The Länder have nine representatives at the CoR. The Gemeindebund and the Städtebund have a total of three representatives at the CoR (Article 23c(4) of the Constitution) and act on the basis of a rotation principle.

Regarding international matters, the federal government has exclusive competences. However, when it comes to EU matters that affect the competences of the Länder, the Länder may also become involved. Article 23d(3) of the Constitution makes it possible for Länder to represent Austria if it is a matter that is Länder business and if the Federal government decides to assign such tasks to the representative proposed by the Länder.

The Austrian Länder are represented in the Permanent Representation of Austria to the European Union with a Department for Länder and Regional Affairs, headed by a Länder civil servant.

Eight out of nine Länder have liaison offices established in Brussels. Only Vorarlberg does not have a representation office in Brussels.
