With the exception of Oberkollbach, which grew substantially in the 1960s and 1970s, there was not much development in the modern municipal area after World War II.

[3] The municipality (Gemeinde) of Oberreichenbach is situated in the district of Calw, in Baden-Württemberg, one of the 16 States of the Federal Republic of Germany.

[3] Population development:[4] Oberreichenbach has four boroughs (Ortsteile), Igelsloch, Oberkollbach, Obrerreichenbach, and Würzbach, and four villages: Kunstmühle, Naislach, Siehdichfür, Unterkollbach.

In addition, the minor administrative unit of Eberspiel and the abandoned village of Oberwürzbach are found in the municipal area.

The wavy fess is a reference to the names Oberreichenbach, Oberkollbach, Würzbach, and Unterkollbach, as bach means "stream" in German.
