In this paper, some existing theories on convergence of fuzzy number sequences are extended to
I
2
-statistical convergence of fuzzy number sequence. Also, we broaden the notions of
I
-statistical limit points and
I
-statistical cluster points of a sequence of fuzzy numbers to
I
2
-statistical limit points and
I
2
-statistical cluster points of a double sequence of fuzzy numbers. Also, the researchers focus on important fundamental features of the set of all
I
2
-statistical cluster points and the set of all
I
2
-statistical limit points of a double sequence of fuzzy numbers and examine the relationship between them.
