Voting Information for South Dakota

Don’t miss your next election!

The voter registration deadline for South Dakota is Oct. 19th. If you would prefer to vote by mail, you must request a ballot by Nov. 2nd at 5pm. We recommend you apply as soon as possible.

Vote-by-mail systems are different in every state. It is critical that you follow directions and pay attention to the details, or your ballot could be challenged or even tossed. 

The signature on your ballot must match your DMV signature, or signature that is on file with your voter registration if you do not have a state-issued ID. If your signature does not match, your ballot could be tossed.

Here are some important things to know about voting by mail in South Dakota:

Don't forget to put postage on your ballot. You are responsible for adding stamps.

Your state has a "received by" deadline of Tuesday, November 3rd. The post office suggests that ballots are mailed at least two weeks prior to make the "received by" deadline. Don't wait! You may also return your ballot via a delivery service, like FedEx or UPS, to ensure delivery date.

Your state does NOT offer voters a chance to address challenges to their ballot. Your ballot will be tossed if your signature does not match or you do not follow directions. Pay close attention to your state’s completed absentee ballot requirements so your vote is counted.

Your state offers electronic, barcode ballot tracking services so you can make sure your ballot gets counted. Click here to access.
