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.

UW Box Numbers

The University of Washington in cooperation with the USPS uses a six digit box number format. All UW box numbers begin with 35____. The last four digits are unique to each office and comprise the last four digits of the ZIP code. UW Box numbers for faculty and staff are listed in the UW Faculty/Staff/Student Directory. UW Box numbers for departments are listed in Departmental Box Numbers.

A complete UW Seattle campus ZIP code is 98195 + the last four digits of the box number. For example, the zip code for box number 352700 would be: 98195-2700
