What can I do when my identity was stolen????

Seriously!!! when I tried to apply for a sears card and I put my personal information in the machine you use a pen with and someone elses name pops up! serious help or advice plz!!!!!. I'm really worried. Recently I lost my wallet too. and was lucky enough to get it back with everything inside including my indentity.
Is there a way to track it. Personally it has a lot to do with Gap letter I got about the thier laptop stolen!!

I would call all the companys you have cards with and tell them that your wallet was stolen and they can issue you new cards.

take information you have to the police ... identity theft is a crime

alas, police have all too much experience with it these days
