Iowa Voting Guide

ID Requirements for Registration

Iowa requires voters to provide an identification number when registering to vote. Whether you’re registering in person, online, or by mail, you must provide one of the following:

• Iowa driver’s license number
• Iowa non-operator ID number
• Last four digits of your Social Security number (SSN)

If you have an Iowa driver’s license or non‑operator ID, you must use that number instead of your SSN. For online registration only, the ID must be valid (not expired).

If you don’t have one of these three, you can leave the ID fields blank. The county auditor will assign you a unique voter ID number so your registration can be processed. This is not an option for online registration.

What Happens After I Register?

After your registration is processed, you’ll receive a voter acknowledgment card confirming your registration, precinct, and polling location. This means you’re eligible to vote in the upcoming election. You can also check the status of your voter registration online.

The county auditor’s office will automatically send a voter identification card to registered voters without an Iowa driver’s license or non-operator ID.

Voter Registration for Special Groups

Some Iowans need alternative ways to register to vote. The law provides special options for these voters. This includes:

• Voters experiencing homelessness: Someone who is homeless or otherwise doesn’t have a permanent address may register using the place they usually stay, such as a shelter or a description of a location. The same identification rules apply.
• Survivors of domestic violence: Iowa’s Safe at Home program offers a substitute address, mail forwarding, and confidential voter registration for survivors of domestic violence, sexual assault, sex trafficking, and stalking. This allows them to keep their current address hidden.
• Military and overseas citizens: The federal Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) ensures Iowans abroad can register to vote and cast an absentee ballot. To register from outside the state, most citizens use the Federal Post Card Application (FPCA).
• Felons: After completion of a felony prison sentence, eligible Iowa felons must re-register to vote. All probation and parole must be served as well before re-registering.

The registration ID requirements for Iowans in these special categories are the same as for other voters.

Iowa Voter Registration Deadline

Iowa has a pre‑registration deadline of 15 days before an election. This applies to online registration and mailed forms, which must be postmarked by that date. You can also register in person up to 15 days before the election. If you miss this deadline, you can still register in person on Election Day before voting.

Election Day Registration (EDR)

Iowa allows Election Day registration at the polls. This means you can register to vote and cast a ballot on the same day. Because you’re registering and voting at the same time, you must show proof of identity and proof of residence.

Acceptable documents for both categories are provided below.

Proof of Identity

For EDR in Iowa, your proof of identity must be a valid photo ID. This may include:

• Iowa driver’s license
• Iowa non‑operator ID
• U.S. passport
• Military ID
• Tribal ID
• A signed Iowa voter ID card

Your photo ID must be current and valid.

Proof of Residence

You’ll also need to bring proof of your current Iowa address. A wide range of documents will work here. Examples include:

• Utility bill
• Bank statement
• Paycheck
• Lease
• Shelter letter (for homeless/unhoused voters)

The document you bring to prove residence must be dated within 45 days of Election Day and include both your name and address.

EDR Without Documentation

If you don’t bring the required documentation, you will have two options. They are:

• Another registered voter with ID can attest to your identity and/or address: Both of you must sign an oath affirming your identity, address, and eligibility, and acknowledging that giving false information is a felony
• If you don’t have an attester, you’ll still sign the required oath: You’ll vote by provisional ballot and must bring the missing documentation to the county auditor by the Monday after Election Day

You can provide the required identification in person or by email, fax, or mail, as long as it arrives by the deadline. If it doesn’t, your provisional ballot won’t count.

Registered Voter ID Requirements

Even if you’re already registered, you’ll still need to bring photo ID when voting in person. Any of the following forms of ID will suffice, as long as they’re valid and current:

• Iowa driver’s license
• Iowa non-operator ID card
• U.S. passport
• U.S. military ID or veteran’s ID card
• A tribal ID or document
• A signed Iowa voter ID card

As discussed above, you can either have someone attest to your identity or cast a provisional ballot if you forget to bring suitable ID. Provide ID in person or by email, fax, or mail, as long as it arrives by the deadline. If it doesn’t, your provisional ballot won’t be counted.

