Click here for a Voter Registration Application A person who is eligible to register to vote must be at least 18 years old, a United States citizen, and a resident of Oklahoma. You must fill out a voter registration application form.

The voter registration application form asks for: your name and address your political affiliation your date of birth the last four digits of your Social Security number. You must sign and date the oath printed on the form. After filling out and signing the voter registration application form, mail it to the State Election board. The form is already addressed, but you must add a first-class postage stamp. You do not become a registered voter until the county election board in the county where you live approves your voter registration application. When your application is approved, the county election board mails a voter identification card to you. Your voter identification card lists your name, address, political affiliation, and the polling place for your voting precinct. When you receive your voter identification card in the mail, look at it carefully and call the county election board if there are any errors. Keep your voter identification card in a safe place and always take it with you when you go to vote. If the county election county board cannot approve your voter registration application, a letter will be mailed to you, explaining why your application was not approved and tells you what steps to take to become registered. You may be able to return the letter with some additional information, or you may need to fill out and send in a new application form. You may send in a voter registration application form at any time. However, the county election board cannot issue voter identification cards during the 24 days before an election. If you become eligible to register to vote during a period that begins 60 days before an election and ends on election day, you may send in your application early. The election must be one in which you will be eligible to vote if registered. For example, if your 18th birthday occurs 30 days before an election, you may send in a voter registration application before your birthday, but no earlier than 60 days before election day. The county election board then mails your voter identification card to you after your birthday. After you become a registered voter, you may need to change your registration. Changes you may need to make include: Your name Your address Your political affiliation You must fill out a new voter registration application form to change your voter registration. Follow the instructions on the form about changing your registration. You may change your voter registration at any time, with one exception: You cannot change your political affiliation between June 1 and August 30 in even-numbered years.
