In all-mail elections, all registered voters are sent a ballot in the mail. The voter marks the ballot, puts it in a secrecy envelope or sleeve and then into a separate mailing envelope, signs an affidavit on the exterior of the mailing envelope and returns the package via mail or by dropping it off.

Ballots are mailed out well ahead of Election Day, and thus voters have an “election period,” not just a single day, to vote. All-mail elections can be thought of as absentee voting for everyone. This system is also referred to as “vote by mail.”

  • Eight states—California, Colorado, Hawaii, Nevada, Oregon, Utah, Vermont and Washington—allow all elections to be conducted by mail.
  • Two states—Nebraska and North Dakota—permit counties to opt into conducting elections by mail.
  • Nine states—Alaska, Arizona, Florida, Kansas, Maryland, Missouri, Montana, New Mexico and Wyoming—allow specific small elections to be conducted by mail.
  • Four states—Idaho, Minnesota, New Jersey and New Mexico—permit all-mail elections for certain small jurisdictions.

The four tables below show which states allow which types of all-mail elections.
