Coloured_Postcode: Häuser und Straßen mit dem gleicher PLZ werden in einer Farbe dargestellt. Der CRC-Code der PLZ wird ab Version 2 dafür herangezogen. Postleitzahlengrenzen (boundary=postal_code) werden rot gestrichelt dargestellt. Straßen sollten mit postal_code=..... versehen sein (werden sonst rot markiert). Beachte den Unterschied zwischen ​addr:postcode und ​postal_code.
