Some U.S. Postal Service offices serve as passport acceptance facilities as of 2015, according to the U.S. State Department. Libraries and county or city offices may also accept passport applications. The State Department provides locator services for passport acceptance facilities and passport agencies on its website.
Passport acceptance facilities handle routine and expedited requests for passports. Some offer walk-in services, while others require appointments. Passport agencies handle emergency requests; those involving immediate travel require appointments. The State Department recommends using a passport agency rather than a passport acceptance facility if a passport is needed for international travel within two weeks or to obtain a foreign visa within four weeks.
