With absentee voting — otherwise known as vote-by-mail (VBM) — you’ll receive your ballot in the mail, fill it out, and then mail it back to your state or local elections officials, rather than going to a polling place to vote.
In some states, you need a valid excuse — such as being out of town on Election Day, being physically unable to go to the polls, or being stationed overseas in the military — in order to be able to vote absentee. Other states let you vote by mail without an excuse, or mail a ballot to all registered voters by default.
To review your state’s VBM/absentee rules or apply for a mail/absentee ballot, use this online form from the Voter Participation Center.
