IGuard your trash from theft by shredding documents and receipts. Thieves can build an alternate identity using the mail you throw away. 3 Always check your monthly statements. (Criminals will sometimes make a small purchase first, to see if it goes undetected, before making a big one.) 2 Don't leave credit cards in glove compartments. (Glove compartments account for thousands of credit card thefts.) 4 Notify the post office immediately if you change your address. Mail going to your old address can end up in the wrong hands.
