SSN is not unique!

• Bartweiss 10y ago
  Wait, what? Can you clarify? Obviously SSN is treated as secret when it isn't. I've heard noises about re-issuing SSNs from deceased people, but didn't think it had happened. But is it not unique among living citizens? That's huge and I've never heard of it.

    It appears that SSNs, as issued, are unique. But there are claims (which seem to be largely based from a study that some company called ID Analytics did about 10 years ago) that there may be millions of duplicate records because of identity theft, data entry errors, and people using the wrong number by accident.
