If you have physical access to the host or remote access to the direct console, you can use the direct console to access the ESXi license key.


  • From the direct console, select View Support Information.
    The license key appears in the form XXXXX-XXXXX-XXXXX-XXXXX-XXXXX, labeled License Serial Number.
    Note: The physical machine serial number also appears, labeled Serial Number. Do not confuse the license key with the physical machine serial number.
