Standard 2 of 5 (IATA 2 of 5)

Standard 2 of 5, also known as IATA 2 of 5, is a member of the Code 2 of 5 symbology family, which was first developed in 1968. It has been used by the International Air Transport Association (IATA) for the processing of airline cargo.

The spaces in a Standard 2 of 5 symbol are fixed-width, so that only the bars are used to encode information. The "2 of 5" name derives from the fact that of the five bars that are used to encode each character, two are wide and three are narrow.
