Article 2
Structure 1. The NUTS classification subdivides the economic territory of the Member States, as defined in Decision 91/450/EEC, into territorial units. It ascribes to each territorial unit a specific code and name. 2. The NUTS classification is hierarchical. It subdivides each Member State into NUTS level 1 territorial units, each of which is subdivided into NUTS level 2 territorial units, these in turn each being subdivided into NUTS level 3 territorial units. 3. However, a particular territorial unit may be classified at several NUTS levels. 4. At the same NUTS level, two different territorial units in the same Member State may not be identified by the same name. If two territorial units in different Member States have the same name, the country identifier is added to the territorial units' names. 5. In each Member State, there can be further hierarchical levels of detail, decided by the Member State, whereby NUTS level 3 is subdivided. Within two years from the entry into force of this Regulation, the Commission, after consulting the Member States, shall submit a communication to the European Parliament and the Council on the appropriateness of establishing rules on a Europe-wide basis for more detailed levels in the NUTS classification.
