Technical Specifications
The first digit identifies the number system (0=regular, 2=random weight items, 3=drugs/health, etc.). Digits 2-6 identify the manufacturer, 7-11 identify the product, and digit 12 is the checksum. Quiet zones of 9X (left) and 9X (right) are required. UPC-A is a subset of EAN-13 (add a leading 0).
