Each UW department (or building, such as a residence hall) has its own USPS campus box and ZIP+4 code. If you are sending mail or shipping packages using the USPS, you will use campus box numbers with the format above. If you are using another shipper, use the format above without the campus box number.
The best way to guarantee that you have the correct address is to contact the addressee via email or telephone first and request their address.
