Voter registration may also be completed at the Oak Brook Public Library at 600 Oak Brook Road, or at the Election Commission office at 421 North County Farm Road in Wheaton, Illinois.

Requirements for New Voter's Registration:
In order to register to vote, a person must meet three qualifications:
  • Must be a citizen of the United States.
  • Must be a resident of the precinct for 30 days as of the next election.
  • Must be 18 years of age by election day.
Registering to Vote:
This service is available at municipal complex during regular business hours for both Cook and DuPage County residents.
  • You must provide two forms of identification, one with the current residence. Residence is the permanent place of abode (where applicant actually lives). No one may register from a business, mailing center or Post Office box.
    • If the resident is a naturalized citizen, naturalization information must be provided.
    • If you are unable to produce identification with the current residence, yet you are able to produce sufficient identification to verify identity, you will need to complete an "Affidavit of Residence."
    • The registrar will administer an oath in order to swear (or affirm) your application.
Transfer of Voter Registration:
A voter who is already registered within their county under his / her current name, and who has merely moved from one address to another within the same county, may transfer that registration to the new address by filling out a new voter registration form.

Cancellation of Previous Registration:
If you are registered in another county or state, or are registered under another name, the old registration must be canceled before registering in the new county. You may cancel your old registration on the voter's application form by completing the cancellation area on the registration form.

All applications are mailed within seven days to the DuPage County Election Commission or the
 Cook County Clerk's Election Department. Voter registration cards are mailed by the DuPage County Election Commission or the Cook County Clerk's Election Department directly to the registrant at their home address in approximately four to six weeks.
