Kommen belongs to the Verbandsgemeinde of Bernkastel-Kues, whose seat is in the like-named town.

The municipal council is made up of 6 council members, who were elected by majority vote at the municipal election held on 7 June 2009, and the honorary mayor as chairman.

[3] The municipality's arms might be described thus: Argent a chevron reversed gules, the ends in chief and the point at the base, surmounted on each side by a scythe blade of the field, the points to base.

The reversed (that is, upside down) chevron forms a V, which is meant to stand for the village's patron saint, Valentine, and the scythe blades refer to the agriculture that is the villagers’ main livelihood even today.

Public transport in Kommen is integrated into the Verkehrsverbund Region Trier (VRT), whose fares therefore apply.
