Checking the validity on whether or not a number has been assigned can be easy if you know the highest number that has been assigned for any given "area number" (first 3 digits) for example:
If the highest number assigned in a given "area number" is XXX-09-5555, we know that based on the social security
administration's assignment order that number XXX-80-5555 in the same "area number", is not a valid number.
