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.
The Code 16K (1988) is a multi-row bar code developed by Ted Williams at Laserlight Systems (USA) in 1992. In the US and France, the code is used in the electronics industry to identify chips and printed circuit boards. Medical applications in the USA are well known. Williams also developed Code 128, and the structure of 16K is based on Code 128.
Also like POSTNET, PLANET always starts and ends with a full bar (often called a guard rail), and each individual digit is represented by a set of five bars using a two-out-of-five code. [1] However, in POSTNET, the two bars are full bars; in PLANET, the two-of-five are the short bars.
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 ...
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.

Each black bar or white space can have a width between 1 and 4 areas. Parity for the digits from left and right group: OEOOEE EEEEEE (O = Odd parity, E = Even parity). The first digit in the EAN code: the combination of parities of the digits in the left group indirectly encodes the first digit 4. The complete EAN-13 code is thus: 4 003994 155486.
