The problem being if you know the last four and their birthday and where they were born you can recreate their full ssn.

The first 3 numbers are tied to specific geographic areas. The middle two are based on when you were born. The last 4 are a unique number.

So theoretically you can get their social by finding their place of birth and date- after you get the special 4 digits?
