What do I need to register my vehicle if I am coming from another town in Maine?

  • Previous registration.
  • Proof of residency in Mercer (Electric Bill, Credit Card Statement, Updated Driver's License, etc.).
  • Proof of current insurance (meaning the insurance card has to be good for the day you are registering and must show Effective and Expiration dates).  We cannot accept old insurance cards or insurance cards not yet in effect.
  • Current mileage of the vehicle you are registering.
  • If you have to file an SR-22, please be prepared and come into the Town Office before the BMV office closes because we must call them to get approval to proceed with your registration.
