Two out of every five bars or spaces are wide, giving the name "2 of 5", and each pair has a consistent width. The wide lines form a two-out-of-five code with consecutive values of 1, 2, 4, 7, and 0, where the code 0 is assigned to the value of 11. This is similar to the POSTNET bar code. Digits 01 23 45 67 89 encoded in ITF: a = quiet zones
IATA 2 of 5: Discrete: Two: IATA 2 of 5 version of Industrial 2 of 5 is used by International Air Transport Association had fixed 17 digits length with 16 valuable package identification digit and 17-th check digit. Industrial 2 of 5: Discrete: Two: Industrial 2 of 5 can encode only digits 0–9 and at this time has only historical value. ITF ...
For full Aztec codes, the number of layers is encoded in 5 bits, and the number of data codewords is encoded in 11 bits, making a 16-bit mode word. The mode word is broken into two or four 4-bit codewords in GF(16) , and 5 or 6 Reed–Solomon check words are appended, making a 28- or 40-bit mode message, which is wrapped in a 1-pixel layer ...
The data codewords in 0 – 112 range are encoded in 5-of-9 binary dot patterns [2]: 5.2 which are encoded from 9 dots where 5 black dots and 4 white spaces. The rest of barcode matrix (rest from division on 9) is padded with black padding bits. [2]: 5.2.3 The padding bits can be from 0 to 8. The logically DotCode bits array is represented as:
A single 1 would be the thinnest line in the bar code. Three 1's in sequence (111) indicates a bar three times as thick as a single 1 bar. There are 108 possible 11-unit wide symbols, and the code uses all possible symbols. Two of the symbols are used for stop (end-of-barcode) indication, stop and reverse stop.

A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...
Because there are only six letters in the Letters(+30) group (letters 30–35, or U–Z), the other four positions in this group (36–39) are used to represent three symbols (dash, period, space) as well as the start/stop character. The two wide bars, out of five possible positions, encode a number between 1 and 10 using a two-out-of-five code ...
