I've been assigned a new address or re-addressed, what should I do?

Take note of the effective date of the address change. There are a few common changes with your new address, especially if the residence is an established home and not new construction. Once the address  numbers and the road sign(s) are in place, the transition should go smoothly if you follow these guidelines:

  • Submit a Change of Address Form online with the United States Postal Service (USPS) or visit your post office to obtain a paper Change of Address form.
    • Check with the USPS to see how long they will forward mail to your new address.
    • If you are now on a newly named road, the USPS needs to build this new address/road into the USPS database. Verify with the USPS that this new road and address exist in the database before submitting a change of address.
  • If you have a land line telephone at the residence, contact your telephone provider and give them your new address. If you were to call 9-1-1 and were unable to speak, your address will automatically be displayed for the dispatcher.
  • If you use a mobile phone(s), register your mobile number(s) and your new physical address with Smart911.
  • Contact your local fire station and let them know your new address.
  • Contact your utility providers and let them know your new physical address.
  • Provide your new address to your mortgage/insurance companies and any other important financial service providers you patronize.
  • Provide your new address to any subscription providers you patronize.
  • When paying your property taxes, make note of your new physical address for the Montana Department of Revenue.
