An expired U.S. passport originally issued after the age of 16 is eligible for renewal for up to 15 years after the original date of issue, as long as the undamaged, expired passport is submitted along with the application. The name on the old and new passports must match, unless documentation for any legal name changes since the original passport was issued is sent in along with the renewal application.
Passports can be renewed by mail or in person at a passport agency. Individuals age 15 and under have to apply in person, with a parent or legal guardian. Additionally, a person who has unpaid child support totaling over $2,500 cannot obtain or renew a passport.
The old passport is returned to the applicant once the passport renewal has been processed. To renew a passport by mail, the applicant must have an address in the United States or Canada.
