Finding the exact Cal Poly Pomona address and zip code matters whether you're mailing official documents, dropping off a prospective student, or setting up your GPS for a campus visit. California State Polytechnic University, Pomona is located at 3801 W. Temple Ave., Pomona, CA 91768. Because the campus spans over 1,400 acres across hilly terrain in Los Angeles County, relying on a single street address without understanding how mail delivery, parking structures, and building codes work can lead to frustrating delays.
Knowing the physical location is only half the battle. If you're shipping parcels to residence halls or department offices, formatting mistakes cause mail to sit in sorting rooms or return to sender. Let's break down everything you need to know about the campus location, mailing specifics, and getting around.
Cal Poly Pomona Location and Main Address
The primary administrative and campus-wide address for California Polytechnic State University, Pomona is:
- California Polytechnic State University, Pomona
- 3801 W. Temple Ave.
- Pomona, CA 91768
This address covers the main campus area situated near the intersection of the 10 and 57 freeways. While the mailing address uses a Pomona designation, the campus sits right on the border of several municipalities, including Walnut, Diamond Bar, and La Verne.
If you punch the main address into a mapping app like Google Maps, it usually drops you near the front of the campus or the CLA building area. However, because the campus is massive, you shouldn't use the generic main address if you're trying to visit a specific department, residence hall, or parking structure. Always check the individual college or building code before you start driving.
Zip Codes Surrounding the Campus
The primary zip code for the university is 91768. However, depending on where you are relative to the campus boundaries, neighboring postal codes come into play.
- 91768: Covers the main campus, university residence halls, and immediate surrounding areas in Pomona and Walnut.
- 91766: Covers downtown Pomona and southern sections of the city, located a few miles away from the university proper.
- 91750: Covers the city of La Verne directly north of the campus area.
- 91789: Covers the city of Walnut immediately west of the campus boundaries.
If you're filling out online forms or setting up utility accounts for off-campus housing near the university, double-check your exact street name. Mixing up 91768 and 91789 happens all the time because student apartments straddle the Pomona-Walnut municipal line.
How to Address Mail and Packages to Students
Mailing items to students living on campus requires a specific format to ensure the Bronco Bookstore or the university mail services department processes it correctly. Don't just slap a name and the main campus address on an envelope.
For students living in campus housing, mail must include the specific residence hall name and room number. The general format looks like this:
- Student Full Name
- Residence Hall Name and Room Number
- 3801 W. Temple Ave.
- Pomona, CA 91768
If you omit the specific residence hall or room number, package processing slows down significantly. The university handles thousands of pieces of mail daily, and incomplete recipient data leads to unclaimed parcels sitting in storage.
For academic departments or faculty offices, include the building number and department name:
- Faculty or Department Name
- Building Number, Room Number
- 3801 W. Temple Ave.
- Pomona, CA 91768
You can check building numbers on the official Cal Poly Pomona Directory before sending official paperwork or transcripts.
Navigating to Specific Campus Zones
Arriving at the main entrance on Temple Avenue gives you access to the core of the campus, but navigating internal roads requires patience. The campus features steep inclines, pedestrian zones, and distinct functional zones.
Parking and Permits
Visitors must purchase a parking permit immediately upon arrival. Parking Services operates automated pay stations in major lots and structures, including the Parking Structure 2 and the CLA Parking Structure.
- Don't park in designated employee or reserved stalls without the correct virtual permit registered to your license plate.
- Campus parking enforcement is active year-round, even during summer sessions and breaks.
- Daily permits cost a flat rate, and tickets for violations run significantly higher than a day pass.
Public Transit Access
If you aren't driving, public transit options connect the campus to the wider Los Angeles and Inland Empire regions.
- Foothill Transit operates several lines that stop directly on campus, connecting riders to nearby Metrolink stations.
- Metrolink trains run lines through the nearby Pomona North or Downtown Pomona stations, requiring a short bus connection to reach university grounds.
Common Mistakes to Avoid
People often make avoidable errors when dealing with university addresses and logistics. Keep these pitfalls in mind to save yourself time and hassle:
- Using the wrong city name: While the mailing address uses Pomona, parts of the student housing and surrounding infrastructure sit right on the edge of Walnut. Ensure your shipping provider accepts the address format without flagging delivery errors.
- Ignoring building numbers: Dropping a package at the main gate or mailing room without a building destination means it could take days to reach a department office.
- Trusting generic GPS pins: The main campus covers nearly 1,500 acres. If you're attending an event at the Rose Float lab or the Collins College of Hospitality Management, search for those specific landmarks rather than the general university address.
