The municipality, a rural residential community, lies in the central Hunsrück in a gently sloping location at the Simmerbach valley.

Archaeological finds show that the area was settled in the New Stone Age, or in the time of the Hunsrück-Eifel Culture.

The village belonged to the Duchy of Palatinate-Simmern, which introduced the Reformation in 1556.

Beginning in 1794, Oppertshausen lay under French rule.

The 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.
