When I arrived in the US in 1971 and was issued my SSN# it was explained to me that the 1st few numbers identified the state that the number was issued from
Correct.
Hey Kleon you listening?
In fact the initial 3 digits indicate the zip coded area that begins with those same digits. I don’t know what they do now that such areas can have originated more than a million SSNs since the beginning of Social Security in some cases. Adding more digits to the SSN will be an upheaval like unto the Y2K panic.
Yes, but not necessarily the state in which you reside.
