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.
