Barcode Types & Symbologies vs. ISO Standard Pallet Sizes
Comparing 2 standards across 15 specifications. 15 key differences identified.
Machine-readable barcodes encode data in optical patterns regulated by GS1 and ISO/IEC into linear 1D barcodes (UPC-A, EAN-13, ITF-14, Code 128) and 2D matrix symbologies (QR Code, Data Matrix) for automated point-of-sale checkout and warehouse inventory tracking.
Standard shipping pallets are globally regulated under ISO 6780 into six standardized dimension footprints. The European EUR-1 pallet (800 × 1200 mm) and North American GMA pallet (48 × 40 inches / 1016 × 1219 mm) dominate over 80% of global automated warehousing and intermodal freight transport.
