Where do I need the sticker?
In the following cities, the PayByPhone app will automatically inform you that you also need a sticker:
Bergisch Gladbach, Berlin, Bernkastel-Kues, Bingen, Castrop-Rauxel, Detmold, Dortmund, Hamburg, Hanau, Kiel, Köln, Lemgo, Lübeck, Mainz, Potsdam
If you don’t have a parking sticker at hand, leave a note with the text “PayByPhone smartphone parking” clearly visible in the car instead. Without a sticker or note, you may get a parking ticket despite a valid pay and display ticket in these cities.
In all other PayByPhone cities, no sticker is required.
