 The arms were approved by the Rheinhessen-Pfalz "Regierungsbezirk" administration in Neustadt an der Weinstraße on 26 February 1980.The charge on the sinister (armsbearer's left, viewer's right) side is drawn from the arms once borne by Electoral Palatinate, which was once Nanzdiezweiler's overlord.The silver endorse (a slim variant of a pale) on the dexter (armsbearer's right, viewer's left) side refers to the Counts of Leyen, to whom Dietschweiler and Nanzweiler once belonged.
