    Answer:

    55440 codes.

    Step-by-step explanation:

    There are 11 characters to choose from and the codes is 5 characters long.

    The total number of possible codes is the number of permutations of 5 from 11

    = 11P5  

    = 11! / (11 – 5)!

    = 11! / 6!

    = 11*10*9*8*7

    = 55440.
