So far I only found that theSocial Security Death index allows to search by SSN but that's only for deceased people.

There are sites that claim you can search living people by SSN but is this true?

Can you find more information on someone (who's currently alive) if you have only his social security number?

The reason why ask is...well it's really a complicated situation it would take me another topic to explain

I've also taken a look at some private investigator services that promise to find a particular person by SSN but they're WAY too expensive ($2000+). There must be a way to do this online and I thought that you guys know best so that's why I decided to ask for your advice.

Best wishes,
