Effective June 25, , the SSA began a new randomized assignment methodology, called "SSN Randomization", in an effort to extend the longevity of the nine-digit SSN nationwide as well as for security since randomization makes the newly assigned SSN's more difficult to reconstruct using public information.

Unused area numbers previously assigned to states, as well as previously unassigned area numbers, will now be available in the new randomization system. Numbers in red were originally assigned to these states but were subsequently unassigned come June and used in the new randomized assignment.

Numbers in these "officially" unissued series may still have been issued for applicants in these states prior to randomization. Social Security Numbers are never reassigned after someone dies. Despite issuing over million SSN's since , and assigning about 5.
