What counts as ID
If you've voted in Illinois before, you don't need to provide ID to vote.
If you're a first-time voter who registered by mail and didn't provide your driver's license number, state ID number, last 4 digits of your Social Security number, or a copy of a current ID or government document that shows your name and address when you registered, you'll need to provide one of these when you vote:
- copy of a current and valid photo identification
- copy of a current utility bill, bank statement, government check, paycheck
- student ID AND either a residential contract/lease or any postmarked mail delivered to your current residence address
- other government document that shows your name and address
Voters without ID: If you are unable to provide ID, you will be able to vote a provisional ballot. After voting provisionally, you will be told how to submit additional proof of registration to the election authority. The additional information must be received by your election authority no later than the close of business on the seventh day following the election.
Before you can vote
Registering
Ways to register:
Illinois lets you pre-register from age 16, so you are on the roll the moment you turn 18.
Who can register, and what you need
To register in Illinois you must:
- be a United States citizen
- 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 Consolidated or General Election or 17 years old to vote in a Consolidated Primary or General Primary Election if you will be 18 by the time of the Consolidated or General Election
- not 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
Which primary can you vote in?
You are NOT required to register with a party to participate in Illinois partisan primary elections. If you are an unaffiliated voter, you are allowed to publicly choose the party ballot you wish to vote on primary election day.
