The public transportation network of the ZĂĽrcher Verkehrsverbund (ZVV) is divided into 45 fare zones covering Zurich, Switzerland, and nearby regions, mostly in the canton of Zurich. The fare zones (Tarifzonen) are numbered 110 to 184, with zones 180 to 184 designating those outside of the canton of Zurich (Aargau, Schwyz and St. Gallen), while zone 114 includes the southern part of the canton of Schaffhausen and zone 162 part of the canton of Thurgau. The city of Zurich corresponds to fare zone 110. The network covers a major portion of the Zurich metropolitan area.
Trips by tram/light rail, bus, fast and regional trains, such as InterCity (IC), InterRegio (IR), RegioExpress (RE), S-Bahn (S), even international trains (such as EuroCity Zürich HB–Munich), by any operator, are part of the fare network as long as the start and end of the journey both lie within the fare network's boundaries (see integrated ticketing). Passengers can use all modes of public transport within the fare zones covered by their ticket.
