The highest placeholder in a 4-digit number is the thousands place. You would want the smallest value in this place. If it was a zero, then it's not really a 4-digit number, anymore. The other places should also have the smallest numbers possible, but now you can use zeros, and it remain a 4-digit number. Or you could just say, that if you subtract 1 from 1000 you now have 999 which is no longer a 4-digit number.
