Voter Registration

Same-Day Registration: NO — you must register before Election Day. There is no registration at the polls in South Dakota.

Registration Deadline: Monday, October 19, 2026. Your completed form, with an original signature, must be received by your county auditor by that date — 15 days before Election Day. A postmark does not count, and South Dakota law does not allow registration forms to be submitted by fax or email.

Photo ID Required to Register: Not for identity — but **new registrants must provide documentary proof of U.S. citizenship**, and the easiest way to do that is to show a qualifying ID card in person. See Proof of Citizenship Documents — this is the most consequential change to South Dakota registration in decades, and getting it wrong costs you every state and local race on your ballot.

Where to register:

  • Your county auditor’s office — the only place you can show an ID card in person for citizenship proof
  • A driver’s license station, when you apply for or renew a license
  • A city finance office
  • Public assistance agencies providing SNAP, TANF, or WIC
  • Department of Human Services offices serving people with disabilities
  • Military recruitment offices

Registration Links

To register you must: be a U.S. citizen and be able to document it if you are a new registrant; reside in South Dakota at a physical address; be at least 18 on or before Election Day; not be serving a sentence for a felony conviction; and not have been judged mentally incompetent by a court.

Notes: Your registration address must describe a physical place you live. If you register using a commercial mail receiving agency, a mail-forwarding service, or a post office box without describing the location of your habitation in the relevant field, you will be designated a federal-only voter — the same restricted status as a missing citizenship document. Voter registration information may also be checked against the federal Systematic Alien Verification for Entitlements (SAVE) database. Under a 2026 law, any voter in your county may formally challenge your registration on a claim of suspected non-citizenship; if you receive a notice, respond to your county auditor immediately.

Birth Certificates

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

Issuing Agency: South Dakota Department of Health, Vital Records, 221 West Capitol Avenue, Pierre, SD 57501 Fee: $15 per copy, charged whether or not the record is found Fee waiver: South Dakota has a Homeless Birth Certificate Fee Waiver — if you are experiencing homelessness you can obtain a birth certificate at no cost. Ask Vital Records or a service provider about the waiver form. How to order: In person, by mail, over the phone, or online Standard Processing Time: About 2 to 3 weeks by standard mail Expedited Option: Available on online and phone orders for an additional expedite fee

How to Request

Notes: Birth records are available from 1905 to the present. South Dakota vital records are not open to public inspection — certified copies are available only to the person named on the record, a spouse, child, parent, guardian, next of kin, or an authorized representative, and you must present proof of your identity. If you were born outside South Dakota, contact the vital records office in your birth state.

Proof of Citizenship Documents

South Dakota now requires documentary proof of U.S. citizenship to register to vote. Senate Bill 175 was signed by Gov. Larry Rhoden and took effect March 26, 2026. November 3, 2026 is its first general election.

**What happens if you do not provide it: you are still registered, but only as a “federal-only” voter.** You are not turned away and you are not removed from the rolls. You are placed on a restricted roll and given a restricted ballot.

**On November 3, 2026, a South Dakota federal-only voter can vote for U.S. Senate and the U.S. House — and nothing else.** No governor. No lieutenant governor, attorney general, or secretary of state. No state legislature. No county commission, school board, or city office. No statewide or local ballot measures. Roughly **1,500 South Dakotans were already in this category ahead of the June 2026 primary**, and the number has been growing.

There is no cure process and no appeal. If your registration was accepted as federal-only because of a documentation problem, the state does not let you fix that registration. **You must submit an entirely new voter registration application, with acceptable documents, and it must reach your county auditor by Monday, October 19, 2026.** Do not wait.

The notice the state sends is known to be inaccurate. A federal lawsuit filed on August 24, 2026 — League of Women Voters of South Dakota v. Johnson, brought by the League and an individual voter with the ACLU Voting Rights Project, the ACLU of South Dakota, and the Campaign Legal Center — alleges that the letter sent to federal-only registrants does not mention proof of citizenship at all, and instead states that they were made a federal voter because they listed a nonresidential address. **If you received a letter saying you are a federal voter, do not assume the stated reason is the real one.** Call your county auditor and ask specifically whether your citizenship documentation was accepted. The suit was pending as of September 7, 2026; do not wait for it to be decided.

