In the theory of codes, it is known that the language {x,y} is a code if and only if  xy != yx. In 2004, Zheng-Zhu Li, Y.S. Tsai and Gian-Chi Yih provided a characterization for codes consisting of three words in Fibonacci languages. In this paper, we present some results of codes with three elements in the Fibonacci languages. Then we give a characterization on codes with four elements in Fibonacci languages.
