Australia Post 4-State barcode uses four types of bars (four states). This barcode can carry both numeric and alphabetic data in its Customer Information field, depending on the selected encoding.
The generator supports four barcode flavors: "Standard Customer Barcode", "Reply Paid Barcode", "Customer Barcode 2", "Customer Barcode 3". It also supports generation of Reed-Solomon error-correction codes.
This barcode generator allows you to specify type of the barcode to be generated (FCC field), a "Delivery Point Identifier" (mandatory parameter), a "Customer Information" field used for Customer Barcode 2 or 3 and type of encoding that should by applied to customer information.
