📖 About this office
The Downtown Casper Post Office anchors the historic core on East B Street, within easy walking distance of the county offices, the library, and the shops along Second Street. For residents who work downtown, it is often the most practical place to handle a passport without crossing town.
This branch accepts first-time adult applications and minor applications, and its staff can also take your passport photo during the visit. As at every USPS acceptance point, the work is done by appointment rather than at the walk-up window, so you book a slot ahead through the Postal Service scheduler and bring your unsigned DS-11, original citizenship proof, and identification.
Downtown parking can be tight around midday, so allow a few extra minutes to find a spot. When timing matters, it helps to check availability across all of Casper's acceptance locations and to review the federal processing steps in our Wyoming passport guide before you go.
💡 Good to know
Sign nothing on your DS-11 until the acceptance agent tells you to — the oath is administered in front of them. Downtown parking fills at lunchtime, so an earlier appointment is usually easier. If this branch is booked out, the North Forest Drive office and the Natrona County Library handle the same applications.
