La Jolla, CA Zip Codes: Complete List, Map Boundaries, and Local Data for 2026

The median sale price for homes in La Jolla, CA sits at roughly $2,389,846 - which tells you right away this isn't a casual market, particularly for those buying La Jolla oceanfront real estate. With 175 homes currently available, most buyers find they need to narrow their search by postal boundary just to make the inventory manageable. Knowing which zip code you're working in also keeps your utility setups and closing documents clean from the start.

What surprises a lot of people is that a community this size doesn't run on a single zip code. The mailing system here is a little more layered than you'd expect - residential zones, university designations, PO Box codes. Once you understand how the boundaries work, it saves you real time, whether you're tracking listings or just trying to format a delivery address correctly.

The Primary Zip Code for La Jolla, CA

If you're buying a home here, 92037 is the number you'll use. It covers the vast majority of single-family homes, townhouses, and commercial businesses throughout the community - this is the standard residential zip code for La Jolla, CA, full stop.

That said, the United States Postal Service designates four additional zip codes for the area, bringing the total to five. Zip codes 92038 and 92039 are reserved exclusively for Post Office Box addresses. The remaining two - 92092 and 92093 - are assigned specifically to the University of California, San Diego (UC San Diego) campus and its immediate related facilities. The university handles a massive volume of daily mail, so those unique codes exist to keep campus deliveries off the standard 92037 residential routes. If you're focused on traditional housing inventory, you won't deal with any of the other four.

Breaking Down the La Jolla Zip Code Map

The 92037 boundary covers a population of approximately 41,260 residents, stretching along the coastline and moving inland to capture almost all of the private housing stock. The separate university zip codes - 92092 and 92093 - carve out specific sections in the northern part of the community where UC San Diego operates.

What you won't find on a La Jolla zip code map is a patchwork of different residential codes. The community's distinct sub-neighborhoods all share 92037, so neighborhood names do the work that multiple postal codes might do elsewhere.

Neighborhoods Within the Primary Boundary

The list of sub-neighborhoods inside 92037 is longer than most people realize. Bird Rock, La Jolla Shores, La Jolla Village (most locals just call it the Village), and La Jolla Farms are the names you'll hear most often. But the same code also covers Muirlands and Muirlands West, Upper and Lower Hermosa, La Jolla Heights, La Jolla Alta, and La Jolla Mesa.

Hidden Valley, Soledad South, Mount Soledad, and La Jolla Country Club round out the list. Homes here have been averaging 32 days on market recently, so knowing these neighborhood names specifically - not just the zip - is what lets you move quickly when the right property surfaces.

Famous Landmarks by Location

The 92037 boundary includes La Jolla Cove, the Children's Pool, and Windansea Beach with its historic surf shack. Mount Soledad National Veterans Memorial also falls within the primary residential postal boundaries.

UC San Diego's Geisel Library sits within the university zip codes, 92092 and 92093. Other well-known spots - the Salk Institute, Scripps Pier, the Birch Aquarium, Sunny Jim's Sea Cave, and Torrey Pines State Natural Reserve - are spread across the northern coastal sections of the community.

County and Regional Context

La Jolla sits entirely within San Diego County, operating as a distinct community within the broader San Diego metropolitan area. It's a question buyers relocating from out of state ask more than you'd think: what county is La Jolla, CA in? The answer matters because it determines your property tax jurisdiction and which county-level services apply to your address.

All real estate transactions here are processed through the San Diego County Assessor and Recorder offices. The local market has seen 135 homes sold recently across the community, and every one of those deals ran through the same county-wide recording procedures.

Finding Your 9-Digit Zip and Local Area Code

La Jolla's primary telephone area code is 858. The 619 area code also serves as an overlay for the broader San Diego area, so new residents can end up with a 619 number even if they're living squarely within the 858 geographic boundaries.

For mailing, the United States Postal Service uses a ZIP+4 system that tacks four extra digits onto the standard five-digit code. Those additional digits identify a specific delivery route, city block, or even a single office building. To find the full 9-digit zip code for a La Jolla, CA address, use the official USPS lookup tool and enter the specific street number and name. A home on Girard Avenue, for example, would use 92037-xxxx, with the final four digits varying depending on which side of the street the house is on.

Real Estate and Population Data

The 92037 residential zip code holds approximately 41,260 people. The two university zip codes are considerably smaller - 92092 has about 5,251 residents and 92093 around 5,076. The PO Box codes, 92038 and 92039, carry a recorded population of zero.

The market data worth keeping in mind: roughly 4 months of housing supply is currently available, homes are selling at about 97.5% of list price, and nearly 17.5% of recent sales closed above asking. Those numbers are just as relevant to your preparation as the postal boundaries are.
