About Barcode Generator
Understanding Barcode Formats
Code 128 is the universal standard for shipping labels, logistics, packaging, and internal inventory tracking because it encodes all 128 ASCII characters with high density.
EAN-13 and UPC-A are global retail barcodes. UPC-A is predominantly used in North America (12 digits), while EAN-13 is used worldwide (13 digits). Both require strict mathematical check-digit algorithms to ensure scanners do not read damaged labels incorrectly.
