Must be a resident of the county, and prior to voting in an election, must have resided at his or her residential address for at least 30 days prior to the date of the election.
Must be at least 18 years old or will be 18 by the date of the next general election.

To register, a person who meets the voting qualifications must sign and complete a voter registration application. When completing the application, applicants must provide their full name, residential address, date of birth, and citizenship status. In addition, the application must be signed. Failure to complete a required field on the form will delay the processing of the application. After completion, the application should be mailed to the board of elections in the county in which the applicant resides. If the application is for new registration in a county, the form must be submitted prior to the voter registration deadline. The board of elections must receive the original signed application.

Voter Registration Drives

Voter registration services may also be offered by any individual, group or organization that desires to conduct a voter registration drive. No special training or permission is needed to conduct a voter registration drive; however, organizers should follow the guidelines set out in our Voter Registration Drives: A Citizen's Guide brochure. County boards of elections can provide voter registration supplies to drive organizers in limited quantities (less than 1000 blank forms). If a larger quantity of forms is needed, organizers may request the forms directly from the State Board of Elections. Download the Voter Registration Drive Supplies Request Form if you plan to conduct a voter registration drive. Applications collected at voter registration drives must be delivered to the appropriate county board of elections by the voter registration deadline.

Any applicant that submits a voter registration application at a voter registration drive and does not receive a voter card in the mail within two weeks of this submission, should notify their county board of elections or the State Board of Elections immediately.
