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.
