How to Vote!

Look up your Voter Registration

Here’s how to register to vote:

First, confirm whether you are or are not registered by visiting the voter information portal at the SDSOS website.

Then, fill out a voter registration form available here, at the top of the page, or on the SDSOS website.

Once filled out, you’ll need to submit the form to your County Auditor. An important note: South Dakota law does not allow you to submit your voter registration form via fax or email.

Here’s where to find your polling place:

Use the link on the top of the page labelled “Look up your Voter Registration”, or visit the SDSOS website.

There are a couple ways to absentee vote.

Absentee voting is a great way to cast your vote while being able to take time to research the candidates, and without worrying about long lines at the polls on Tuesday.

Fill out this form available above or at the SDSOS website, and return to your county auditor if you’d like to cast an Absentee Ballot instead of voting on election day. A reminder, South Dakota election law does not allow for fax or email submission of the form. You have until 5pm the day before the election to request a ballot, but it is recommended to not wait until the last minute.

Once you fill out this form, your County Auditor will mail you your ballot and you can mail it back or turn it in to your county auditor with enough time for the Auditor to hand the ballot off to the appropriate polling location (so don’t wait until the last minute!).

You can also go to your County Building and absentee vote in-person. Here’s the SDSOS’s list of County Auditor contact information for your reference.

The SDSOS has a portal for military members and overseas citizens to use to register to vote and request an absentee ballot.

1. Photo ID is a requirement to vote. You must present one of the allowable photo ID’s

  • SD Driver’s License or State Issued non-Driver’s License ID
  • U.S. Government Photo ID (passport is acceptable)
  • U.S. Armed Forces ID
  • Tribal Photo ID
  • Current student photo identification card from a South Dakota high school or South Dakota accredited institution of higher education.

2. If you don’t have an acceptable ID, you must be given the option to sign a personal affidavit that you will sign under the penalty of perjury in which you state you are the person you have declared. You then may vote using a regular ballot.

3. If at the polls, you feel that you were incorrectly prevented
from voting, you may call the County Auditor or the Secretary
of State at 888-703-5328 or your County State’s Attorney. Be
sure to make that phone call before leaving the polling place.

4. Polls are open from 7am to 7pm local time. If you are in line before 7pm local time, once in line, you will have the opportunity to cast a ballot-even if the polls have closed.
