Carton identification codes give each shipping unit a unique, machine-readable identifier – a barcode, QR code, or RFID tag – enabling automated scanning at every point in the supply chain, from palletizing stations to warehouses and transfer hubs. Each scan links the physical unit to a digital record in a warehouse management or transport system, providing real-time visibility and genuine traceability. In cross-border shipments, such codes are frequently required for electronic customs declarations and compliance with traceability regulations. A key distinction exists between proprietary in-house codes and open industry standards such as GS1-128, which retailers and logistics networks commonly mandate as a contractual requirement.
