Mosier does not have USPS delivery to addresses within city limits; residents must get a PO Box and pay for it either semi-annually or annually. Just walk in to the post office and say you need to get a PO Box.
Complicating matters is that some Fedex and UPS ground packages are also delivered to the post office. If you run into a situation where a PO Box is not accepted, use your street address with your PO Box added to the end like an apartment, for instance: 123 Main St #789
1001 Third Avenue
Mosier, Oregon 97040
See the official USPS page for the latest information about this location, including postal services available.
The lobby is open all day every day, so you can always access your PO Box.
