To find the elected officials who represent you, go to https://maps.legis.wisconsin.gov/ and enter your address. A district map will come up along with names, pictures, phone, and email addresses of your Wisconsin State Senator and Assembly Representative. By clicking on “For more information click here” (it appears in tiny print at top of the box showing the state elected officials) a page will come up that identifies your Congressman and U.S. Senators.
You can also go to https://myvote.wi.gov/en-us/my-elected-officials. You will be asked to enter your address. If you are a registered voter, it will provide a comprehensive list of your elected officials, from President to your local school district.
Alternatively, free directories of Wisconsin national and state elected officials can be viewed and downloaded from these two sites:
https://www.wispolitics.com/wp-content/uploads/2022/03/220310_Directory.pdf
https://wifamilycouncil.org/election-central/contact-officials/
The two directories contain email addresses, phone numbers for Washington DC and Madison offices and sometimes for district offices, and mailing addresses for offices in Madison and Washington, DC.
