Voter Registration Applications must be postmarked by the Election Day deadline
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. To update a registration after such changes: https://www.sos.mo.gov/elections/goVoteMissouri/votereg#1_3
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: https://www.sos.mo.gov/elections/goVoteMissouri/localelectionauthority
Note: St. Louis City and St. Louis County are not the same office and they each have separate mailing addresses.
There are no ID requirements for when you register to vote in Missouri.
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.

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
