Not to worry. I got ID frauded about 12 years ago. All they needed was my name and address from the phone book.
They made a phony check and wrote it to a Walmart in Charlotte. The police called me and asked me if I wrote it.
I told him I've never been there in my life and had no account in that bank. Filled out an affidavit of fraud.
Put a lawn sprinkler near your porch.
When hapless Census guy comes to the door, say wait a minute, run out the back and turn on the faucet.
They wont be back again!
