Hi, When I first started receiving the list . I saw a posting on how the Social Security System was determined and how each state was given it's own code and series of identifying numbers I found it quite informative and useful. The only bad part is I didn't copy it and now it is gone from my memory. Would the person ,who posted it, as a point of information, Please, Please would you kindly post it again Thanking you in advance, Beatrice.
