A Swiss postal barcode encoding "RI 476 394 652 CH" in Code 128 (B & C) Code 128 is a high-density linear barcode symbology defined in ISO/IEC 15417:2007. [1] It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1.
encoding density moderate: barcode length on 11% longer than Interleaved 2 of 5 symbology and on 82% than Code 128; variable length of symbol; can include optional checking character. Four starting bars and spaces in pattern have own weights which encode value of the symbol (except zero). Also, last black bar is used as parity bit to avoid ...
The GS1-128 symbology is a subset of the more general Code 128 symbology. By agreement between AIM and GS1, use of the Function 1 Symbol Character (FNC1) in Code 128 symbols in the first symbol character position following the start character has been reserved exclusively for the GS1 system. Code 128 is fully described in ISO/IEC 15417

Codablock symbologies [16] [17] has been developed as a stacked version of Code 39 and Code 128 barcodes and has some advantages of 2D barcodes. They allow to utilize rectangular space more effectively then 1D barcode and have additional checking characters to ensure the content of the overall message.

IATA 2 of 5 [14] [15] (also known as Computer Identics 2 of 5, [16] Airline 2 of 5 [17] [18]) is a variable length, discrete, two width symbology, which is fully similar to Industrial 2 of 5 symbology except start/stop symbols. In this way it has all advantages and issues of Industrial 2 of 5 symbology.
