To renew a passport in any state, submit an application containing Form DS-82, your most recent passport, the fee and a photo to the National Passport Processing Center, as of June 2015. If you aren't eligible for renewal by mail, go to a Passport Acceptance Facility.
For mail renewal, your previous passport must be undamaged and issued within the last 15 years. You must have been 16 or older when the passport was issued. It must be in your name, unless you can legally document your name change. In that case, the applicable documents must be included in the mail application.
Form DS-82 is the Application for a U.S. Passport by Mail. The form is available online. Visit Travel.State.gov, and click on U.S. Passports and International Travel. Place the cursor over Your U.S. Passport. On the drop-down menu that appears, click on Renew a Passport.
Go to the DS-82: Application for a U.S. Passport by Mail heading, and click on Complete by Hand to print the form. Click on Complete Online and Print to fill out the form online before printing it.
Fees must be paid by check or money order. Expedited shipping carries an additional fee. The passport photo must meet the photo requirements and be stapled to the application.
