Long Beach, CA ZIP Codes: The Full List, From a City That Isn't a County Seat

27 ZIP codes, one county, and a city bigger than most county seats

Los Angeles holds the title of seat for Los Angeles County; Long Beach never has, despite outgrowing plenty of actual county seats along the way. Wikipedia puts Long Beach's 2025 population at roughly 450,469, good for 44th nationally and 7th in California, and that same profile calls it the largest city in the state that isn't a county seat at all. GeoNames' postal-code dataset still ties Long Beach to that same county on paper: all 27 ZIP codes assigned to the city fall inside Los Angeles County, with no split the way some other cities on this site's lists have.

Three of those 27 codes, 90834, 90835, and 90899, returned no individual record when checked against zip-codes.com's lookup tool on August 22, 2026, unlike the other 24, which all resolve. The remaining 24 split by delivery type into 14 standard residential routes, 4 PO Box-only codes (90801, 90809, 90832, and 90853), and 6 codes zip-codes.com classifies "Unique," set aside for a single business, government office, or institution rather than a stretch of streets.

The county job Long Beach doesn't hand off

All 27 of those ZIP codes carry the same county on this site's records, Los Angeles, but Long Beach doesn't route every civic function through that county the way its neighbors do. The city's health department page states that Long Beach runs its own department, separate from the county; Berkeley's local news outlet, Berkeleyside, counts Long Beach among three California cities that do this, alongside Berkeley itself and Pasadena, though a fourth, the small industrial city of Vernon, also operates one, according to that city's government website. For a city whose ZIP codes all report to Los Angeles County on paper, that's one civic function Long Beach never outsourced.

The department the city describes runs more than 500 employees across nine locations on an annual budget near $117 million, according to that same city page, funded mostly through federal, state, and county pass-through dollars rather than city general funds alone.

A campus ZIP code with a population of 8

90840 carries California State University, Long Beach entirely by itself. zip-codes.com's records show a total population of 8 for that code, not a typo, since a single campus doesn't generate the kind of residential count a neighborhood-wide ZIP does, and the lookup service groups it with the handful of codes reserved for one organization instead of a stretch of streets, the category this article's table above labels "Unique."

Five more codes, 90842, 90844, 90846, 90847, and 90848, carry that same "Unique" label on zip-codes.com, but the lookup tool doesn't publish which single business or office each one serves, only that USPS treats each as a single mail recipient, not a stretch of addresses. 90822 sits close to that pattern without officially joining it: zip-codes.com classifies it "Standard," yet its total population comes back at 54, and the Department of Veterans Affairs' website lists that code as home to the VA Long Beach Healthcare System, including the Tibor Rubin VA Medical Center.

An area code inherited twice over

Long Beach dials on 562, a code this site's area-code records date to January 25, 1997, when it split off from 310. That earlier code, 310, is itself a split, carved out of 213 on November 2, 1991. This site's rundown of the 213 area code's overlay history covers that same chain of splits in more depth, including why a hip-hop group named itself after 213 years after Long Beach itself had already moved to 310.

Three codes, 90834, 90835, and 90899, returned no record on zip-codes.com as of August 22, 2026.

Does Long Beach have its own health department?

Yes. The city's health department page describes Long Beach as running its own department rather than relying on the county; Berkeleyside counts three cities that do this, Long Beach, Berkeley, and Pasadena, though a fourth, the industrial city of Vernon, also runs one. That's separate from the Los Angeles County health department that covers most other cities in the county.

What ZIP code is California State University, Long Beach?

90840. zip-codes.com classifies it "Unique," the tier reserved for a single institution rather than a residential route, and its own population count for that code comes back at 8.

What area code does Long Beach, CA use?

562, which split off from 310 on January 25, 1997. 310 itself had split from 213 on November 2, 1991, so Long Beach's current code is two splits removed from the area code that once covered all of central Los Angeles.
