Well currently I got my social security card stolen, I was wondering what can someone do with my ssn, date of birth and mothers maiden name?
And how do I find out if anyone is using it?
To find out if anyone is using your identity, pull your credit reports from Equifax, TransUnion, and Experian. See if any new account activity has been going on. Usually to open new lines of credit, one would need more information that that -- but there are, of course, ways for identity thieves to get that information as well.