Check your status now. The Voter Information Portal and your county auditor can tell you whether you are on the full ballot or the federal-only ballot. If you registered for the first time in 2026, check.

Accepted Documents

Must be shown to the county auditor in person — a photocopy is NOT accepted:

  • South Dakota driver’s license or nondriver identification card issued after July 1, 2025 (these indicate citizenship status)
  • Driver’s license or nondriver ID card from another state or territory indicating citizenship has been verified
  • Tribal identification card

A legible photocopy IS accepted, and may be mailed with your registration form:

  • Birth certificate
  • U.S. passport
  • Consular Report of Birth Abroad issued by the U.S. Department of State
  • Certificate of naturalization
  • Other documentation permitted under 42 C.F.R. § 436.407 (see the Secretary of State’s

full document list)

This distinction is the single most common way a South Dakota registration fails. If your only citizenship document is a driver’s license, state ID, or tribal ID, **mailing a photocopy will not work** — you must take the card to your county auditor’s office. If you cannot get there, mail a photocopy of a birth certificate, passport, or naturalization certificate instead.

Already-registered voters do not need to provide proof unless they re-register, or are flagged and removed from the rolls.

How to Obtain Citizenship Proof

For a birth certificate, contact the vital records office in the state where you were born (in South Dakota, see the section above — and ask about the homeless fee waiver if it applies). For a U.S. passport, apply through the U.S. Department of State with your birth certificate or naturalization certificate, a government-issued photo ID, a completed DS-11, and a passport photo. Certificates of naturalization are issued on completing naturalization through USCIS; replacements use Form N-565. For a certificate of citizenship, apply to USCIS with Form N-600 if you became a citizen through a parent.

For US Citizens Abroad

U.S. citizens abroad can apply for passports at U.S. consulates or embassies, which serve as proof of citizenship. Contact the nearest U.S. consular office for requirements. Military and overseas voters should register and request ballots through FVAP and the Secretary of State’s military and overseas citizen pages — they are the only South Dakota voters permitted to submit applications by fax or email.

Notes: Tribal identification cards are accepted both as citizenship proof at registration and as photo ID at the polls, but the tribal ID must be shown in person for the registration requirement.

How to Vote

Voting in Person

Photo ID Required: Yes — but a voter without one may sign an affidavit and still vote a regular ballot. Accepted IDs:

  • South Dakota driver’s license or nondriver ID card
  • U.S. government photo ID (a U.S. passport is acceptable)
  • U.S. Armed Forces ID
  • Current student photo ID from a South Dakota high school or a South Dakota accredited institution of higher education
  • Tribal photo ID

If you have no photo ID: You must be offered a personal identification affidavit. Sign it and you vote a regular ballot, counted like any other. This is not a provisional ballot and there is nothing to cure afterward. If a poll worker does not offer it, ask for it by name and call 866-OUR-VOTE. Polls Open: 7:00 a.m. to 7:00 p.m. local time. South Dakota spans two time zones — most of the state east of the Missouri River is Central, most of the west is Mountain — so confirm your own precinct’s hours. Find Your Polling Place

Step-by-Step Guide:

  1. Step 1: Confirm your polling place and your ballot type at vip.sdsos.gov
  2. Step 2: Bring a valid photo ID to your assigned polling place
  3. Step 3: Check in with poll workers and show your ID, or ask for the personal identification affidavit if you have none
  4. Step 4: Receive your ballot and mark it
  5. Step 5: Return the completed ballot to the poll workers or the tabulator

Voting by Mail

Mail voting is available — no excuse required. In South Dakota this is called absentee voting. Application Deadline: 5:00 p.m. on Monday, November 2, 2026 for an application delivered in person to your county auditor. A mailed application must actually arrive in time for the auditor to send you a ballot and get it back — the Secretary of State recommends applying at least 7 days ahead, and two to three weeks is safer. Ballot Return Deadline: **RECEIVED by your county auditor on Election Day, Tuesday, November 3, 2026, with enough time left for the auditor to deliver it to your precinct before the polls close at 7:00 p.m. local time. South Dakota does not** count a ballot that arrives after Election Day, no matter what the postmark says. Do not mail it in the final week. Absentee Ballot Application (PDF) Absentee Voting Information

Your return envelope needs ID. South Dakota requires the absentee return envelope to carry either a photocopy of your photo identification or a notarized signature. Leaving both off is a common reason ballots are rejected — and South Dakota gives you no way to fix it afterward.

