If you go here and do a find for 042-68 you'll see what purports to be the first part of Barack Obama's Social Security Number. According to the Social Security Administration, the 042 prefix indicates that the number was obtained in Connecticut: ssa.gov/employer/stateweb.htm
Obviously, there are a lot of open questions here, and even if that is his real number what exactly it would prove isn't clear.
The person who generated the list of names, addresses, and SSNs is apparently Neil Sankey (privateinvestigation.com), a former British policeman who's now a licensed private investigator in Los Angeles. A search here will show he has a clear record (actually, there are two records, one clear and one delinquent, with the latter probably just due to an address change; the clear one cancels out the other one).
If anyone can find some corroboration that that's really Obama's SSN, please leave a comment. Perhaps this is the real reason why he's so adamant about not releasing his college transcripts and the like.
UPDATE: As of late July 2009, this post is getting a lot of visitors. Could someone leave a comment explaining who mentioned this and when and where? Also, please see the Obama citizenship page for our extensive coverage of the wider issue.

What [licensed investigator from Ohio named Susan Daniels] and fellow investigator Neil Sankey unearthed was a nugget that could have ended the career of a George Bush or a Sarah Palin: Barack Obama had been using a Social Security number issued in Connecticut between 1977 and 1979, a state in which he never lived or even visited at that time in his life...
..."All I can say," says Daniels of 042-68-4425, "is that it's phony and [Obama] has been using it, with it first appearing on his Selective Service document in 1980."
Daniels sent me a copy of the hand-written application of the individual who held the number immediately before Obama's, 042-68-4424. The applicant, Thomas Wood, died at age 19, which is why his information is available.
Wood's Social Security number was issued sometime between March and May of 1977. Obama would turn 16 in August of that year. Wood lived on Glenview Drive in Newington, Conn., the state from which all "042s" applied. Obama lived in Hawaii...
..."Numbers are assigned based on the return address on the request envelope, not residency," crowed Jason Linkins in the Huffington Post as though he had said something meaningful. Linkins suggested two possible explanations, both preposterous...
