Who can register to vote in Illinois
In general, you need to be a U.S. citizen, meet the state’s minimum age requirement by Election Day, and live in Illinois. Illinois sets its own rules on residency length and on how voting rights work for people with past convictions, so read the specifics on the official state page before you fill anything out.
Not 18 yet? Many states let younger people pre-register so they are ready on their birthday. See our guide to registering to vote at 17 and confirm what Illinois allows on vote.gov.
If you are a student, your choice of home address or school address can matter. Our college students voting guide explains how to think it through.

How to check or update your registration
Do not assume you are registered just because you voted once. Moving, changing your name or going a long stretch without voting can all affect your status. A quick check now can save you a headache later.
Check your status
Use the official Illinois voter lookup, which you can reach through vote.gov or your state election office. Enter your information, confirm your name and address, and note your assigned polling place and ballot details when they are available. Our voter registration status guide covers the process in plain language.
Update your information
If you have moved, changed your name or want to update your details, submit the update through the same official channels you would use to register. Do it as early as you can. We are working on a dedicated guide to updating your registration after a move, so look for our guide to updating your voter registration after moving soon.
ID basics for Illinois voters
Identification can come up in two places: when you register and when you vote. The rules differ by method, and they can change, so we are not going to hand you a checklist that might be out of date.
Here is what we recommend. Before you register, look at the official Illinois page linked on vote.gov to see what information the online or paper form asks for. Before you vote, confirm what you need to bring to your polling place or what to include with a mail ballot. For a national look at how states handle this, see our voter ID requirements by state guide.
Take action: Open vote.gov/register/illinois right now, check your status, and text one friend or family member to do the same. Two minutes today can mean two more votes in the next election.
Early voting and voting by mail in Illinois
Illinois gives voters options beyond Election Day. Depending on the election, you may be able to vote early in person or request a ballot by mail. These options can be a lifeline if you work long hours, care for family or just want to avoid a crowded polling place.
The details, including when early voting starts, where to go and how to request and return a mail ballot, are set by the state and your local election authority. Confirm them with your state election office through vote.gov. For explainers, see our guides on early voting and how to vote by mail, and learn how to find your polling place.
The 2026 midterms are on Tuesday, November 3, 2026, with all 435 House seats, about a third of the Senate and 36 governors on the ballot. If you are reading this before that date, check your options right away. Our 2026 midterm elections guide explains what is at stake.
Every election is a chance to show up for the neighbors, schools and services we care about.
