how long is a passport card good for
Adult Card Validity. Any United States citizen over the age of 16 can apply for an adult passport card. Like passport books, adult passport cards remain valid for 10 years from the date of issue. The date your passport card was issued is printed on the front of the card along with the expiry date, making it easy to check how much validity is left. Childrenâs passport cards are only valid for five years.
