How to retrieve a system serial number


The OnLogic serial number can be found on a label applied to the bottom of the system, or the rear of the display for Panel PCs. Our serial numbers will begin with U or E, followed by 6 digits.

Since 2018, OnLogic has written the serial number of the system into the SMBIOS data on all products. This means that the serial number can be retrieved without physically looking at the unit. This can be useful if the system is deployed in the field or mounted in an enclosure.


Open CMD from the start menu and run the following commands. One of them should return the correct serial.

WMIC BIOS get serialnumber
WMIC baseboard get serialnumber


Run the following commands in terminal.

dmidecode -s system-serial-number
cat /sys/devices/virtual/dmi/id/product_serial
