Acceptable documents include a recent utility bill, bank statement, paycheck, residential lease, or any government document that shows your name and address.
Contact your Local Election Office if you have questions.
This is the statewide agency that is ultimately responsible for Montana elections. You can contact them with questions, but your Local Election Office will probably respond faster.
