South Carolina vote by mail directions

In almost all cases, you will need to sign up to vote by mail. The state won’t just mail you a ballot. Don't worry: we will walk you through it. There are only a handful of steps:

  1. You submit an application to vote by mail
  2. Your Local Election Office processes your application
  3. Your Local Election Office sends your ballot to you
  4. You vote using the ballot and return it by the deadline

Apply to vote by mail

  1. Visit the South Carolina vote by mail website.
  2. Fill out all of the required fields.
  3. Print the form.
  4. Sign and date your form. This is very important.
  5. Mail or hand-deliver your completed form directly to your Local Election Office as soon as possible, but no later than the deadline.
  6. If it’s close to the deadline, call your Local Election Office and see if they will let you submit your form via email or fax.

How to vote by mail

  1. Carefully read and follow the instructions.
  2. Fill out all of the required fields.
  3. Sign and date the outside envelope.
  4. Mail or hand-deliver your ballot to your Local Election Office.
  5. Your ballot must be received by the deadline or it will not be counted.

Two important things to note:

  1. The Local Election Office will compare your signature on your voted ballot to the one on your driver’s license and on your voter registration form to make sure they match. So please sign carefully.
  2. The post office will deliver your ballot even if you don’t have a stamp as long as you use the return envelope provided by your state. This envelope will say “official election mail.” The USPS will always deliver official election mail -- no stamp needed.
