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 ...
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.

Barcode such as a Universal Product Code; QR code; Printing registration marks intended for the manufacturer of the packaging, to ensure different colors are aligned when printed; Various certification marks (see article for list) signifying conformance with a government or private organization's requirements
Codabar is a linear barcode symbology developed in 1972 by Pitney Bowes Corp. [1] It and its variants are also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Rationalized Codabar, ANSI/AIM BC3-1995 or USD-4.
In addition to 43 characters, Code 93 defines 5 special characters (including a start/stop character), which can be combined with other characters to unambiguously represent all 128 ASCII characters. In an open system, the minimum value of X dimension is 7.5 mils (0.19 mm). The minimum bar height is 15 percent of the symbol length or 0.25 ...
PDF417 is also used by the airline industry's Bar Coded Boarding Pass (BCBP) standard as the 2D bar code symbolism for paper boarding passes. PDF417 is the standard selected by the Department of Homeland Security as the machine readable zone technology for RealID compliant driver licenses and state issued identification cards.
x/S = Shift to mode x for one character; B/S = shift to 8-bit binary; x/L = Latch to mode x for following characters; Punct codes 2–5 encode two bytes each; The table lists ASCII characters, but it is the byte values that are encoded, even if a non-ASCII character set is in use; B/S (binary shift) is followed by a 5-bit length.
