​
In-Person Voter Registration
When registering to vote in-person, you will be asked to complete the Montana Voter Registration Application. See what the form looks like here.
Blank registration forms will be provided at your in-person voter registration location. You may also print out the form yourself, fill it out at home, and drop it off at your in-person registration location.
If you are registering to vote in-person within 25 days of an election, you will likely be issued an absentee ballot at the same time as you complete your in-person voter registration. You may vote your ballot on the spot or take it home to fill out later.
​
Identification
Be prepared to provide proof of your identity when you register to vote. There are three options for this in Montana:
-
Option 1: Provide a Montana Driver's License number or Montana ID number.
-
Option 2: Provide the last 4 digits of your Social Security number.
-
Option 3: Provide a copy of another form of identification. This can be a photo ID that shows your name or an acceptable ID that shows your name and current address (Tribal ID, a recent paycheck stub, utility bill, or bank statement, your student ID, or another government document addressed to you).
