When an SSN was issued under the pre-1973 field office (FO) SSN assignment procedures,
                  some shipments were occasionally lost in transit, fire, or flood before Central Office
                  (CO) could establish the records. For these situations, CO established the related
                  records as “VOID”, subject to reestablishment of the identifying information on the
                  record when and if SSA eventually determines to whom a particular SSN was assigned.
