Do not use your home mailbox to send mail. Always either use a U.S. Post Office mailbox or go to the post office itself to send your outgoing mail, since a favorite way of obtaining credit card numbers and bank account numbers is by stealing outgoing mail from people’s houses. Keep track of your incoming mail. If you find that you are not receiving mail, check with your post office to make sure no one has filed a change of address form for your address. Also, reduce your incoming mail by using more of the online, paperless billing offered by most of your service providers, like your credit cards and utility bills. When you send checks for your bills, make sure the check is hidden, so that the account information on the check is concealed in the envelope.
