It is part of the Rheinische Post Mediengruppe which also owns newspapers like the Saarbrücker Zeitung, the Lausitzer Rundschau or the Trierischer Volksfreund.

There are 31 local editions, among them other regional newspapers, like the Neuß-Grevenbroicher Zeitung, the Benrather Tageblatt and the Bocholter-Borkener Volksblatt, which have their own regional news pages. The Rheinische Post is available at kiosks as well as through subscriptions. The paper is published in Rhenish format.
