I want to activate the software by telephone. The activation wizard displays your 63-digit Installation ID in nine groups labelled A through G. Copy the digits exactly and paste them into the form above.

Where do I find my Installation ID in Windows?

Press Windows + R, type slui.exe 4, then press Enter. Choose your country and the activation wizard shows your Installation ID. The same flow works on Windows 7, 8, 10, and 11.

Where can I find my Tempcode?

Your Tempcode is included in the order confirmation email we sent to the address you used at checkout — printed right next to your product key. If you cannot find it, contact our support team and we will resend it.

Is this Confirmation ID service free?

Yes. CID generation is included free with every Microsoft license purchased from us. We do not charge per activation; the service is part of the support we provide to our customers.

Does the CID generator work for all Microsoft products?

It works for Microsoft Office (2010, 2013, 2016, 2019, 2021, 2024), Office Standard and Professional Plus editions, Project, Visio, and Windows (7, 8, 10, 11). It does not generate codes for Microsoft 365 subscriptions, which activate through online sign-in rather than telephone activation.

I did not receive a Confirmation ID — what should I do?

The most common cause is a mistyped Installation ID. Re-check every digit in groups A through G, then try again. If the wizard reports the key was already activated too many times, your license may need a manual review — contact our support team and we will investigate.

How long is a Microsoft Confirmation ID?

A Microsoft CID is 48 digits long, displayed in eight groups of six digits separated by dashes (e.g. 178094-888602-241891-962655-518483-094574-889315-694584). Enter it exactly as shown into the telephone activation wizard.
