Five states currently conduct all elections entirely by mail: Colorado, Hawaii, Oregon, Washington and Utah. At least 21 other states have laws that allow certain smaller elections, such as school board contests, to be conducted by mail. For these elections, all registered voters receive 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.”
While “all-mail elections” means that every registered voter receives a ballot by mail, this does not preclude in-person voting opportunities on and/or before Election Day. For example, despite the fact that all registered voters in Colorado are mailed a ballot, voters can choose to cast a ballot at an in-person vote center during the early voting period or on Election Day (or drop off, or mail, their ballot back).
Generally, states begin with providing all-mail elections only in certain circumstances, and then add additional opportunities as citizens become familiar with procedures. Oregon’s vote-by-mail timeline includes four times that the legislature acted prior to the 1998 citizens’ vote that made Oregon the first all-mail election state. See below for state-by-state statutes.

- Voter convenience and satisfaction—Citizens can vote at home and take all the time they need to study the issues. Voters often express enthusiasm for all-mail elections.
- Financial savings—Jurisdictions may save money because they no longer need to staff traditional polling places with poll workers and equip each polling place with voting machines. A 2016 study of Colorado from the Pew Charitable Trusts found that costs decreased an average of 40 percent in five election administration categories across 46 of Colorado’s 64 counties (those with available cost data). However, the study examines a number of reforms that Colorado enacted in 2013, with all-mail elections being the most significant. Others included instituting same day registration and shortening the time length for residency in the state for voting purposes.
- Turnout—Some reports indicate that because of convenience, voter turnout increases. These reports assert that turnout increases by single digits for presidential elections and more in smaller elections. See this 2013 report on all-mail ballot elections in Washington and this 2018 report on all-mail ballot elections in Utah. Effects on turnout can be more pronounced for low propensity voters, those that are registered but do not vote as frequently.
- Tradition—The civic experience of voting with neighbors at a local school, church, or other polling place no longer exists.
- Disparate effect on some populations—Mail delivery is not uniform across the nation. Native Americans on reservations may in particular have difficulty with all-mail elections. Many do not have street addresses, and their P.O. boxes may be shared. Literacy can be an issue for some voters, as well. Election materials are often written at a college level. (Literacy can be a problem for voters at traditional polling place locations too.) One way to mitigate this is to examine how voter centers are distributed throughout counties to best serve the population.
- Security—During all-mail elections (and absentee voting), coercion by family members or others might occur.
- Financial considerations—All-mail elections greatly increase printing costs for an election. Additionally, jurisdictions must have appropriate equipment to read paper ballots at a central location, and changing from electronic equipment to equipment that can scan paper ballots can be expensive.
- Slow vote counting—All-mail elections may slow down the vote counting process, especially if a state's policy is to allow ballots postmarked by Election Day to be received and counted in the days and weeks after the election.
