Missouri law does not require an individual to register by political party.
If a voter chooses to participate in the August Primary in even-numbered years, the voter will be asked by the Election Judges which party ballot the voter wishes to vote. No record is kept of the voter's selection by the County Clerk's Office.
Missouri law requires that a voter cast a ballot based on one’s current address and current name. Update voter registration.
If you move to a different county or state, you must re-register with your new county and/or state to vote. Notify the county clerk in the Missouri county where you registered to vote if you move out of state.
Note: St. Louis City and St. Louis County are not the same office and they each have separate mailing addresses.
Effective June 1, 2017, the following forms of identification are acceptable for voting purposes in Missouri:
If you do not possess any of these forms of identification, but are a registered voter, you may still cast a provisional ballot. Your provisional ballot will be counted if you return to the polling place and show an Option 1 ID or if the signature on the provisional ballot envelope matches the signature on your voter registration record.
Registered Missourians who expect to be prevented from going to their polling place on Election Day may vote absentee beginning six weeks prior to an election. Note: Missouri distinguishes between “absentee” ballots (which require an excuse and can be dropped off in person) and “mail-in” ballots (which do not require an excuse but must be mailed back). All mail-in ballots must be notarized, and the notary service must be provided for free.
Absentee voters must provide one of the following reasons for voting absentee:
Voters can request absentee ballots from their local election authority in person, by mail, by fax or by e-mail. Relatives within the second degree (spouse, parents and children) may complete an absentee ballot application, in person, on behalf of the voter who wishes to vote absentee. Absentee ballots may be requested in person up until the day before Election Day.
Mail in or faxed absentee ballot requests must be received by the election authority no later than the 5:00 p.m. on the second Wednesday prior to any election. Voters can vote by absentee in the office of the local election authority until 5:00 p.m. the night before the election.
Voters requesting an absentee ballot by mail who have registered by mail and have not voted in person are required to submit a copy of their personal identification unless they provided a copy with their registration application.
Absentee ballot---Limited Covid-19 exceptions:
Only registered voters who are in “an at-risk category for contracting or transmitting” COVID-19 or voters who have contracted COVID-19 can select the new Covid-19 exception option that allows them to vote via absentee ballot and without a notary:
Individuals considered “at-risk” include people who:
Are age 65 or older;
Live in long-term care facilities;
Have chronic lung disease or moderate to severe asthma;
Have serious heart conditions;
Have chronic kidney disease that requires dialysis treatments;
Have liver disease.
You’re eligible to vote by mail-in if you are a registered voter. The mail-in process:
Fill out mail-in ballot application.
Deliver to election authority by mail or in-person.
Receive and fill out mail-in ballot. Have envelope notarized.
Return to election authority through U.S. mail in time for its receipt by Election Day at 7 p.m.
Request a mail-in ballot from your local election authority.
Mail-in ballots may be requested in person.
Oct. 21 at 5 p.m. is the deadline to request a mail-in ballot by mail for the Nov. 3 election.
Unlike absentee ballots, mail-in ballots MUST BE mailed back through U.S. mail.
Mail-in ballots must be returned by mail in the provided envelope, with the statement on the envelope signed and witnessed by a notary. In order to be counted, mail-in ballots must be received by the election authority at or before the time fixed by law for the closing of the polls on Election Day (7:00 p.m.).

Even if you miss the registration deadline, state and federal law allow active members of the armed forces and their dependents to vote for federal offices only. You can access a ballot at the Military and Overseas Voting Access Portal or fill out the Federal Write-In Absentee Ballot (FWAB) and mail it to your local election authority.
Requesting a ballot
Absentee ballots are available 46 days before an election. Relatives within the second degree may complete an absentee ballot application, in person at the office of your local election authority, for the eligible voter wishing to vote absentee. You can request your absentee ballot by:
Returning your ballot
You can view your absentee ballot through Missouri’s Military and Overseas Voting Access Portal. Voters using the Federal Post Card Application mark their method of receiving their ballot on the application. You can return your ballot by:
Military and Overseas Absentee ballots must be received by your local election authority no later than 12:00 p.m. CST on the Friday following the election.
Polling location information is provided and updated by local election authorities. It is recommended you confirm your polling place with your county clerk or board of election. Contact information for your local election authority.
Polling places open at 6:00 a.m. and remain open until 7:00 p.m. Those individuals arriving after the polling place has closed will not be allowed to vote. However, those individuals in line at 7:00 p.m. will be allowed to vote.
Many organizations offer free rides to polling places. Some of these include:
Curbside Voting: Voters with limited mobility can vote "curbside" or outside the polling place. Just go to your polling place and ask someone to go in and ask poll workers to bring a ballot out to you. They should bring you a ballot within a reasonable period of time.
Accessible Polling Places: If you have physical disabilities, and your polling place is not accessible, you may request a different polling place assignment so that you may vote in a more accessible polling place. You may also vote at a central location. Simply contact your local election authority to make this request. You can find your local election authority here or by calling (800) NOW-VOTE.
Accessible Voting Systems: Every polling place must have an accessible voting system for individuals with disabilities including audiovisual accessibility. Accessible systems include an audio ballot to make your selections or the ability to enlarge text so that you can read the on-screen ballot with ease.
Permanent Absentee Voting: If you have a permanent physical disability, you may request to be placed on a designated list so that your local election authority can automatically mail an absentee ballot application directly to you prior to each election. You will need to make this request directly to your local election authority who will send you further information.
You may be able to view your sample ballot at the Secretary of State’s Voter Information Lookup
Sample ballots can also be viewed at the polling place or at the office of your local election authority. Sample ballots are also required to be printed twice prior to each election in newspapers of general circulation. Some election jurisdictions may also mail sample ballots to all registered voters in that jurisdiction.
In Missouri, voters do not register with a political party. Individuals voting in the Primary Election may select a party ballot of their choice (Section 115.121.2, RSMo.). Voters who do not wish to select a party ballot in a primary may request a ballot containing other issues, if their jurisdiction’s ballot contains issues.
The 5 established political parties in Missouri are: Republican, Democratic, Libertarian, Constitution, and Green.
