Bring your ID and other documentation. You may also register and vote at your polling place on Election Day. You may need to wait in line so please allow extra time and bring your ID and other documentation.

Registering by mail

If you can’t register in person, you can register by mail by following these steps.

    • Print out and complete a Wyoming voter registration application.
    • Unless you’re an active member of the military or an overseas citizen, you must sign the application in front of a notary public (remember to bring photo ID or the documents listed above).
    • Send the completed and notarized form to Park County Elections, 1002 Sheridan Ave., Cody, WY 82414, along with a copy of the ID you showed the notary.

Be aware that, under federal law, voters who register by mail must present photo ID before voting for the first time. Wyoming also has a  voter ID law that requires voters to show ID when voting in person.

If you have neither a valid Wyoming driver’s license nor a Social Security number, please contact the Elections Office.

Changing/updating your registration

If you need to update your name or address, you must follow the same process as when you first registered. That means presenting your ID at the courthouse, Powell City Hall or Meeteetse Town Hall (or, if making the change by mail, to a notary).

A person can update or change their party affiliation for a primary election no later than the day before candidate filing begins. The candidate filing period begins ninety-six (96) days before the primary election. The last day to change or declare a party affiliation prior to the primary election is May 13, 2026. After the primary election but no later than 14 days before the general election voters can change their party affiliation.
