Original Prusa Serial Number

Every Original Prusa printer has a unique serial number assigned to it. This is found on a silver sticker on every machine (red square) and is also hardcoded to the main controller-board. Serial numbers issued before November 2021 start with "CZPX", while after November 2021 we introduced a new format starting with "SN". Stickers of both formats are located the same on Original Prusa printers. All serials are registered in our internal database and allows us to confirm your printer as genuine.

For some printer models, placing the serial sticker on the frame is part of the assembly process!

The best way to reference your printer is the order-number you received when purchasing the printer. This can be found on the invoice or in your order-history in the eshop.

Original Prusa MK-series

A label is found on the back of the frame (circled in red), above the PSU. 
 

Original Prusa SL1 & SL1S

A label is found on the back (circled in red), in the bottom-left. 
 
 

Original Prusa MINI & MINI+

A label is found on the Z-axis extrusion (circled in red), on the right side.
 
 

Hardcoded serial number

This requires a special application and commands, dependent on the printer, to extract. Nothing proprietary, but the procedure is rather advanced. If you really need to get the serial number this way, please email Customer support.
