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 .
[9] [10] Codablock A was based on stacked Code 39 barcodes and wasn’t widely used because of Code 39 restrictions. The next Codablock F [11] [12] was based on stacked Code 128 symbology and was standardized as AIM standard in 1995.

Williams also developed Code 128, and the structure of 16K is based on Code 128. Not coincidentally, 128 squared happened to equal 16,384 or 16K for short. Code 16K resolved an inherent problem with Code 49. Code 49's structure requires a large amount of memory for encoding and decoding tables and algorithms. 16K is a stacked symbology. [41] [42]
Code 128 is a Uniform Symbology Specification (USS Code 128) alphanumeric bar code that encodes text, numbers, numerous functions, and designed to encode all 128 ASCII characters (ASCII 0 to ASCII 127), as used in the shipping industry. Subdivisions include: 128A (0–9, A–Z, ASCII control codes, special characters)
DotCode barcode was invented in 2008 [1] by Dr. Andrew Longacre from Hand Held Products company and standardized in 2009 [6] by AIM as “Bar code symbology specification - DotCode”. [7] In 2019 DotCode was reviewed as “ISS DotCode Symbology Specification 4.0”. [2] Set of patents is registered, which are related with DotCode encoding and ...

Code 39 (also known as Alpha39, Code 3 of 9, Code 3/9, Type 39, USS Code 39, or USD-3) is a variable length, discrete barcode symbology defined in ISO/IEC 16388:2007. The Code 39 specification defines 43 characters, consisting of uppercase letters (A through Z), numeric digits (0 through 9) and a number of special characters ...
