Vienna’s postal codes refer to the Bezirk (district). ‘1010’
therefore stands for the first district, and ‘1200’ for district
number 20.
Opening hours of post offices: Monday-Friday 8am-12am, 2pm-6pm,
Saturday 10am-12am. The main post office is at Fleischmarkt 19
(Underground: Schwedenplatz). It is open all day and night just like its
branches at Süd-, West- en Franz-Josephs-Bahnhof (railway station).
