Postal Codes in Vienna
Postal codes determined by districts
Postal codes of places in Vienna are determined by the district where that place lies. Austrian postal codes have four digits. For Vienna the first digit is always 1. The following two digits are exactly the district number (for districts 1-9 the second digit in the postal code is the leading zero). The last digit in the postal code is usually zero in Vienna. As a result for example Innere Stadt (first district) has the postal code A-1010 and Meidling (12th district) has A-1120.
Exceptions to the rule
There are some exceptions to these district-based postal codes. Vienna International Airport located in fact outside the area of Vienna in the state of Lower Austria has a Viennese (but not district-based) postal code 1300. Vienna International Centre (usually called UNO City) has 1400, thought it is situated in the 22th district (Donaustadt). Similarly, Austrian United Nations Peace-Keeping Forces have 1500.
