Identification Requirements

Identification Requirements to Cast a Ballot

Valid forms of ID are:

  • Identification issued by the state of Missouri, an agency of the state, or a local election authority of the state (such as a driver’s or non-driver’s license, or voter notification card sent by the Election Authority);
  • Identification issued by the United States government or agency thereof (such as a Passport or Military ID);
  • Student identification issued by an institution of higher education, including a university, college, vocational and technical school, located within the state of Missouri; or
  • A copy of a current utility bill, bank statement, paycheck, government check or other government document that contains the name and current address of the voter (including the voter notification card the voter received in the mail from the election authority).

Voters who do not have one of these forms of ID but are registered can cast a provisional ballot but that provisional ballot will be counted only if the voter returns to their polling place before close of polls on Election Day with valid photo ID, or if the signature on the provisional ballot is found to match the signature on their voter registration record. See List of Acceptable ID’s here

If You Have Moved Within Your State

Moved within the Same County

Voters who are registered should go to the polling place serving his or her new address. Voters must be permitted to file a change of address at the polls on Election Day.  The voter may also file a change of address and vote at the central polling location, such as Election Board Headquarters or clerk’s office.

Moved To a New County

A registered voter who has changed his or her county of residence must register to vote again in the new county of residence.  If the voter moved after the registration deadline and otherwise possesses the qualifications to vote, he/she may vote by absentee ballot for all statewide and nationwide candidates and questions. NOTE: St. Louis City is a different election jurisdiction from St. Louis County. Similarly, Kansas City is a separate election jurisdiction than the rest of Jackson County, so voters who have moved between St. Louis City and St. Louis County would have to register anew, as would voters who move from Kansas City to elsewhere in Jackson County.

If You Are a Military or Overseas Voter

Military and other overseas citizens may use the standard procedure for absentee voting by mail, but there are also special provisions for members of the U.S. Armed Forces and merchant marine, commissioned corps of the Public Health Service and National Oceanic and Atmospheric Administration, along with family members of all these groups, and other citizens who reside outside the United States (together these groups are called UOCAVA voters). Absentee ballots cast by military or overseas voters do NOT need to be notarized. 

The Missouri Military and Overseas Voting Access Portal is a secure website allowing voters to 1) register to vote, 2) request and receive your absentee ballot, and 3) if you are a military member in a hostile zone transmit your marked ballot. It is available to: 

  • Missouri voters that are part of the United States Uniformed Services, National Guard, Federal Service, their spouse or dependent; any active military member, whether stationed in the United States or overseas can use the Military and Overseas Voting Access Portal.
  • Missouri voter currently overseas

Registering and Requesting an Absentee Ballot

Military and overseas voters can check whether they are registered using the voter registration look up tool. If they are not registered to vote, they can register and request an absentee ballot at the same time by:

  1. Accessing the Military and Overseas Voting Access Portal;
  2. Registering to vote through Missouri’s secure website; or
  3. Completing a Federal Post Card Application and mail it to your local election authority.

Missed the deadline? Voters who miss the voter registration deadline can register under provisions of state and federal law that allow members of the armed forces and their dependents to vote in federal races only. 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 an Absentee 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. A voter can request your absentee ballot by:

  1. Accessing the Military and Overseas Voting Access Portal or
  2. Completing a Federal Post Card Application and mailing it to your local election authority via U.S. Mail, commercial carrier, or by hand delivery.

Federal Write-In Absentee Ballot

The Federal Write-in Absentee Ballot (FWAB) is a back-up ballot that can be used by UOCAVA voters.  You can use this FWAB whether you are located inside or outside the United States (including APO and FPO addresses), provided that you are away from your voting residence for service-related activities.  You must apply for a regular ballot early enough for your local election officials to receive the FEAB request at least 4 days before the Election Day.  If you do not receive your regular ballot in time, you may use the FWAB.  Your FWAB must be received by your local voting officials in Missouri by the 28th day before Election Day if used for registration, or otherwise received by the 3rd day after Election Day.  For specific instructions, visit the FVAP’s Missouri-specific FWAB page.  

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:

  1. MAIL – Most voters are required to return their ballot and accompanying absentee affidavit by mail; postage is not required if you are mailing your ballot from an APO/FPO mail facility, U.S. embassy or consulate, or U.S. post office.  You must use the prepaid return envelope template to receive free postage.
  2. MAIL, FAX, EMAIL or through the Military and Overseas Voting Access Portal (beginning with the November 2014 General Election) – If you are serving in a hostile zone   such as Iraq, Afghanistan, or Kosovo, you may return your voted ballot and accompanying absentee affidavit using one of these methods.

Absentee ballots must be received by your local election authority no later than 12:00 p.m. CST on the Friday following the election.

Tracking Your Ballot

Track your ballot online using Missouri’s Military and Overseas Voting Access Portal. If you mail, fax or email your ballot, you can confirm that your ballot was received by your local election authority by contacting our office at [email protected] or (866) 868-3245.

If You Have a Felony Conviction

In Missouri, a person is ineligible to vote: (1) while under a sentence of imprisonment, (2) upon conviction of a felony (or a misdemeanor related to voting); or (3) while they are under state supervision for conviction of a felony. Those convicted of a felony become eligible to vote once discharged from probation or parole (also known as being “off paper.”). A person convicted of a felony automatically regains eligibility to vote after such person has fully completed his/her sentence, including probation or parole, but must re-register.  

People who are in jail on pretrial detention or awaiting trial – as well as anyone who has not been convicted – retain the right to vote. They have a right to vote absentee.

A person convicted of a crime (felony or misdemeanor) related to voting is ineligible to vote again unless such person is pardoned by the governor and, after such pardon, the election authority determines that such person is eligible to vote.

If You Need Assistance

Any voter who needs assistance voting due to disability, blindness, or inability to read or write (including limited English proficiency) is entitled to have a person of their choice (except their employer or union representative) assist them in reading the ballot or marking the voter’s choices or otherwise assist the voter in marking their choices on the ballot. The chosen assistant does not need to be 18 years old, a U.S. citizen or a registered voter. Alternatively, the voter may seek assistance from a bipartisan team of poll workers.

Voters who have disabilities or for other reasons believe they can not enter the polling place or wait in lines inside the polling place also have the right to vote “curbside” from their car.  For any voter within 200 feet of a polling location who believes they would be unsafe or unable to enter the location or wait in line, two election judges (one from each party) must take the ballot to the voter in the car. Voters do not need to present any paperwork or divulge their medical information to avail themselves of curbside voting.  A voter who believes she needs this assistance is entitled to it.

Persons with permanent disabilities or who are homebound can request to be placed on a designated list to automatically be mailed an absentee ballot application prior to each election. Persons who were hospitalized after the absentee application request deadline can request a team of election officials to bring the ballot to the hospital on or before Election Day.
