As more Social Security Numbers are leaked from security breaches like Equifax et al - I have done a deep dive into all things publicly known about SSNs and published the results on a hobby site (with limited ad revenue to cover the server cost) to both educate myself on the historic data contained in a social security number, how its usage has changed throughout the years (enumeration at birth in the 80's for example) and then how finally the state and date information was removed around 2009 so that numbers are now randomly assigned. For those born before the 2010 - there is a real information encoded (or deduced) from your number beyond what most are aware. If you are curious what types of information a hacker could deduce, or additional ways your SSN could be mis-used if disclosed (or guessed) take a gander at
