Where to vote
Registered at home but living somewhere else?What Missouri says to do when the address you are registered at is not the address you live at.
We have not confirmed Missouri’s rule for this from an official source yet, so we are not printing one. Check which address you are registered at, then ask that county election office what to do.

Checking. Missouri says no-excuse absentee voting in person runs from the second Tuesday before an election to the day before, at places your local election authority sets, but the state has not printed the 2026 dates on the pages we read, so we do not compute them. Ask your state election office.

What to bringThe ID Missouri accepts, and what to do if you do not have one.
ID your state accepts
- A nonexpired Missouri driver or non-driver license
- A nonexpired military ID, including a veteran’s ID card
- A nonexpired United States passport
- Another photo ID issued by the United States or the state of Missouri which is either not expired or expired after the date of the most recent general election
A Missouri driver or non-driver license that expired after the most recent general election is also acceptable.

Carry a second document
Checking. Missouri counts a provisional ballot by a later photo ID or a signature match rather than by a second document, so there may be nothing to print here. We are confirming that before we say so. Ask your state election office.

Who runs your election
The Missouri Secretary of State administers elections in Missouri. Your county or parish election office runs the polling places, counts the ballots, and answers questions about your own ballot. They are the people to call, and the ones whose answer is final.
Statewide offices are the ones every voter in Missouri votes on, and every ballot counts the same from any precinct in the state. District seats are drawn on a map, so where you live decides which of those you vote on.
Some years a ballot also asks voters to change the rules of voting itself. Those questions tend to cover:
- what counts as ID at the polls or with a mail ballot
- how early voting and mail voting work, and by when
- how districts get drawn and who draws them
- how the election office itself is run and funded
We do not tell you what is on your ballot or what to make of it. Your sample ballot carries the official wording, written by the state. Read it at the Missouri Secretary of State.
Mail, honestlyVoting by mail works. It also has rules, and the rules are where ballots get lost.
Your dates are above: when to ask for the ballot, when it has to be back, what happens if a signature is questioned.
- Sign exactly the way you signed when you registered.
- Send it back early, not on the last day.
- Would rather not trust the mail? Check the early in-person window above and go in person.
Ask for your ballot by
Checking. Missouri says mailed or faxed absentee requests must be received by 5:00 p.m. on the second Wednesday before the election, but it does not print the 2026 date on the pages we read, so we do not compute it. Mail absentee voting requires a listed reason. Ask your state election office.
It has to be back by
Checking. We have not found the Secretary of State stating when a voted absentee ballot must arrive, or whether a postmark counts, on the pages we read. Ask your state election office.
Track your ballot
Checking. We have not found the Secretary of State naming an absentee ballot tracker on the pages we read. Ask your state election office.
If your signature is questioned
Checking. We have not found the Secretary of State describing how to fix a problem with a returned absentee ballot on the pages we read. Ask your state election office.
The lineIf the line is long, that is not a reason to leave. It is a reason to stay.
Bring water. Bring a charger. Bring a chair if you can carry one, a book, and a friend. Check your bag rules with your county first. If you are in line when the polls close, stay in line: your state decides what happens next, and every state page here prints its own rule in its own words.
- Water
- A charger
- A chair if you can
- Something to read
- A friend

Time off to vote
Checking. We have not found the Missouri Secretary of State stating a time off to vote rule on a voter page, so we print nothing yet. Ask your state election office.
Your rightsA provisional ballot, help if you need it, and the number to call from the line.
You can vote a provisional ballot
If your name is not on the list, or you do not have what they ask for, ask for a provisional ballot. In a federal election you have the right to cast one. Ask what you must do afterwards for it to count, and write it down.
You can bring someone to help
You can bring a person of your choice to help you vote, with limits your state sets on who it cannot be. Ask the poll worker for the rule in writing.
Language and disability assistance
Polling places must be accessible, and many places must provide help in other languages. Ask for the accessible machine, the curbside option, or the language help you need.
If someone tries to move you off your vote
Questions about your citizenship, a crowd following you in, someone filming you at the door, a person telling you that you cannot vote: none of that decides your vote. Do not leave the line. Call the hotline from where you stand.
