Renewal

Passports are renewed by the individual via mail using form DS-82 when: 

Your most recent U.S. passport book and/or U.S. passport card is available to submit; your most recent U.S. passport book and/or U.S. passport card for which you are renewing has not been lost, stolen mutilated or damaged; you were issued your most recent U.S. passport book and/or U.S. passport card within the past 15 years; you were at least age 16 when your most recent U.S. passport book or U.S. passport card was issued; you still have the same name, or can provide legal documentation to support the name change.

If your passport has been altered or damaged, you cannot apply by mail; you must apply in person.
