📖 About this office
The New Castle Downtown Post Office at 501 Delaware Street occupies a handsome New Deal-era federal building in the heart of historic New Castle, steps from the courthouse green and the waterfront district that dates to the city's colonial founding. Applicants who live near the older residential neighborhoods of New Castle proper will find this location a natural first stop before heading elsewhere in the county.
Like all USPS acceptance facilities, passport services here require a scheduled appointment made through the USPS online scheduler. The acceptance agent reviews your completed DS-11 or DS-82 form, checks your identity documents, and forwards your packet to the National Passport Processing Center. The downtown setting means on-street and nearby municipal parking is available, though spaces fill quickly on weekday mornings.
This office serves a distinct community from the Quigley Boulevard location — its walk-in postal counter, historic architecture, and proximity to city hall make it a familiar civic hub for longtime New Castle residents applying for their first passport or renewing ahead of an international trip.
