NACE is the Statistical Classification of Economic Activities in the European Community (in French: Nomenclature statistique des activités économiques dans la Communauté européenne). It is part of the international integrated system of economic classifications, based on classifications of the UN Statistical Commission (UNSTAT), Eurostat as well as national classifications.
NACE consists of a 6 digit code. The first four digits of the code, which is the first four levels of the classification system, are the same in all European countries. The fifth digit might vary from country to country and further digits are sometimes placed by suppliers of databases.
