Voter Registration

Same-Day Registration: YES — you can register at the polls on Election Day.

Registration Deadline: Regular (paper) registration closes 28 days before the election; online registration closes about 16 days before the election. Grace period (same-day) registration is available from 27 days before through Election Day. For the March 17, 2026 primary: mail postmarked by Feb 17, 2026 and online by March 1, 2026. For the Nov 3, 2026 general: paper by Oct 6, 2026 and online by Oct 18, 2026. Photo ID Required to Register: No Accepted IDs: Illinois driver’s license number (required for online registration), Illinois State ID card number (required for online registration), Last 4 digits of Social Security number, For in-person/grace period registration: two forms of ID, one showing current address, Photo ID (driver’s license, state ID, passport), Student/university ID, Current utility bill, bank statement, paycheck, government check, or other government document, Residential lease or rental contract, Postmarked mail delivered to current address

Registration Links

Notes: Online voter registration requires an Illinois driver’s license or state ID. No photo ID is needed to register by mail or in person, but if you register by mail without a driver’s license, state ID, or SSN and have never registered in that jurisdiction, you must include a copy of a photo ID or a current document (utility bill, bank statement, government check/document) showing your name and address. Same-day registration is called ‘grace period registration’ and requires two forms of ID, one showing current address. Grace period voters cast ballots at the election authority’s office or designated locations, not necessarily their regular polling place. Illinois allows pre-registration for 16-year-olds. Dates vary by election; confirm exact deadlines for your specific election.

Birth Certificates

A birth certificate may be needed to prove citizenship or obtain other identity documents.

Issuing Agency: Illinois Department of Public Health, Division of Vital Records Fee: $10 for a short-form certified copy; $15 for a long-form certified copy (information collected at time of birth); $2 each additional copy per official IDPH page. Note: Illinois Legal Aid lists $15 first copy and $4 each additional. Free for people who are homeless, in family violence shelters, or recently incarcerated/soon-to-be-released in Cook County jail or IDPH. Verify exact amount for your record type. Standard Processing Time: Approximately 12 weeks from when IDPH receives your paperwork (per official IDPH notice) Expedited Option: verify – IDPH does not clearly list an expedited option; VitalChek online orders offer faster shipping options (e.g., 2-day air, UPS air) for additional fees. In-person requests at a county clerk may be faster.

How to Request

  • Request Online
  • By Mail: verify – sources list two different addresses: ‘110 W Lawrence Ave., Springfield, IL 62704-2610’ (official IDPH page) and ‘925 E. Ridgely Avenue, Springfield, Illinois 62702-2737’ (Illinois Legal Aid). Confirm current address with IDPH before mailing.

Notes: You will not receive updates from IDPH during the 12-week processing time. Only certain people may obtain a birth certificate; photo ID is required. If born in Cook County or a specific city (e.g., Springfield after Jan 1, 1985), you may need to use the county or city clerk instead. County clerk fees differ (e.g., Madison County charges $20 first copy). Birth records are free for people who are homeless/unhoused, residents of family violence shelters, or people recently released from or soon to be released from Cook County jail or the Illinois Department of Corrections. VitalChek and other third-party sites (StateVitalRecords.org, GoCertificates.com) add processing fees.

Proof of Citizenship Documents

You may need proof of citizenship to register to vote or to obtain a REAL ID.

Accepted Documents

  • US Passport
  • Certificate of Naturalization
  • Consular Report of Birth Abroad
  • US Birth Certificate

How to Obtain Citizenship Proof

Illinois does NOT require proof of citizenship to register or vote. To register, you sign a sworn statement that you are a US citizen. Illinois requires either your Driver’s License/State ID card number or the last 4 digits of your Social Security Number. If you have neither and are registering by mail for the first time, include a copy of a current photo ID OR a current utility bill, bank statement, government check, paycheck, or other government document showing your name and address. If you need federal proof of citizenship for other purposes: for a US Passport, file Form DS-11 with your original US birth certificate (or Certificate of Naturalization/Consular Report of Birth Abroad if not born in the US) as proof of citizenship. To become a naturalized citizen, file Form N-400 with USCIS, pay the fee, attend a biometrics appointment, complete an interview, and take the Oath of Allegiance.

