Barcode Scanning
Deutsche Post Identcode is used by the German postal system (Deutsche Post AG [DHL]) for mail routing. It is a variant of the Interleaved 2 of 5 symbology; only the check digit is different.
Symbol Structure
The symbol comprises the following elements:
Leading quiet zone
Start pattern (narrow bar, narrow space, narrow bar, narrow space)
One or more pairs of symbol characters that represent data (including an optional check digit)
Stop pattern (wide bar, narrow space, narrow bar)
Trailing quiet zone
Deutsche Post Identcode encodes a string of 11 or 12 digits, as follows:
Two-digit mail center distribution identifier
Three-digit customer code
Six-digit delivery identifier
One-digit check digit (optional)
Deutsche Post Identcode imposes a format on the human readable interpretation that includes periods (which are not part of the barcode symbol).
