Passport Acceptance Offices in Chilton, Wisconsin

Chilton is the seat of Calumet County, a compact courthouse town in east-central Wisconsin between Lake Winnebago and Manitowoc, about half an hour southeast of Appleton. For a place its size it keeps two genuine passport acceptance points within a few blocks of each other, so most first-time applicants and families renewing before a trip never have to drive to Appleton or Green Bay to get their paperwork witnessed.

Your two choices sit at opposite ends of downtown. The Calumet County Clerk of Court works out of the historic courthouse on Court Street and takes walk-ins during regular county hours, which suits anyone who would rather not juggle an appointment. The Chilton Post Office on East Main Street handles passports by appointment, with a set walk-in window on Tuesday afternoons. Neither location issues the passport itself — both witness your signature and forward the application to a State Department processing center — so plan around routine timelines rather than same-day service.

Wisconsin has no regional passport agency, so if you are traveling within two weeks and need an expedited, in-person appointment, the nearest option is the Chicago Passport Agency, roughly a two-and-a-quarter-hour drive south. For standard trips, sticking with a local acceptance office in Chilton is the simpler path; you can compare other towns across the state on our Wisconsin passport offices page. Neither Chilton office takes photos on site, so have a compliant 2x2 photo in hand before you go.

Photos are the thing to sort out first: neither the courthouse nor the post office takes them, so stop at a pharmacy or photo studio for a 2x2 before your visit. If you want a walk-in, the Clerk of Court accepts applications any weekday during county hours; if the post office fits your schedule better, book ahead or use its Tuesday afternoon window. Children under 16 must appear in person with both parents or guardians. Current fees, what to bring and processing times are all on the Wisconsin state page.
