Voter Registration

Same-Day Registration: YES — for the November 3, 2026 general election, you can register in person at your county election office through the close of polls at 8:00 PM on Election Day.

Registration Deadline: By mail, postmarked no later than October 5, 2026 (30 days before Election Day; the statutory 30-day mark falls on a Sunday, so the effective deadline rolls to the following business day). After that date, registration continues in person only, during a “late registration” period running through noon on Monday, November 2, 2026, and then — separately — in person at your county election office on Election Day itself, November 3, 2026, through the close of polls at 8:00 PM. That final, Election-Day option is preserved only by a preliminary court injunction (see Notes below); confirm it hasn’t changed by checking with your county election office close to Election Day. Photo ID Required to Register: No — Montana’s registration form asks for a number, not a physical ID: your Montana driver’s license number or the last four digits of your Social Security number. Only if you have neither must you instead provide a current, valid photo ID (a school/postsecondary or tribal photo ID counts) showing your name, or a utility bill, bank statement, paycheck, government check, or other government document showing your name and current address. Accepted IDs (if you lack a driver’s license number or SSN): A current, valid photo identification — including a school district/postsecondary education photo ID or a tribal photo ID — with your name, OR a current utility bill, bank statement, paycheck, government check, or other government document showing your name and current address.

Registration Links

Notes: Election Day registration exists because a Montana district court (Judge Adam Larsen, Lewis and Clark County) preliminarily enjoined Senate Bill 490 (2025) on May 11, 2026. SB 490 would have ended same-day registration at noon and eliminated in-person registration on Election Day itself. As of September 7, 2026, that injunction stands and Election Day registration remains available through the close of polls (8:00 PM) — but it is a preliminary ruling, not a final one, so confirm current status close to Election Day. Separately, a companion 2025 law, House Bill 413, tried to bar temporarily-present college students from registering locally; it was also preliminarily enjoined in early 2026 and remains blocked as of this writing. If you don’t have your driver’s license number or SSN on hand, bring photo ID plus a current utility bill, bank statement, paycheck, government check, or other government document showing your name and current address.

Birth Certificates

A birth certificate may be needed to prove citizenship or obtain other identity documents.

Issuing Agency: Montana Department of Health and Human Services, Office of Vital Statistics Fee: $16.00 for first copy, $16.00 for additional copies Standard Processing Time: 2-4 weeks Expedited Option: Montana’s vital records office does not run its own rush service, but VitalChek (linked below) offers electronic filing plus expedited shipping for an added fee, which can return a certified copy in as little as a few business days — confirm current pricing and timing with the Office of Vital Statistics or VitalChek directly.

How to Request

  • Request Online
  • By Mail: Montana Vital Records, 111 N Sanders, P.O. Box 4210, Helena, MT 59604-4210

Notes: Records available from 1907 to present. Only authorized individuals can order certified copies including registrant (14+ years), spouse, children, parents, grandparents, caretaker relatives, guardians, or authorized representatives. Proof of relationship required. Valid government-issued photo ID with signature required for all applicants.

Proof of Citizenship Documents

You may need proof of citizenship to register to vote or to obtain a REAL ID.

Accepted Documents

  • U.S. Passport
  • Birth Certificate (for U.S.-born citizens)
  • Certificate of Naturalization
  • Certificate of Citizenship

How to Obtain Citizenship Proof

For U.S.-born citizens, obtain a certified copy of your birth certificate from the vital records office in your birth state. For naturalized citizens, contact USCIS at (800) 375-5283 or visit USCIS website to replace a lost Certificate of Naturalization using Form N-565. For those who derived citizenship, apply for Certificate of Citizenship using Form N-600.

For US Citizens Abroad

U.S. citizens abroad can apply for a U.S. passport at U.S. embassies or consulates, which serves as proof of citizenship. For replacement naturalization certificates, contact USCIS at (800) 375-5283 or submit Form N-565 by mail to the USCIS Elgin Lockbox facility.

Notes: Montana voting requires photo ID, and a U.S. Passport is accepted as valid identification for voting. The sources focus on voting ID requirements rather than comprehensive citizenship proof requirements. Birth certificates are sufficient proof for U.S.-born citizens and do not require additional certification processes.

Voting Laws & Legal Resources

Montana requires voters to present photo identification when voting in person. Accepted forms include a valid driver’s license, state ID card, military ID, tribal photo ID, U.S. passport, Montana concealed carry permit, or Montana university system/NAIA student photo ID. Voters who don’t have these options can present any other form of photo ID along with additional documentation showing their name and current address, such as a utility bill or bank statement. Montana allows same-day voter registration at polling locations and county election offices. Voters who have previously voted in Montana or registered in person typically don’t need to provide ID for absentee voting, but first-time mail voters who registered by mail may need to provide identification.

