Barcodes with iOS: Bringing together the digital and physical worlds (2015)
Appendix C. GS1-128 application identifiers
GS1 maintains the GS1-128 standard, which defines the semantics for use on top of Code 128 encoding. GS1-128 barcodes—found on more and more products—can contain a great variety of data. Each piece of information is tagged with an application identifier specifying its semantic meaning. Table C.1 lists the various application identifiers.

This list specifies the decimal position in numbers in an interesting way. For example, 310y is the application identifier for product net weight in kg. The y can be any digit from 0 to 9, and the integer that follows is to be divided by 10 to the power of y. For example, a net weight of 22.7 kg could be coded as 3101 000227, 3102 002270, 3103 022700, or 3104 227000.
