Illinois ID requirements for voting by mail

COVID-19 Advisory: Vote by mail applications will be mailed to all recent voters (defined as voters who applied to vote in 2018, 2019 or 2020) for the November general election. Other voters can request an absentee ballot here. https://elections.il.gov/ElectionOperations/VotingByMailAgreement.aspx

Who is eligible to request and vote a Vote by Mail Ballot?

Any registered Illinois voter may apply for a Vote by Mail ballot. No excuse is required.

First-time voters

When you register to vote or vote for the first time in a federal election in your state, you must prove who you are:
  • If you register to vote in person, you must show a driver’s license, state ID, or provide the last 4 digits of your social security number (SSN), if you have one.
  • If you registered by mail and did not include your state’s driver’s license number or the last 4 digits of your SSN, you must show an acceptable form of ID (see below) at your polling place.
  • If you apply for an absentee/vote by mail ballot and did not include your state’s driver’s license number or the last 4 digits of your SSN when you registered by mail, you must include a copy of an acceptable ID (see below).

Here is a list of acceptable IDs: Documents that prove who you are

Your state may have other ID requirements for voting in person or for absentee/vote by mail ballot.
