Obtain a renewal for your passport card if you currently have a passport card. Apply through a form DS 82 which is found online, at a United States Post Office or through a passport agency. To apply through the form DS 82, the citizen must have a current passport card less than 15 years old and the card must have been obtained when the citizen was over the age of 16. Fill out the form and take the current passport card, and fee money, to the Post Office or passport agency to file a renewal.
Apply for a new passport card in person. New applicants will fill out a form DS 11 to apply for a new passport card. The application can be found online, at a Post Office or a passport agency.
Visit the Post Office or passport agency once the form DS 11 is completed. In addition to the form, you will need proof of U.S. citizenship such as a birth certificate, a current identification card such as a driver's license, photo for the passport card and the fee for the passport card.
