NUTS-2 regions

Main article: NUTS of Switzerland

As a member of the EFTA, Switzerland is included in the Nomenclature of Territorial Units for Statistics (NUTS). The three NUTS levels are:

NUTS-1: Switzerland (CH0)
NUTS-2: 7 Regions
NUTS-3: 26 Cantons

The seven NUTS-2 regions are the following:

Code	Region	Region (local name)	Cantons
CH01	Lake Geneva region	Région lémanique	Vaud, Valais, Geneva
CH02	Espace Mittelland	Espace Mittelland	Berne, Fribourg, Solothurn, Neuchâtel, Jura
CH03	Northwestern Switzerland	Nordwestschweiz	Basel-City, Basel-Country, Aargau
CH04	Zurich	Zürich	Zurich
CH05	Eastern Switzerland	Ostschweiz	Glarus, Schaffhausen, Appenzell Ausserrhoden, Appenzell Innerrhoden, St. Gallen, Grisons, Thurgau
CH06	Central Switzerland	Zentralschweiz	Lucerne, Uri, Schwyz, Obwalden, Nidwalden, Zug
CH07	Ticino	Ticino	Ticino

Below the NUTS levels, there are two LAU levels (LAU-1: districts; LAU-2: municipalities).

The two-letter abbreviations are widely used, e.g. on car license plates and as disambiguator for localities on postal addresses if two localities in different cantons have the same name. They are also used with the prefix "CH-" as ISO 3166-2 codes of Switzerland, e.g. CH-SZ for the canton of Schwyz.

SFSO also uses a numerical code ordering the cantons by their constitutional order (1 to 26).

The FIPS 10-4 region codes of Switzerland were used by the United States government. This standard was withdrawn in 2008.

The NUTS-3 codes are used by the European Union.
