Robert, The SSN has three parts: (1) area number, (2) group number and (3) chronological number, i.e., the last four are issued in numeric order.
It is possible that two men named John Jackson could have obtained an SSN from the same area and group, but because the last four digits are issued in chronological order, I wouldn't expect them to have the same SSN. I would imagine it is theoretically possible that two men named John Jackson could have similar numbers such as 475-62-1234 and 468-84-1234, but I'd consider the odds of that happening to be so small that it wouldn't be worth the worry. Again, I'm no expert on this subject; I'm only relating my understanding and it is on that understanding that I'd amend Mary's filing system for SSDI data.
