Barcode Symbologies

A barcode symbology is the encoding scheme that is used to express data by using a pattern of bars and spaces in a barcode. The bars and spaces are the most basic elements of a barcode, and their arrangement is defined by the symbology that is used.

Symbologies can be divided into four categories based on technical specifications and one based on application specifications:

ClosedLinear Symbologies

Closed2-D Stacked Symbologies

Closed2-D Matrix Symbologies

ClosedComposite Symbologies

ClosedApplication Standards
