To cancel your plate, you need your email address, the type and number of the plate, the last four digits of your Social Security Number, and a Driver’s License. Once you have finished cancelling your MA plates, please inform our office and send us a copy of the Plate Return Receipt for proof that coverage for the vehicle has been cancelled. As a courtesy to our customers, we offer various RMV services such as Registration and Title Applications, plate transfers, registration renewals etc.
