The Maine Notice of Change of Address is a form used to notify the State of Maine when an individual's address has changed. This form is used to update both the Bureau of Motor Vehicles (BMV) and the Division of Motor Vehicles (DMV). It is important to update the state of Maine when changing your address as this will ensure that your driver's license, vehicle registration, and other important mailings are sent to the correct address. There are two types of Maine Notice of Change of Address: 1. Change of Address Form (Form MV-33). This form is used to update the BMV and DMV with a new address. 2. Change of Address Form for Motor Vehicle Registration (Form MV-38). This form is used to update the state of Maine with your new address for vehicle registration.
