A compact GS1 symbology designed to fit on small or irregularly shaped items like fresh produce, coupons, and pharmacy packaging. GS1 DataBar encodes a full 14-digit GTIN in a space significantly smaller than EAN-13, enabling point-of-sale identification on items previously too small for barcoding.
