Phone Activation
Clear guide + free Confirmation ID tool for Microsoft licenses that require phone activation.
Step-by-step guide
Follow these steps when Windows asks you to activate by phone.
01Start phone activation
On the PC, open the phone activation screen (or dial the Microsoft activation number shown). You will see a long Installation ID (IID).
02Copy the Installation ID
Copy the full IID carefully — digits only, no missing blocks. Paste it into the tool on this page (one ID per line if you have several).
03Get Confirmation ID
Click Run. We generate the Confirmation ID (CID) you need. Copy it with one click.
04Enter the Confirmation ID
Type or paste the CID into the phone activation screen (or tell it to the automated system). Activation should complete within seconds.
Good to know
- Online activation keys do not need this tool — use them with an internet connection.
- If CID generation fails, double-check the IID blocks and try Status check mode.
- Keep your product key safe; phone activation is only the confirmation step.
- You can process up to 5 Installation IDs per request, free of charge.
Get Confirmation ID
Paste the Installation ID from the phone activation screen — we return the Confirmation ID.
This tool is for phone-activated Microsoft licenses. Online keys do not need a Confirmation ID.
