Linear Bar Code Symbologies
(6/93) ANSI/AIM BC2-1995, Uniform Symbology Specification - Interleaved 2 of 5
Interleaved 2 of 5 (also called I-2/5 and ITF) is suitable for encoding general purpose all-numeric data. Reference symbology for UCC/EAN Shipping Container Symbol. Character encodation, reference decode algorithm and optional check character calculation are included in this document. This specification is intended to be significantly identical to corresponding Commission for European Normalization (CEN) specification.
(6/93) ANSI/AIM BC1-1995, Uniform Symbology Specification - Code 39
Code 39 (Also Called Code 3 of 9) is suitable for encoding general purpose alphanumeric data. Reference symbology for many industry standards. Character encodation (standard and optional full ASCII), reference decode algorithm and optional check character calculation are included in this document. This specification is intended to be significantly identical to the corresponding Commission for European Normalization (CEN) specification.
(6/93) ANSI/AIM BC3-1995, Uniform Symbology Specification - Codabar
Codabar encodes all-numeric data and has four unique start/stop characters which can convey additional information. Character encodation (including traditional Codabar), reference decode algorithm and optional check character calculation are included in this document. This specification is intended to be significantly identical to the corresponding Commission for European Normalization (CEN) specification.
(6/93) ANSI/AIM BC4-1999, International Symbology Specification - Code 128
More condensed than Code 39, Code 128 is suitable for encoding general purpose alphanumeric and full ASCII data and provides high information density encodation of numeric data strings. A new feature permits encodation of extended ASCII for non-English language characters. Reference symbology for UCC/EAN Serial Shipping Container Symbol and all UCC/EAN secondary identification symbols employing application identifiers. Character encodation (code sets A, B, and C), reference decode algorithm and optional check character calculation are included in this document. This specification is intended to be significantly identical to the
corresponding Commission for European Normalization (CEN) specification.

(6/93) ANSI/AIM BC5-1995, Uniform Symbology Specification - Code 93
Code 93 offers higher information density for alphanumeric data than either Code 39 or Code 128. Character encodation (including full ASCII), reference decode algorithm and optional check character calculation are included in this document.
(12/97) ANSI/AIM BC12 Uniform Symbology Specification - Channel Code
Channel Code is a family of linear (one-dimensional) bar code symbols designed for encoding strings of 2 to 7 digits in the least symbol length possible. Reference decode algorithm and optional check calculation are included in this document. There are six defined sizes of the symbols. They range from "Channel 3" which can number up to 27 items in just 22 "X" of total symbol length up to "Channel 8" which can number up to 7,742,863 items in a space equivalent to 42 "X". There are also a number 'composite' symbol formats defined that offer enhanced capacity and/or security. Channel Code symbols can be made autodiscriminatable from many other symbologies, but they are not autodisriminatable from each other in a reliable manner. It is strongly recommended that applications using Channel Code select to use, and their readers be programmed to decode just a single channel or composite format.
Telepen
Telepen is a bar code symbology which enables the full 128 ASCII character set to be encoded. Additionally it offers a compressed numeric mode enabling numeric data to be encoded at twice the density of the standard mode. IT is a wide-narrow symbology with a fixed 3:1 wide:narrow ratio.
