Administrative territorial unit (ATU) authority table is a controlled vocabulary that lists concepts associated with various administrative territorial units of current and past EU Member States.
An administrative territorial unit is a portion of a country or other region delineated for the purpose of administration. Due to the large volume of lowest level administrative units (local authority, municipality) in certain countries, these units have not yet been fully implemented. ATU is structured by countries and contains labels in the official language(s) of the concerned country and in English.
The classification of each territorial unit can be found in the related Administrative territorial unit type authority table.
ATU is updated based on the stakeholders' needs.
Contributions to it are accepted following a review made by EU Vocabularies team of the Publications Office of the EU.
ATU is maintained by the Publications Office of the European Union and disseminated on the EU Vocabularies website.
