A divisor cordial labeling of graph G with vertex set V is bijection from V to {1,2,……..V(G)} such that if each edge uv is assigned the label 1 if f(u)/ f(v) or f(v)/f(u) and 0 otherwise, then the number of edges labeled with 0 and the number of edges labeled with 1 differ by atmost 1. A graph which admits divisor cordial labeling is the divisor cordial graph. In this paper, it is proved that Shell(Fn),Umberlla( U(n,3) ),Wheel(Wn ),Globe(Gl(n) )are divisor cordial graphs.
