Campione (also known as Campione d'Italia), has a considerable amount of economic and administrative integration with Switzerland, using the Swiss Franc, and forming part of the Swiss customs union. Similarly, the telephone system is Swiss, meaning that calls require the international dialling code for Switzerland, e.g: 00 41 91 from Italy. Mail may be sent using either a Swiss postal code:
via volta 3 CH-6911 Campione d'Italiaor an Italian one:
via volta 3 I-22060 Campione d'ItaliaHowever, Campione takes advantage of its status by operating casinos, as gambling laws are less strict than in Switzerland, as well as allowing residence to those seeking to avoid Swiss taxes.
