The NTIS sells this data (SSA death master record) as well... to folks inside and outside the US... 80 million plus records: http://www.ntis.gov/products/pages/ssa-death-master.asp

"Social Security says an erroneous death record can be removed only when it is presented with proof that the original record was entered in error."

WTF does this mean?

Maybe Google needs to take this over, too.

It means you could walk into their office with ID and prove you aren't dead?

I'm not sure I would be upset if the federal government thought I was dead. It would certainly save me a lot on my taxes.

Shouldn't updating a person's record to such a consequential state require double (or greater) data entry?

One would think so. But what if the error was in the paperwork from the funeral home?
