How Vote By Mail Works in South Dakota

Voting by mail is a two step process in South Dakota.

Step 1: Request your ballot NOW. The deadline for your application to be received is November 7th at 5:00 p.m. - but you must request well before that to allow for time to mail.

  • Include a copy of a valid photo ID or a notarized oath with your application.

Step 2: Complete and return your ballot ASAP.

  • Return in person to your local election office by November 8th at 12:00 p.m.
  • Or stamp and mail your ballot so that it is received by November 8th at 12:00 p.m. noon. We recommend mailing your ballot at least two weeks before as the post office is not always reliable. The best intentions or postmark will not matter if your ballot is received after November 8th - your ballot will not count.

In South Dakota, you can preregister to vote if you are 18 by the next election. Register to vote today!

Some states even let you vote in their primaries at 17 if you’ll be 18 by the general election so you can participate in the whole process!
