To be eligible to vote you must be:

• A United States citizen
• At least 18 years old on or before the election
• A resident of South Carolina
• Not under a court order declaring you mentally incompetent
• Not confined in any public prison resulting from a conviction of a crime

Incarcerated Voters & Returning Citizens: 

In South Carolina, you lose your right to vote if you are incarcerated after a criminal conviction (felony or misdemeanor). People who were incarcerated for misdemeanors can register to vote immediately after their release, while people who were convicted of felony offenses or election offenses must complete their sentence—including incarceration, parole, and probation—before registering to vote. Pretrial detention does not restrict your voting rights in South Carolina. 

Voters without traditional residence: 

If you do not have a street address or a permanent residence, use the map provided on your voter registration form to show where you live or spend most of your time, with landmarks and road names. If you do not receive mail at your residential address, the mailing address on their registration form can be a P.O. box, local shelter, advocacy organization, outreach center, or the home of someone who will accept mail for you.
