Voter Registration in Illinois
Online Registration
Illinois offers online voter registration through the Illinois Online Voter Application (OVA). Eligible applicants need a valid Illinois driver’s license, state ID, or address confirmation. The system verifies identity and residency before finalizing the registration.
In-Person and Mail Registration
You can register by mail using the National Mail Voter Registration Form (Form NVRA) or pick up a paper form at county clerk offices, libraries, and some government offices. In-person registration is available at county clerk offices and during designated events, with same-day registration available under certain conditions.

Registration must be completed at least 28 days before an election. For example, if an election occurs in November, registration typically closes about four weeks prior. Updates or changes can be made in person or by mail if submitted before deadlines.

Required Identification to Vote

- U.S. passport
- Employee photo ID issued by a government agency or university
- Other photo IDs with name and address
If you do not have acceptable ID, you may be able to vote by signing an affidavit. Procedures vary by county, so contact your local clerk for guidance.
Early Voting and Absentee Voting
Illinois allows early voting at designated locations before Election Day. You may also request an absentee ballot if you meet certain criteria, such as being away from your precinct on Election Day, having a disability, or being a senior citizen. Ballots must be requested and returned according to specific timelines to be counted.
Requesting an Absentee Ballot
You can typically request an absentee ballot online through your county clerk’s portal, by mail, or in person. Completed ballots must be returned by the deadline, either by mail or in drop boxes where available. Always verify submission methods with your county clerk for the most current options.
Polling Place Information on Election Day
Polling locations are assigned based on your precinct. Find your polling place using your address through the Illinois State Board of Elections website or your county clerk’s site. Polls are generally open from 6:00 a.m. to 7:00 p.m. on Election Day. If you are in line when polls close, you have the right to vote.
What to Bring on Election Day
- Acceptable photo ID
- Proof of residency if required
- Voting sample or notes (political ads and sample ballots are available from the state board or county clerk)
- Reading aids, if needed
Tracking Your Ballot and Election Results
Many counties provide online ballot tracking systems so you can confirm your absentee or mail ballot has been received and accepted.
