Illinois offers online voter registration. You can register by mail to vote in Illinois by printing a voter registration form, filling it out, and mailing it to your local election authority. You can also register to vote in person if you prefer.

Who can register to vote?

To register in Illinois you must:
  • be a citizen of the United States
  • be a resident of Illinois and of your election precinct at least 30 days before the next election
  • be 18 years old to vote in a General Election or 17 years old to vote in a primary election if you will be 18 by the time of the General Election
  • cannot be serving a sentence of confinement in any penal institution as a result of conviction of any crime
  • not claim the right to vote anywhere else

Can I register to vote online?

  • Illinois offers online voter registration.
  • You should know: you need an Illinois driver's license or ID and a Social Security number to use Illinois's online voter registration system. If you don't have an Illinois-issued ID, you can still register by mail to vote.

Can I submit voter registration forms by mail?

Yes, you can print, complete and mail the National Voter Registration Form to register to vote in Illinois.

Here’s some advice on how to complete the form:
  • Box 6 - ID Number
    • You must provide your Illinois driver's license number or state ID card number.
      • If you do not have a driver's license or state ID, include at least the last four digits of your Social Security number (SSN).
      • If you do not have an Illinois driver’s license, state ID, or SSN, write "NONE.” A unique identifier will be assigned to you by the State.
      • If you do not have a driver’s license, state ID, or SSN and you have not registered in Illinois before, you should include with your mail-in registration application a copy of one form of proof of identification.
      If you do not provide identification information, you will be required to provide election officials with one form of identification the first time you vote at a voting place or by absentee ballot. Find forms of proof of identification from the Illinois State Board of Elections.
  • Box 7 - Choice of Party: Illinois does NOT require that you register with a party to participate in partisan primary elections. Illinois allows unaffiliated voters to publicly choose the party ballot they wish to vote on primary election day.
  • Box 8 - Race or Ethnic Group: Leave blank. This information is not required.
  • Review the "Who can register to vote?" section above and check that you're eligible.
  • Sign the form.
  • Send the completed form to your local election authority

What if I'm registering to vote for the first time in your jurisdiction and are mailing this registration application?

  • If you are registering to vote for the first time in your jurisdiction and are mailing this registration application, Federal law requires you to show proof of identification the first time you vote. Proof of identification includes:
    • A current and valid photo identification or
    • A current utility bill, bank statement, government check, paycheck or government document that shows your name and address.

How do I vote if I'm in the military or live overseas?

Active-duty military, their families, and overseas citizens can register to vote and request their absentee ballot using the Federal Post Card Application (FPCA). The FPCA process is done by mail, but your state may offer other options to request and return ballots. Please contact your local election authority for more information about delivery and return methods, including email, fax, and state online portals. To follow the FPCA process:
  1. Fill out the Federal Post Card Application (FPCA), or download a copy. Your local election authority may have questions, so please provide an email address or phone number where they can reach you.
  2. Send the application to your local election authority.
  3. It is never too early to submit an FPCA! Please do so as soon as possible.
  4. Please fill out and send back your ballot as soon as you receive it.
  5. States begin mailing absentee ballots at least 45 days before Election Day. If you haven't received your ballot by 30 days before Election Day, contact your local election authority.
If after submitting your FPCA, your ballot does not arrive, contact your local election authority first. Then:
  • You can still vote using the Federal Write-In Absentee Ballot (FWAB). Print, sign, and mail your FWAB to your local election authority.
  • If you mail a FWAB and then receive your regular absentee ballot, you should complete and mail your absentee ballot also. Election officials will ensure that only one ballot is counted.
The Federal Voting Assistance Program offers additional information on military and overseas voting in Illinois. You can also call 1-800-438-VOTE (8683) or email vote@fvap.gov
