You didn't try hard enough
There's what, 300 million people in the U.S.? They don't check your info against them all. Obviously the zip code has to be valid. Your first & last name can't contain numbers or wierd characters, date of birth is easy to fake. If they ask for a valid email, I just feed them the usual garbage and tack on "@yahoo" on the end. Piece of cake.
