Marathon County Uniform Addressing

Who will Marathon County inform of my address change?

Marathon County will take care of notifying the following entities:

  • Marathon County E911 Communication Center
  • United States Postal Service
  • Municipal Officials
  • Marathon County Clerk/Elections
  • Marathon County Treasurer
  • Local Fire and Police Departments
  • Marathon County Departments

Marathon County is partnering with the U.S. Postal Service (USPS) to automatically forward any mail sent to former addresses for a period of 1 year from the property's address-activation date (that is, the date your flag-style sign is installed in the ground or the date your building-mounted sign is mailed to you).

Property owners do NOT need to file a Change of Address with the USPS.
