                         This is my attempt to find out valid german postal codes (PLZ or Postleitzahlen).
After the German Unification the numbers were changed to a five digit system. The postal codes starts with the two digit "Leitzahl". This is a number between 00 and 99 excluding the  not yet used numbers: 00, 05, 43 and 62! After that follows directly a three digit number, 000-999.
Comments welcome. This works for me, however I think it could be written more compact, but could not figure out how ;-)
