Looks like you've got a base-36 number there (a-z + 0-9). Why not convert it to an int using Integer.parseInt(s, 36)? Obviously, if there are too many unique IDs, it won't fit into an int, but in that case you're out of luck with unique integers and will need to get by using String.hashCode(), which does its best to be close to unique.
