Clinton Post Office

The Clinton Post Office sits downtown at 300 S. 1st St., a few blocks from the Mississippi riverfront that gives this Iowa city its character. As the only U.S. Department of State passport acceptance facility inside the city limits, it is where most Clinton-area residents begin a first-time application or replace a lost or stolen book before a trip.

Staff here verify your identity, witness your signature on Form DS-11, and forward the sealed application to the State Department. Because this is an acceptance point rather than a regional agency, the office handles the intake step only; the actual passport is printed and mailed by the federal government afterward.

Clinton residents comparing options can review every listing on our Clinton passport page, or look statewide across passport offices in Iowa if a nearby town is more convenient.

Passport service at USPS counters runs by appointment, so book a slot online through the Postal Service before you visit rather than assuming walk-in availability. Bring proof of citizenship, a photo ID, and a photocopy of that ID. If you also need the required photo, ask when you schedule, since the counter can take it during the same visit.
