The number 666 is already on all of the bar codes used in the world. (there are two lines at the beginning, middle and end without any number written under them but they are the same as a 6 on the second half of codes with the number 6 in them.)
6 is two lines followed by 4 spaces, not just 2 lines. Google is your friend
