In this paper we will investigate the problem of finding the open-locating-dominating number for some classes of planar graphs-convex polytopes. We considered D n , T n , B n , C n , E n and R n classes of convex polytopes known from the literature. The exact values of open-locating-dominating number for D n and R n polytopes are presented, along with the upper bounds for T n , B n , C n , and E n polytopes