Recent Law Changes

  • 2025 (Senate Bill 276): Updated Montana’s voter-ID law and expanded the accepted-ID list to explicitly include student ID cards (Montana University System/NAIA photo ID) and tribal photo ID cards, alongside driver’s licenses, state ID cards, military IDs, U.S. passports, and concealed-carry permits. Upheld — a Montana district court left SB 276 in place in the same May 11, 2026 ruling that blocked SB 490 (below), finding no eligible voter had been denied a ballot under it.
  • Impact: Voters (including students and tribal members) have a broader set of accepted photo IDs for in-person voting.
  • 2025 (Senate Bill 490): Attempted to end same-day/Election Day registration at a hard noon cutoff the day before the election, and to eliminate in-person registration on Election Day itself. Preliminarily enjoined May 11, 2026 by a Montana district court (Judge Adam Larsen) — not a final ruling. As of September 7, 2026, Election Day registration remains available in person through the close of polls (8:00 PM).
  • Impact: Voters can currently still register and vote on Election Day itself, but this protection could change before November 3 if the litigation resolves differently — confirm close to Election Day.
  • 2021 (House Bill 176 and House Bill 530), struck down March 2024: HB 176 would have ended Election Day registration; HB 530 restricted third-party ballot-collection assistance. Both were permanently struck down by the Montana Supreme Court in Western Native Voice v. Jacobsen (March 2024) as unconstitutional burdens on Native American and young voters.
  • Impact: Election Day registration and paid or volunteer ballot-collection assistance are both currently unrestricted by either 2021 law — this is settled, not pending, litigation.

If You Are Denied the Right to Vote

Know your rights. You have the right to vote if you are eligible. If denied, do NOT leave — ask for a provisional ballot.

Denied Enroute to the Polling Place

  1. Step 1: Call Election Protection hotline at 866-OUR-VOTE (866-687-8683) immediately for assistance
  2. Step 2: If you have a felony conviction, know that Montana restores your voting rights automatically once you are no longer incarcerated for that conviction (probation/parole does not bar voting) — confirm your specific status with your county election office if unsure
  3. Step 3: Contact your county election office to confirm registration and polling location
  4. Step 4: If transportation issues persist, ask about emergency ballot options or alternative polling locations

Denied at the Polling Place

  1. Step 1: Ask for a provisional ballot – you have the right to cast one
  2. Step 2: If challenged by another voter, complete the ‘Affidavit of Challenged Elector’ form
  3. Step 3: Call 866-OUR-VOTE (866-687-8683) immediately while still at polling place
  4. Step 4: Ask poll workers to check if you can use same-day registration (allowed in Montana)
  5. Step 5: Request to speak with election judge if poll workers are unclear on procedures
  6. Step 6: Document names of poll workers and exact reasons given for denial

Provisional Ballot: In Montana, if you are challenged at the polls, you can vote a provisional ballot after completing an affidavit. Challenges must be made by a registered Montana voter in affidavit form. If you provide a current address matching your registration, you should receive a regular ballot. Montana allows same-day voter registration in most cases, so unregistered eligible voters can often register and vote on Election Day.

Native American Voter Access on Reservations

Access for Native voters on Montana’s reservations is an ongoing, live issue, not a resolved one. Distance is the core problem: county election offices and, where they exist, ballot drop boxes can be dozens of miles from a reservation community, and Montana has no statewide law requiring satellite voting sites or drop boxes on or near reservations — any that exist are set up at a county’s own discretion. This is also why third-party ballot-collection assistance matters disproportionately on reservations, and why its 2024 restoration was significant: the Montana Supreme Court’s March 2024 ruling in Western Native Voice v. Jacobsen, which struck down both House Bill 176 (ending Election Day registration) and House Bill 530 (restricting ballot-collection assistance), did so specifically on the finding that both laws placed unconstitutional burdens on Native American and young voters. Tribal nations — including the Confederated Salish and Kootenai Tribes, Blackfeet Nation, Fort Belknap Indian Community, and Northern Cheyenne Tribe — intervened as plaintiffs in that case and again in the 2026 challenge to Senate Bill 490. If you are a Native voter facing an access problem — a polling place or drop-off point that’s an unreasonable distance away, an ID or registration issue, or difficulty finding a ride — contact the Election Protection Hotline (866-687-8683) or the Native American Rights Fund, and document what happened.
