What about mail that goes to my old address?

The Postal Service will continue to deliver to your old address for a period of up to one year after you are issued a 9-1-1 address. It is your responsibility to contact everyone you correspond with to provide them your new address. This includes the tax office, banks, magazine subscriptions, utility companies, and all others that send you any mail. The United States Postal Service (USPS) has address change forms that may be used for this purpose.
