How can I find out my Plesk Control Panel license key number on my Plesk installation?

• Parallels Plesk Panel for Linux/Unix
• Parallels Plesk Panel for Windows

Resolution

Parallels Plesk Panel for Linux/Unix:

Your Panel license number can be found on the License Management page in the Plesk Control Panel. Check the "Key number" field. It is also shown in the title bar of the browser window when you are logged into Panel CP as the "admin" user.

If the Control Panel is not accessible, you can log in to the server via SSH and learn the license number with the help of the following command:

1. Parallels Plesk Panel versions 7.x - 8.x:

# grep 'Key number' /etc/psa/psa.key
Key number: PLSK.01234567.0000

2. Parallels Plesk Panel version 9.x and higher:

# grep 'key-number' /etc/sw/keys/keys/key*
   <core:key-number core:type="string">PLSK.01234567</core:key-number>

Parallels Plesk Panel for Windows:

The license number can be retrieved using either of the following methods:

1. In the Plesk Control Panel, go to Server, License Management, and view the license number there.

2. Use this command in the command prompt:

"%plesk_bin%\keymng.exe" --get-key-number
PLSK.01234567.0000
