For a graph G with vertex set V is a function f: V (G) →0. 1 with induced edge labeling such that f#: E (G) →0, 1 such that f# (pq) = (f (p) + f (q) ) (mod 2) for all pq \ (\) E (G) is called a sum cordial labeling, If |v (0) - v (1) |\ (\) 1 and |e (0) - e (1) |\ (\) 1. A graph that follows sum cordial labeling is called a sum cordial graph. We have proved that Vicsek fractal, Box fractal, Ladder Fractal Graph of Type – 1 to Type – 4 admits sum cordial labeling.
