But if you were born before 1998 (1999?), it's not necessarily easily reverse engineer-able. You need to know where someone lived when they first got a job. I've gotten into many arguments that given the first five digits of my SSN, someone can tell me where I was born. Prior to the IRS requiring a SSN for claiming dependents, many people did not get a SSN until they started working; parents did not apply for them at birth. Most of the people I went to high school with, got them in high school.
