A combination-identifiable padlock has a shell, a combination lock cylinder, a key lock cylinder and an identification assembly. The combination lock cylinder, the key lock cylinder and the identification assembly are mounted in the shell. When the correct key is inserted, the key lock cylinder is rotatable to actuate the identification assembly and combination lock cylinder is actuated to identify the combination. Therefore, the combination is retrievable to avoid the combination lock cylinder to become unusable when the combination is forgotten.
