Register at School or Home
Students have a decision about where to register to vote.
You have a right to register to vote at the address you consider the place where you live, whether that is your family's home or the place where you attend school. You should update your registration anytime this home address changes.
You may only be registered and vote in one location.
What Type of ID Do I Need to Register?
Online Registration: If you are registering to vote online, you must provide your Iowa driver's license number or Iowa ID card number, as well as the last five digits of your Social Security number. Please see the link above for Iowa’s online voter registration portal.
Paper Voter Registration Application: Iowa’s paper voter registration form asks you for your Iowa driver’s license number, Iowa ID card number, or the last four digits of your Social Security number. Be sure to provide one of these numbers if you have it.
Same Day Registration: Residents of Iowa may register to vote and cast their ballot at the same time at the polls on Election Day. To register and vote same day, you must produce a photo ID that is current, valid, and contains an expiration date, such as:
Iowa driver’s license, non-driver state ID card, or Iowa Voter ID card
Out-of-state driver’s license or state ID card
Student ID issued by Iowa high school or college
U.S. military ID
ID card issued by your employer
If your photo ID does not contain your current address, you must supplement your photo ID with acceptable proof of residence that contains your name and current address that is dated or describes terms of tenancy current to within 45 days of registration, including but not limited to:
Utility bill (including cell phone bill)
Government check or other government document
Property tax statement
If you do not have any of these IDs or documents, a registered voter from your precinct may attest that you are who you say you are and that you live in the precinct. This requires you and the registered voter to sign an oath swearing that your statements are true.
What Type of ID Do I Need to Vote?
Iowa voters are required to show an ID before voting. Acceptable photo IDs include the following:
Iowa driver’s license or non-driver state ID card
Iowa Voter ID card
U.S. military ID or Veteran ID
Tribal ID or document
If you do not have one of the above forms of ID, you may vote by having a registered voter sign an oath attesting to your eligibility to vote or by using other forms of proving your identity and residency as listed above in the Same Day Registration section of this guide.

How Can I Vote?

Mail-in Ballot Application Deadline: Applications for a mail ballot must be received by your county auditor’s office by no later than 5:0opm on the 15th day before Election Day.
Completed Mail-in Ballot Return Deadline: Once you have completed your mail-in ballot, you may return it by mail or in person at your county auditor’s office.

Early In-person: Early in-person voting begins no more than 20 days before an election at your county auditor’s office. Check with your county auditor’s office for information about locations and times.
Election Day: Election Day sites will be open from 7:00 am until 8:00 p.m. If you are in line by the closing time then you have the right to vote. Eligible voters who have not registered to vote by election day may still register to vote and cast their ballot at their polling location on election day. Please see the above information on same-day registration for more information.
Individuals who register and vote same day will be able to cast regular ballots unless they are voting in a location that does not have electronic poll books. Election Day registrants in voting locations without electronic poll books will cast a provisional ballot that will count as long as their name does not appear in a felon database. No action is needed on the part of the voter to make these ballots count. Most Iowa precincts have electronic poll books.
Voters with disabilities may vote curbside. For more information, visit: https://sos.iowa.gov/disabilities.html

Where you register to vote will not affect federal financial aid such as Pell Grants, Perkins or Stafford loans, or your dependency status for FAFSA.
Does Registering to Vote Affect my Status as a Dependent on My Parents’ Taxes?
Being registered to vote at a different address from your parents does not prevent them from claiming you as a dependent on their taxes.
