For the most current voting information, please visit the Cook County Clerk’s Website.

Voter Registration Status

If you are already registered to vote, you may check your voter registration status here, as well as your polling place location and sample ballots.

When to Re-Register

Your registration is permanent unless you move or change your name.

Address changes

If you have moved within suburban Cook County, you must transfer your registration by re-registering. You may choose to write your new address on the back of your voter identification card and mail it to the Clerk’s downtown Chicago office.

You must re-register with the new local election authority or county clerk if you move to an address outside suburban Cook County.

Name changes

Voters who legally change their name, but not their address, do not have to re-register. If you have changed your name, you can vote after updating your information at the polls.

Grace Period & Election Day Registration and Voting

If you miss both voter registration deadlines, you may still register to vote during the Grace Period or on Election Day. However, registration locations are limited.

1. Grace Period Registration and Voting: February 21 – March 19 for the March 20, 2018 Primary Election

Grace Period Registration and Voting extends the registration period by allowing voters to register and vote until the Monday before an election. Guidelines limit when and where grace period registrants can vote – during the 27 day grace period, voters must register and vote in person at one of the Clerk’s designated grace period locations.

Individuals wishing to vote during the grace period must bring two pieces of identification to register, one with a current address. Grace period registrants must immediately cast their ballot after registering to vote.

2. March 20, 2018 Election Day Registration and Voting

On March 20, 2018, voters who are not registered to vote can register and vote at their home precinct only, on Election Day. Any voter who is not registered and needs to know where to go to register and vote on Election Day can utilize the Clerk’s online Your Voter Information Tool to find their proper polling place by address or birthday.

Voter qualifications

To register to vote, you must be:

  1. A U.S. citizen
  2. At least 18 years old by the general election
  3. A resident of your precinct at least 30 days prior to Election Day

You also must display two pieces of identification. Neither needs to be a photo ID, but one must include your current address. Acceptable forms of ID include:

  • Illinois driver’s license
  • Illinois state ID
  • Employee or student ID
  • Credit card
  • Social security card
  • Birth certificate
