Code 128, described in ISO/IEC 15417, is good at encoding alpha-numeric data and numeric-only data. Code128 has three subsets: code128A, code128B and code128C.
Code 128A is used to encode uppercase alpha and control characters.
Code 128B is used to encode both uppercase and lowercase alpha and numeric data.
Code 128C is used to encode numeric-only data.
Code 128 has many variations, such as EAN 128 and ISBT 128. Since 2004, use of UCC/EAN Code128 symbology is mandatory for printing barcode labels of Confirmation Services. USS Code128 also uses subset C to print barcode.
