Mailing on and off campus
Mailing Services picks up and delivers interdepartmental mail each weekday.
Campus mailing address format
On-campus mailing addresses use a PO Box number—never a street address or building name and room number. The PO Box number begins with the digits 64, followed by a unique 4-digit delivery code for each department. The delivery code also appears in the extended zip code.
How to address on-campus mail
- Line 1: Recipient name
- Line 2: Department name
- Line 3: PO Box 64XXXX
- Line 4: Pullman, WA 99164-XXXX
XXXX represents the 4-digit delivery code for the department.

- Cooper Publications Building room 40 – 4:00 p.m. (Mail is transported to the U.S. Postal Service office at 4:15 p.m.)

Need to know your mail arrived?
Priority Mail offers delivery confirmation most times at no charge. You’ll get a tracking number that lets you check online to see if the item has been delivered.
Need signature confirmation?
If you want the individual who receives the package (though not necessarily the addressee) to sign for it, your mail service options include:
- Priority Mail
- First-Class Mail
Need a return receipt?
Choose one of these services:
- Certified Mail (The recipient at the delivery address signs to receive the item.)
- Insured Mail (The recipient must sign for the item and you can be compensated if the item is lost or damaged.)
- Registered Mail (Every person who handles the item must sign a form.)
- Express Mail (You get one- or two-day delivery and a recipient at the delivery address signs for the item.)
Regardless of weight, there must be a customs form filled out for all international items (including APD, FPO, and DPO) that are not documents. Contact Mailing Services for the USPS definition of what is a document.
