Finding the exact mailing address and postal codes for the University of Southern California can be confusing because the institution spans multiple campuses and residential neighborhoods in Los Angeles. The primary postal code for the main campus is 90089, centered at 3550 S. University Avenue, but incoming mail routing depends heavily on whether a building sits directly on campus or in the surrounding North University Park residential area, which uses 90007.
Knowing the correct recipient format ensures your letters and packages arrive without delay. Whether you're sending official documents, paying tuition fees, or shipping care packages to students, getting the numbers right matters.
Main Campus Address and Postal Codes
The main campus, officially known as the University Park Campus (UPC), sits just south of downtown Los Angeles. General university correspondence, administrative offices, and many academic departments use the primary campus locator.
- Primary Street Address: 3550 S. University Avenue, Los Angeles, CA 90089
- General ZIP Code: 90089
- Primary Geographic ZIP Code: 90007 (surrounding community)
The main zip code 90089 is unique because it is assigned specifically to the university campus footprint by the United States Postal Service. Mail addressed with 90089 routes directly through internal university sorting systems once it reaches campus postal facilities.
Health Sciences Campus Location
If you're trying to reach medical facilities, researchers, or students enrolled in healthcare programs, you need a completely different location. The Health Sciences Campus (HSC) is located northeast of downtown Los Angeles, several miles away from the main undergraduate hub.
- Street Address: 1930 E. Chicago Avenue, Los Angeles, CA 90033
- Primary ZIP Code: 90033
- Key Facilities: Keck School of Medicine, Keck Hospital of USC, and associated biomedical research laboratories.
Using the main UPC zip code for medical shipments will cause severe delivery delays. Always verify whether your recipient works in undergraduate academics or health sciences before dispatching mail.
Student Housing and Residence Hall Mail Formatting
Mailing packages to students living on campus requires precise formatting. The university provides specific guidelines based on whether the residence hall sits inside the 90089 boundary or the 90007 boundary.
University Park Campus and USC Village Buildings (90089)
Halls located within the gated core or the USC Village utilize the primary 90089 postal code, often paired with a specific mail stop or building code. For example, mail to Pardee Tower requires the street address 614 Hellman Way, Los Angeles, CA 90089. Cale and Irani Residential College in the USC Village uses 929 W. Jefferson Blvd, Los Angeles, CA 90089.
North University Park Apartments (90007)
Many university-owned apartments and Greek houses located just outside the formal campus gates fall under the 90007 postal code. Buildings like Cardinal Gardens (3131 McClintock Avenue) and Annenberg House (711 W. 27th Street) require Los Angeles, CA 90007.
Important Postal Rule: The US Postal Service doesn't forward mail or handle change-of-address requests for traditional campus housing addresses inside the 90089 zone. Students must update their shipping addresses manually when moving off campus.
Step-by-Step Guide to Addressing Student Mail
Sending a package to a student living in campus housing requires strict adherence to format standards. Leaving off a room number or student ID code often results in items being returned to the sender.
- Write the Full Legal Name: Use the exact name the student registered with housing services or on their student ID card. Avoid nicknames.
- Include Specific Unit or Room Data: Add the room number, apartment identifier, or mail stop code clearly on the second address line.
- Verify the Street and ZIP: Match the physical building address with its correct zip code (90089 for central campus/Village, 90007 for North University Park).
- Skip Personal Phone Numbers: Couriers like FedEx and UPS prefer email notifications over phone calls, so include the student's active university email address on the shipping label instead of a phone number when possible.
Frequently Asked Questions
Can I use 90007 for all mail sent to USC?
No. While 90007 covers the surrounding neighborhood and certain university apartments, central campus buildings and the USC Village strictly require 90089. Using the wrong zip code slows down sorting.
Where should I send financial aid documents?
Official financial aid paperwork typically goes to the USC Financial Aid Office at 700 Childs Way, JHH 325, Los Angeles, CA 90089-0914. Always check department instructions online before mailing confidential forms.
What happens if I misspell a building name on a package?
If you include the correct street address, recipient name, and accurate zip code, campus mail services can usually route the item internally based on the student's ID or housing database records.
Is the Washington, D.C. center covered by these codes?
No. The USC Capital Program and Center in Washington, D.C., operates at a separate location on Massachusetts Avenue with its own local D.C. zip code.