Does Iowa Allow Early Voting?

Yes. Registered voters can vote early in person starting 20 days before Election Day. You can vote early at county auditors’ offices. Some counties also open satellite early voting sites at locations such as libraries and community centers.

Early voting ends the day before Election Day at your county auditor’s closing time. This is usually the close of business, but some counties extend hours. You can also request an absentee ballot to vote early without going to the polls on Election Day.

Absentee Voting in Iowa

Iowa allows all registered voters to request an absentee ballot without giving a reason. You must use the official State of Iowa Absentee Ballot Request Form.

You can obtain it from:

• The Iowa Secretary of State’s website
• Your county auditor’s office
• Community groups or voter registration drives

You’ll need to provide the required information and specify the election for which you want to vote by absentee ballot.

Returning the Ballot Request Form

After filling it out, you can return it to your county auditor in person or by mail, email, or fax. They must receive your request at least 15 days before the election. You’ll receive a ballot mailed to the address you listed on your request form.

Returning Your Absentee Ballot

You can return your ballot by mail or in person to the county auditor’s office. Some counties have a single official drop box at the county auditor’s office where absentee ballots may also be delivered. Only the voter, their immediate family members, household members, or caretaker may hand‑deliver a voter’s ballot unless the voter qualifies for a delivery agent.

Delivery agents are allowed only in specific situations. Voters may designate an agent if they’re:

• Blind
• Have a disability
• Unable to read English
• Living in a health care facility, assisted living facility, or hospital
• Unable to physically return their own ballot for another valid reason

In these situations, the voter must complete an Absentee Ballot: Designation of Delivery Agent Form, which the agent submits to the county auditor along with the voter’s ballot. All absentee ballots must arrive by the time polls close on Election Day. You can track your absentee ballot here.

Polling Place Accessibility

Iowa requires polling places to be accessible to all voters. In practice, this means each voting site must have:

• Accessible entrances with ramps or level access
• Clearly marked routes into the building
• Wide aisles and voting areas for wheelchairs or walkers
• Accessible parking (when parking is provided)
• At least one accessible voting machine so voters can mark a ballot privately
• Curbside voting for voters who cannot enter the building

Voters may also bring a person to assist them, though this person may not be their employer or union representative. You can also request help from poll workers, who are trained to help voters with disabilities.

The Iowa Secretary of State’s website provides additional information to assist voters with disabilities.

Illegal Activity at the Polls

State and federal law protect every voter’s right to cast a ballot safely and without interference. While Illegal activity at the polls is rare, it’s important to know how to recognize it.

Examples of illegal conduct at polling places include:

• Electioneering too close to the polls: Campaigning, displaying political materials, or trying to influence voters within 300 feet of the polling place entrance
• Blocking access: Standing in doorways, following voters, or creating obstacles that make it difficult for people to enter or exit
• Intimidating voters: Threatening, harassing, or pressuring voters about how to vote or whether to vote at all
• Interfering with ballot privacy: Attempting to watch someone mark their ballot or asking to see how they voted
• Tampering with voting equipment: Altering, damaging, or improperly handling ballots, ballot boxes, or voting machines
• Impersonating a voter: Pretending to be another person in order to cast a ballot
• Disrupting the voting process: Causing disturbances, refusing to follow poll worker instructions, or interfering with check‑in procedures

If you see something concerning, tell a poll worker or election official immediately. They’re trained to handle problems and take action to stop illegal behavior. Do not try to handle it yourself. If you’ve already left the polling place, you can report issues to your county auditor’s office or the Secretary of State’s voter hotline at 1-888-SOS-VOTE.

You may also report serious issues involving intimidation, discrimination, and voter suppression to the U.S. Department of Justice Civil Rights Division.