Drop boxes: there are none. South Dakota banned ballot drop boxes in 2023. Your only return options are U.S. mail or hand-delivery to your county auditor’s office. Hand delivery bypasses the postal system entirely and is the most reliable option late in the window.

If you are confined by sickness or disability, you may apply in writing for a ballot delivered by an authorized messenger, who brings the ballot to you and returns your marked ballot to the county auditor. That application must be received by the auditor **before 3:00 p.m. on Election Day**.

Step-by-Step Guide:

  1. Step 1: Confirm you are registered at vip.sdsos.gov
  2. Step 2: Print the absentee ballot application, sign it, and mail or deliver the original to your county auditor — no fax or email except for military and overseas voters
  3. Step 3: Apply by early-to-mid October; the hard cutoff is 5:00 p.m. Monday, November 2, 2026
  4. Step 4: Mark your ballot when it arrives
  5. Step 5: Attach a photocopy of your photo ID to the return envelope, or have your signature notarized
  6. Step 6: Mail it back at least two weeks out, or hand-deliver it to your county auditor’s office — it must be in the auditor’s hands on Election Day before the polls close

Voting by Absentee Ballot

Excuse Required: No Application Deadline: 5:00 p.m. on Monday, November 2, 2026 Ballot Return Deadline: Received by your county auditor on Tuesday, November 3, 2026, in time to reach your precinct before polls close at 7:00 p.m. local time Absentee Ballot Application (PDF)

Step-by-Step Guide:

  1. Step 1: Submit the signed original absentee ballot application to your county auditor
  2. Step 2: Complete the ballot when it arrives
  3. Step 3: Include a photocopy of your photo ID with the return envelope, or have your signature notarized
  4. Step 4: Return it so the auditor has it before the polls close on November 3, 2026

Early Voting

Early voting is available — South Dakota calls it in-person absentee voting, and it takes place at your county auditor’s office. Dates: Friday, September 18, 2026 through Monday, November 2, 2026 — 46 days, ending the day before Election Day. These are the dates the Secretary of State publishes for the November 3, 2026 general election. Bring photo ID — or sign the personal identification affidavit and vote a regular ballot. Satellite sites: For 2026 the state funded satellite in-person voting sites in **Lyman, Oglala Lakota, and Todd counties**, covering much of the Lower Brule, Pine Ridge, and Rosebud reservations, to cut travel distances. Ask your county auditor whether a satellite site is operating near you and what its hours are. Find Your County Auditor

Step-by-Step Guide:

  1. Step 1: Visit your county auditor’s office any weekday between September 18 and November 2, 2026
  2. Step 2: Show a valid photo ID, or sign the personal identification affidavit
  3. Step 3: Complete your ballot on the spot
  4. Step 4: Hand the completed ballot back at the counter

Voting Laws & Legal Resources

South Dakota requires voters to present photo identification at the polls. Acceptable forms are a South Dakota driver’s license or nondriver ID card, a U.S. government photo ID (including a passport), a U.S. Armed Forces ID, a current student photo ID from a South Dakota high school or accredited institution of higher education, and a tribal photo ID. A voter without photo ID may sign a personal identification affidavit under penalty of perjury and receive a regular ballot. For absentee voting, the return envelope must carry a photocopy of the voter’s photo ID or a notarized signature. South Dakota has no Election Day registration — the deadline is 15 days out — and no ballot drop boxes. In-person absentee voting at the county auditor’s office begins 46 days before Election Day. Since March 26, 2026, first-time registrants must produce documentary proof of U.S. citizenship or be limited to a federal-only ballot covering U.S. Senate and U.S. House races only.

Recent Law Changes

  • 2026 — Senate Bill 175, effective March 26, 2026: Requires documentary proof of U.S.

citizenship from anyone registering to vote in South Dakota for the first time, plus a physical South Dakota residence address.

  • Impact: Registrants who do not provide it are placed on a federal-only roll and

cannot vote for governor, the legislature, county or city offices, or ballot measures. About 1,500 voters were in this category before the June 2026 primary. There is no cure — an affected voter must file a brand new registration application. A federal lawsuit filed August 24, 2026 alleges the state’s notices to affected voters misstate the reason and offer no path to fix it; it was pending as of September 7, 2026.

