They stopped reserving Social Security Numbers for individual states a while back.
Not that far back
it was still being done in the late 90s
Actually, since 1973 they have been using the state (actually zip code) to assign the first 3 digits.
Before 1973 the code did indicate what regional office it came from.
And that is still the process TODAY. Not a while back. It remains the process until later this year.

Attention All Users
On June 25, 2011, SSA will change the SSN assignment process. Numbers issued after this date will not adhere to the rules outlined on this page. Please see SSN Randomization for more information on SSA’s new assignment process and how it may affect you.
Since 1973, social security numbers have been issued by our central office. The first three (3) digits of a person’s social security number are determined by the ZIP Code of the mailing address shown on the application for a social security number. Prior to 1973, social security numbers were assigned by our field offices. The number merely established that his/her card was issued by one of our offices in that State.
