Each Member State with at least two EETS domains on its territory shall designate a single contact office for EETS providers. The Member State shall make public the contact details of that office, and provide them, upon request, to interested EETS providers. The Member State shall take the measures necessary to ensure that, upon request of the EETS provider, the contact office facilitates and coordinates early administrative contacts between the EETS provider and the toll chargers responsible for the EETS domains on the territory of the Member State. The contact office may be a natural person or a public or a private body.
