Sharing the Facts About Mail Voting

Issue Areas

Millions of Americans—across rural areas, suburbs, and cities—cast their ballots by mail. Mail voting provides a safe, secure, and accessible alternative to going to a polling place in person to vote, and is a practice spanning more than 160 years, dating back to soldiers voting during the Civil War.

Americans of all backgrounds utilize this method of voting; nearly one-third of voters in 2024 cast their ballots by mail, according to research from States United.

While all states allow mail voting, specific procedures vary and are set by states. In more than half of the states, voters may request a mail ballot without providing a reason for doing so.

States have also made different decisions about whether to count ballots that are sent by Election Day but arrive shortly after. In June 2026, the U.S. Supreme Court held that federal law does not dictate when a ballot must be received in order for it to count. States can determine for themselves the deadlines for when mail ballots can be received, as long as they are mailed before or on Election Day. Voters should make a plan to vote, understand their state’s deadlines, mail their ballots early, and consider using secure ballot drop boxes as needed to ensure their votes are counted.

Despite efforts by some to cast doubt on the system, states have implemented tested methods to ensure that mail voting remains secure and reliable.

Here are some key takeaways about the security of voting by mail:

    • Learn your state’s deadline for sending in a mail ballot.
