Casper Post Office (North Forest Drive)

The Post Office on North Forest Drive sits on Casper's east side, a short hop off East Second Street and convenient for anyone coming in from Evansville or the Hilltop neighborhoods. It is one of two USPS branches in the city that handle passport applications, and its extra parking makes it an easy stop when you are carrying a folder of documents and a squirming child in tow.

Staff here process first-time adult passports, all minor applications, and the in-person paperwork for name changes and replacement of a lost or stolen book. Because passport work is handled by appointment rather than at the regular retail window, you reserve a slot in advance through the U.S. Postal Service scheduler and arrive with your completed DS-11, proof of citizenship, and a photo ID. Photos can be taken on site, which spares a second errand.

If this branch is fully booked, downtown Casper has a second postal acceptance point and the Natrona County Library also accepts applications, so it is worth checking all three when your travel date is firm. For statewide context and the federal steps, see our Wyoming passport guide.

Bring two forms of payment: the State Department fee and the USPS execution fee are collected separately, and the execution fee can be paid by card. Double-check your citizenship evidence is an original or certified copy before you drive over, since a plain photocopy will send you home. Compare this branch with the other Casper acceptance locations if you need an earlier slot.
