Orange County, CA ZIP codes: a full list by city and region for 2026

by Power Real Estate Group

When you start looking at homes in Southern California, you'll notice quickly that mailing addresses don't always tell the whole story.

Key takeaway

Orange County has no single ZIP code, and the city printed on a mailing address doesn't always match the city or county that governs the home. Look up the ZIP by exact address, confirm the jurisdiction on the parcel, then filter by property type. Townhouses had the lowest median price per square foot countywide in the 30 days ending September 30, 2026. Condos are the alternative if negotiating room matters more than space.

Who this guide is for

You're looking up Orange County ZIP codes to place an address, compare areas, or set up a home search, and you need to know what a postal code does and doesn't tell you before relying on one.

How ZIP codes work in Orange County

A ZIP code is a mail route, not a boundary or a price tag. The property type you choose inside any ZIP sets the price band: the countywide median single-family home recently sold for roughly $1,447,008, versus about $714,350 for a condo, in the 30 days ending September 30, 2026.

The United States Postal Service draws these codes around delivery routes rather than city limits. Besides its incorporated cities, the county has several unincorporated communities managed directly by the County of Orange. The city name on a mailing address is the post office's name. It is not necessarily the government that sets the tax rate area, handles permits and policing, or draws school lines.

Before using an address in a search, confirm its exact ZIP with the USPS ZIP Code Lookup. Then check the parcel's city or unincorporated status and its tax rate area on the County Assessor or tax bill record, not the mailing address. The tax rate area, not the ZIP, sets which property tax rates apply. Confirm the school district with the district boundary lookup too, because a postal code doesn't determine school assignment.

North Orange County ZIP codes

North County mixes large cities with smaller towns along the Los Angeles and San Bernardino county lines. Anaheim, Fullerton, Orange and Garden Grove each span several ZIPs covering different neighborhoods. Anaheim Hills is not its own city. Homes there carry Anaheim ZIPs 92807 and 92808, so search for it as Anaheim.

Anaheim: 92801, 92802, 92804, 92805, 92806, 92807, 92808
Fullerton: 92831, 92832, 92833, 92835
Orange: 92865, 92866, 92867, 92868, 92869
Garden Grove: 92840, 92841, 92843, 92844, 92845
Yorba Linda: 92886, 92887
Brea: 92821, 92823
Placentia: 92870
Buena Park: 90620, 90621
Cypress: 90630
La Palma: 90623
Stanton: 90680
Los Alamitos: 90720

ZIPs here blur county and city lines. ZIP 90631 extends past the county line into La Habra Heights in Los Angeles County, so confirm the county on the preliminary title report for any address there. Rossmoor is an unincorporated area governed by the Orange County Board of Supervisors. It still gets mail through the Los Alamitos post office and shares the 90720 ZIP.

Central Orange County ZIP codes

Irvine has the most residential ZIPs of any central city, followed by Santa Ana. Tustin and Costa Mesa round out the core, with a wide variety of housing tracts. Newer Irvine villages may carry Mello-Roos special taxes, which show up as special assessments on the property tax bill.

Irvine: 92602, 92603, 92604, 92606, 92612, 92614, 92617, 92618, 92620
Santa Ana: 92701, 92703, 92704, 92705, 92706, 92707
Tustin: 92780, 92782
Costa Mesa: 92626, 92627
Fountain Valley: 92708
Westminster: 92683

A Santa Ana mailing address doesn't always mean the home is in Santa Ana. Part of 92705 covers North Tustin, an unincorporated community outside Tustin's city limits, and Santa Ana is the USPS mailing city for 92705. Two homes a block apart can carry the same postal city and land in different jurisdictions, with different tax rate areas and service providers. Midway City has its own ZIP, 92655, but it is an unincorporated community with no city government.

Coastal Orange County ZIP codes

The coastline runs from Seal Beach to San Clemente and includes some of the most expensive areas in the county. Several coastal addresses carry neighborhood postal names that aren't separate cities. Corona del Mar and Newport Coast are neighborhoods within the incorporated City of Newport Beach, and Sunset Beach is part of Huntington Beach.

Seal Beach: 90740
Huntington Beach: 92646, 92647, 92648, 92649, plus Sunset Beach 90742
Newport Beach: 92660, 92661, 92662, 92663, plus Newport Coast 92657 and Corona del Mar 92625
Laguna Beach: 92651
Dana Point: 92629
San Clemente: 92672, 92673

Those separate postal names cause missed listings. A search filtered strictly to "Newport Beach" can skip homes entered under Corona del Mar or Newport Coast, so search by the specific ZIP as well as by the city name.

South Orange County ZIP codes

South County is known for its master-planned communities in cities like Mission Viejo, Lake Forest, Laguna Niguel and Aliso Viejo. Some areas here have no city government, and only the parcel record shows it. Ladera Ranch is an unincorporated master-planned community managed by the County of Orange rather than its own city hall. Many newer South County neighborhoods also carry the same Mello-Roos special taxes as newer Irvine villages.

Mission Viejo: 92691, 92692
Lake Forest: 92630, 92610
Laguna Niguel: 92677
Aliso Viejo: 92656
Laguna Hills: 92653
Laguna Woods: 92637
Rancho Santa Margarita: 92688
San Juan Capistrano: 92675
Ladera Ranch and Rancho Mission Viejo: 92694
Trabuco Canyon and Coto de Caza: 92679

Laguna Woods Village, in 92637, is an age-restricted community under California Civil Code §51.3. At least one occupant of a household must be 55 or older, and other occupants must generally be at least 45, with limited exceptions. Confirm eligibility rules directly with the community before shortlisting that ZIP.

Searching for a home by ZIP code

Your property type determines your price band and your negotiating room far more than a postal code does. The figures below are countywide, not by ZIP.

Condos recently sat for a median 61 days on market with 4.0 months of supply, and only 13.4% sold above list price. That gives you real room to ask for repairs or credits during escrow. Single-family homes had 2.8 months of supply, with 29.6% selling above list. If you need a detached house, plan offers at or near asking price in tight ZIPs. Tactics for buying a home in Orange County shift based on these market speeds.

Townhouse prices dropped 3.8% year over year, yet townhouses still sold at 99.3% of list. The drop is already priced into list prices, so the saving comes from the lower asking price rather than from haggling. Power Real Estate Group can pull comparable sales for the specific ZIPs on your shortlist to help you structure an offer.

Countywide medians blur big differences between individual ZIPs, and condo and townhouse prices exclude monthly HOA dues. Ask for recent sales in the specific ZIP and the HOA's current dues before you compare areas.

How to narrow your ZIP code shortlist

If you have a specific address, start with the USPS lookup and the parcel record described in How ZIP codes work. If it matters whether a city or the County of Orange handles your permits, policing and tax rate area, read the catch at the end of each region section. Settle on property type before you compare ZIPs, using the section above. If you're open to more than one part of the county, scan the north, central, coastal and south sections for cities that fit, then open the linked area guide for each one you keep.

If you want the most interior space for your budget, start with townhouse listings in the ZIPs on your shortlist. Townhouses sold for a median $588 per square foot countywide. If you want room to negotiate on price, repairs or credits, start with condo listings. If you need a detached house, start with single-family listings.

If you want certainty about which government handles your taxes, permits and policing, start with the parcel record for any address in 90631, 90720, 92705, 92655, 92694 or 92679. These figures are countywide market data, not an appraisal or a recommendation for a specific home. Browse our best neighborhoods page and our current homes for sale to see live listings.