  • 2026 — voter registration challenges: Any voter may challenge another voter’s

registration in the same county on a claim of suspected non-citizenship.

  • Impact: A challenged voter must respond to the county auditor within the statutory

window or risk cancellation. Do not ignore a notice.

  • 2026 — election consolidation: Municipal and school elections must be held on either

the June primary or the November general election date.

  • Impact: Fewer stand-alone local election days. Check with your municipality for timing.
  • 2026 — ballot chain of custody and presidential electors: Strengthened chain-of-custody

requirements for ballots and a prohibition on faithless presidential electors.

  • Impact: Administrative; no change to how an individual votes.
  • 2023 — House Bill 1165: Banned ballot drop boxes and tightened absentee procedures.
  • Impact: Absentee ballots must be mailed or hand-delivered to the county auditor. There

is nowhere else to drop a ballot in South Dakota.

Voting Rights Law Firms and Legal Organizations

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 the personal identification affidavit or a provisional ballot.

Denied Enroute to the Polling Place

  1. Step 1: Call 866-OUR-VOTE (866-687-8683) for immediate assistance
  2. Step 2: Document what happened — take notes or photos if it is safe to do so
  3. Step 3: Contact your county auditor or the South Dakota Secretary of State at 605-773-3537
  4. Step 4: If transportation is the problem, ask your county auditor or Four Directions about rides and satellite voting sites

  • SD Secretary of State 605-773-3537 — State election authority

Denied at the Polling Place

  1. Step 1: If you have no photo ID, ask for the personal identification affidavit — signing it gets you a regular ballot, not a provisional one
  2. Step 2: If you are told you are not registered, or your ballot is restricted, ask a provisional ballot and complete the required affirmation
  3. Step 3: If you are challenged on residency or registration, present whatever evidence of eligibility you have
  4. Step 4: Call 866-OUR-VOTE while you are still at the polls
  5. Step 5: Get the names of the poll workers involved and write down exactly what you were told

Provisional Ballot: In South Dakota you may cast a provisional ballot if you are told you are not authorized to vote, if you are successfully challenged, or if you are otherwise denied a regular ballot but maintain that you are registered in that precinct. You must complete an affirmation with the provisional ballot. **Note that a missing photo ID is not a reason for a provisional ballot in South Dakota** — the personal identification affidavit gets you a regular ballot, and you should insist on it.

Given a Federal-Only Ballot

  1. Step 1: A federal-only ballot in 2026 carries only the U.S. Senate and U.S. House races. If your ballot is missing the governor’s race, that is what has happened
  2. Step 2: Call your county auditor and ask specifically whether your proof of citizenship was accepted — the state’s notice letters have been alleged in federal court to misstate the reason
  3. Step 3: There is no cure and no appeal. To vote a full ballot you must submit a brand new voter registration application with acceptable citizenship documents, received by your county auditor by Monday, October 19, 2026
  4. Step 4: If your only citizenship document is a driver’s license, state ID, or tribal ID, take the card to the auditor’s office in person — a photocopy is not accepted for those
  5. Step 5: Call 866-OUR-VOTE or the ACLU of South Dakota if you are told there is nothing you can do

Mail Ballot Denied or Not Received

  1. Step 1: Contact your county auditor immediately — they can confirm whether your application arrived and when the ballot was mailed
  2. Step 2: If time is short, ask to vote in person instead — at the auditor’s office through November 2, or at your polling place on November 3
  3. Step 3: Call the South Dakota Secretary of State at 605-773-3537
  4. Step 4: Document the denial and request a written explanation

  • Election Protection Hotline 866-687-8683 — Voting rights assistance

Absentee Ballot Denied

  1. Step 1: Contact your county auditor to find out exactly why — the most common causes are a missing ID photocopy or missing notarization on the return envelope, or an application sent by fax or email when you are not a military or overseas voter
  2. Step 2: Fix it and re-apply before 5:00 p.m. on Monday, November 2, 2026
  3. Step 3: Call the South Dakota Secretary of State at 605-773-3537
  4. Step 4: Plan to vote in person as a backup — at the auditor’s office through November 2, or at your polling place on November 3
