Some states do not allow ordinary write-ins. Others limit them by office or election type.

Write-in & mail voting rules
Can you write in a candidate? Can you vote by mail? The answer depends on your state—and sometimes the race.
This guide covers all 50 states and Washington, D.C. It explains broad rules and important exceptions.
Find your stateA name on the ballot is not the same as a counted vote
Did the candidate qualify?
Many states require the candidate to file papers first. The person must also be eligible for the office.
Was the vote marked correctly?
Follow the ballot’s instructions. Rules about names, marks, and counting differ.
A blank line does not mean every name can win. Ask your election office whether your chosen candidate qualifies for that particular race. A total labeled “write-ins” may combine many names rather than list each person.

Three ways states handle mail ballots
Ballot sent automatically
Active registered voters receive a ballot for covered elections. In-person options remain. Vermont’s statewide system covers general elections, not every election.
Any voter can request one
You do not need a special reason, but you usually need to request the ballot.
A qualifying reason is needed
You generally need a reason allowed by state law, such as being away or having an illness or disability. Reasons vary.
An application is not a ballot. Some ongoing lists send ballots; others send application forms that you must return. Also, no-excuse voting in person does not necessarily mean no-excuse voting by mail.

Before voting, check these details
- Is this a primary, general, special, or local election?
- Is your write-in candidate qualified for this office?
- When must you request and return a mail ballot?
- Does the ballot need to arrive by a deadline, or is a postmark enough?
- What signature, ID, witness, or other instructions apply?
- Can you track the ballot or correct a problem?
A mail ballot is not always required to travel back through the mail. Use only the return methods your election office allows.
Find your official election officeA different meaning of “write-in”: the overseas backup ballot
The Federal Write-In Absentee Ballot is a backup for eligible military and overseas voters whose regular ballot may not arrive in time. Its name does not mean it creates an ordinary write-in candidacy in a state that bans one.
Mail voting did not start in 2020
States used absentee voting for soldiers during the Civil War. Later, states expanded civilian absentee voting and developed automatic-mail systems on different schedules. Hawaii’s statewide mail system began in 2020; it was not already operating statewide before that year.

The national comparison was rechecked October 18, 2026. Selected state exceptions were checked against election-office guidance and statutes. A second pass clarified Wisconsin’s registration exception, D.C.’s filing timing, and Washington’s reporting rules. This was not a new, office-by-office legal audit of every state. Original record dates remain visible in the state profiles.
Mail categories describe access to a ballot, not all rules for returning or counting it. The write-in categories describe broad patterns. Neither category guarantees that a particular candidate or ballot qualifies.
