If we do not have your driver's license/state ID or your Social Security number on file, you will not be able to complete this application online unless you update your voter registration by calling 312.603.0946.

Ballot Integrity: Unless you require assistance, do not let anyone else mark your ballot; do not let anyone force or coerce you into voting for any candidate; and do not let anyone, other than a close relative or authorized messenger, mail, deliver or handle your voted ballot.
Please note: Making a false statement to obtain a mail ballot or soliciting someone to do so is considered vote fraud, a criminal offense punishable by up to five years in prison. Call 312.603.0909 to report vote fraud.
