3.2 Barcode Types
The reason for the many different types of barcodes is that barcodes are used in many different
operational areas. Thus it is possible to select the most suitable barcode type to meet the
requirements of a particular industry.
3.2.1.1 Linear 1D Barcodes
Figure 1: Linear Barcode Sample
Linear barcodes are known under names like Code 39, Code 128, UPC, EAN, 2of5...
Linear barcodes encode the information in one way (=one dimension), so they are also called one-
dimensional barcodes (1D). The information is stored in the relationship of the widths of the bars
(spaces) to each other.
In most of these symbologies the height of the bars is not relevant, except for some height-
modulated Postal Codes (e.g. Australian Post 4-State or USPS OneCode).
3.2.1.2 2D Barcodes (Stacked)
Figure 2: 2D-Stacked Barcode Sample
Two-dimensional barcodes are known under names like PDF417, or Codablock F.
