License Plate Number (LPN):
A unique identifier in a barcode (or RFID) form for a given handling unit – commonly a pallet – that is used to track that handling unit throughout its lifecycle. LPN barcodes can be pre-printed for use or printed on-demand as needed. In some scenarios, a pallet has an LPN, and individual cases on the pallet also carry LPNs, or there can be a master LPN on a pallet under which there are more than one LPN. In the latter scenario, the pallet might be put away as is, or the individual LPNs can be put away separately in different locations.
