Introduction

The I-2 of 5 barcode forms the basis of the German Identcode and Leitcode symbols used by Deutschen Post. These are 12 and 14 digit barcodes respectively, but they do use a different check digit calculation from the standard I-2 of 5 symbol.

Note that spaces and periods are removed from the strings supplied for I-2 of 5 barcodes before the barcode image is created – so the correct layout for Identcode and Leitcode text may be used to create the symbols.
