The first three numbers in your American Social Security Number do have a significance, believe it or not. They are an indication of where your number was filed. Take me, for example: I was born in Buffalo, New York on October 9, 1980. But before my parents could file for my SSN the family moved to Pennsylvania. So everyone else in my family has a New York number whereas I have a Pennsylvania number.

Without further delay, here is the table of numbers...

I am going to guess here and say that if a number range is listed below a state/territory with no assignment listed to the right, it belongs to the state or territory directly above it.
