Key:uic_ref

UIC stands for Union Internationale des Chemins de fer, i.e. International Union of Railways. The UIC reference is used to identify railway stations in Asia, Europe and northern Africa. It is similar to the ICAO and IATA reference tag for airports.

The UIC station reference always consists of 7 digits, beginning with a 2-digit UIC country code.

Numbers of different length do not belong to the UIC system. They are used in the German HAFAS system to identify bus stops, or in France with an addtional 8th "control" digit, in which case a separate attribute may be used: ref:FR:uic8=*, see Liste des références nationales, while keeping the 7-digit uic_ref=*.