For US Citizens Abroad

verify

Notes: IMPORTANT: Illinois does NOT require documentary proof of citizenship to register or vote. Under the National Voter Registration Act, voters only sign a sworn statement affirming US citizenship. Illinois does not require photo ID at the polls, though first-time voters or those with incomplete registrations may need to show ID. A March 25, 2025 federal executive order sought to require documentary proof of citizenship nationwide, but Illinois officials stated they will not require it. This is a recent legal change that is contested and may be subject to litigation — verify current status. To replace a lost Certificate of Naturalization, file Form N-565 with USCIS and pay the fee. Contact USCIS (www.uscis.gov) directly for naturalization procedures.

Voting Laws & Legal Resources

Illinois does not require voters to present identification when voting, in most cases. Identity is verified by matching your signature against your registration records. The main exception applies to first-time voters who registered by mail and did not provide a driver’s license number, state ID number, or the last four digits of their Social Security number. Those voters must show ID showing their name and address before voting. Accepted forms include a current photo ID (driver’s license, state ID, or passport), a utility bill, bank statement, paycheck, government check, or other government document with your name and address. Polls are open from 6:00 a.m. to 7:00 p.m. Central Time, and anyone in line when polls close must be allowed to vote.

Recent Law Changes

  • 2025: In March 2025, President Trump issued an executive order directing federal agencies to require voters to show documentary proof of U.S. citizenship when registering. Illinois officials stated the state will NOT enforce this requirement.
  • Impact: Illinois voters do not need to show proof of citizenship to register. Under the National Voter Registration Act, registrants only sign a sworn statement affirming U.S. citizenship. Illinois also continues to not require photo ID at the polls.
  • 2025: A proposed federal SAVE America Act would impose stricter voter ID requirements. According to research, complying would require a complete overhaul of Illinois law, since Illinois currently requires no ID document (identity verified through signature matching).
  • Impact: If enacted, this could significantly change Illinois’s no-document-required system. As of the sources, this is proposed and not yet in effect — verify current status before relying on it.

Voting Rights Law Firms

If You Are Denied the Right to Vote

Know your rights. You have the right to vote if you are eligible. If denied, do NOT leave — ask for a provisional ballot.

Denied Enroute to the Polling Place

  1. Step 1: Know your rights. Illinois polls are open 6:00am to 7:00pm. If you are in line by 7:00pm, you have the right to vote.
  2. Step 2: If a polling place opened late, equipment was not set up, or poll workers did not show, stay in line and do not leave.
  3. Step 3: You cannot be denied the right to register or vote based on race, color, ethnicity, language minority status, national origin, religion, sex, sexual orientation, or income (Illinois Constitution).
  4. Step 4: If you face intimidation, obstruction, or wrong information while trying to reach the polls, call the Election Protection Hotline at 1-866-OUR-VOTE (1-866-687-8683).
  5. Step 5: Document what happened — time, location, and names of anyone involved.

Denied at the Polling Place

  2. Step 2: Confirm you are registered at your current address and that you are at the correct polling place.
  3. Step 3: If an Election Judge challenges your right to vote, or you lack required ID, ask for a provisional ballot. Poll workers should give you instructions on making sure it is counted.
  4. Step 4: If you registered by mail without providing ID, or you are registering/updating your address the same day you vote, you may be asked for ID (two forms of ID for first-time Election Day registrants).
  5. Step 5: If you recently moved, ask a poll worker whether you can update your registration and vote a regular ballot, or if you must vote at your old location or a central polling place.
  6. Step 6: Call the Election Protection Hotline at 1-866-OUR-VOTE (1-866-687-8683) for help.

Provisional Ballot: In Illinois, if you are not allowed to vote a regular ballot — for example, because your right is challenged by an Election Judge, you registered by mail without providing ID, or you don’t have required ID when needed — you can still cast a provisional ballot. The poll worker should give you instructions on what you need to do (such as providing ID afterward) to ensure your ballot is counted.
