Manhattan Beach ZIP Coverage at a Glance
For ordinary street delivery, the verified Manhattan Beach ZIP is 90266. The official facility record places the Manhattan Beach Post Office at 1007 N Sepulveda Boulevard and identifies its ZIP as 90266-9998. That makes 90266 the sound starting point for a Manhattan Beach ZIP code directory, while USPS address lookup remains the authority for a particular delivery point. A city name in a mailing label is useful evidence, but it is not a legal boundary survey.
| ZIP | Areas covered | Post office | Notes |
|---|---|---|---|
| 90266 | Manhattan Beach, including downtown, the beach and Strand, North Manhattan Beach and El Porto, inland residential areas, and Manhattan Village | Manhattan Beach Post Office, 1007 N Sepulveda Blvd, Manhattan Beach, CA 90266-9998 | Primary and only verified general-delivery ZIP for the city; verify each address with USPS |
| 90267 | PO-box or legacy Manhattan Beach association reported by secondary sources | No current Manhattan Beach facility or city-serving coverage was verified | Do not treat it as a current street ZIP without USPS confirmation |
The table has one confirmed general-delivery row and one caution row. No official source verified a ZIP split or realignment year. Treat 90267 references as unverified, not as a citywide resident list.
Manhattan Beach 90266 and 90267
90266 is the only verified general-delivery ZIP assigned to the city in the local research. It reaches the compact coastal area from the Strand and downtown through North Manhattan Beach and El Porto, inland neighborhoods, and Manhattan Village. It does not follow every social or historical neighborhood label. El Porto, for example, has a separate past identity even though current mail routing can use the same city ZIP.
Myth. A ZIP list is not proof that every number on it still serves a city. The 90267 caution matters because secondary references connect that number with Manhattan Beach, but no current USPS facility or coverage page was verified for a general street-delivery role. Use USPS by address for the exact delivery point, and keep the unverified number out of a ZIP code directory unless the postal result confirms it.
For a visual check of the facility behind the confirmed ZIP, use the USPS location page for Manhattan Beach.
The location image anchors 90266 to the named post office. It does not turn the facility address into a city-limit map, so the municipal check still belongs with Manhattan Beach GIS.
Verify a Manhattan Beach ZIP
Start with the full street address, not a name and ZIP alone. The USPS ZIP Code Lookup by address offers By Address, By City and State, and Cities by ZIP Code modes. For a resident or family-history question, By Address is the useful mode because it tests the actual delivery point. Enter the street line, Manhattan Beach, and California, then save the returned city and ZIP exactly as shown.
Next, carry the standardized street line into the Los Angeles County Assessor Portal. The public search begins with AIN or address, while the parcel map supplies context. It is a bridge from postal geography to a legal parcel, not a ZIP-wide resident search. Record the AIN, situs, legal description, and map position before trying other sources.
USPS can change delivery rules, while a legal description can outlast a street name. If the postal city and GIS jurisdiction differ, investigate the mismatch.
For the source screen, open the USPS address lookup interface.
The lookup image shows why a five-digit code should be checked against the street line. A ZIP result narrows delivery geography; it does not identify the people connected to the address.
Manhattan Beach ZIP Search Fields
The clearest official people-oriented ZIP filter found in the research is California's Controller unclaimed-property search. It accepts a name or Property ID and offers optional City and ZIP Code narrowing. Use Manhattan Beach and 90266 only after a name search is justified. A matching reported city or ZIP is a lead about property reporting, not proof of a present address or residence.
| Field | Type | Required | Notes |
|---|---|---|---|
| Last or Business Name | Text | One of this or Property ID | Exact matches appear first; similar names may follow |
| First Name | Text | No | Narrows an individual search |
| City | Text | No | Manhattan Beach can reduce same-name results |
| ZIP Code | Text | No | 90266 is the useful verified local filter |
| Property ID | Text | Alternative required key | Enter it alone when known |
| Search | Button | Action | Runs the query |
Results can show a reported owner name, city or ZIP fragment, reporting holder, property category, and Property ID. Select Claim only if the record belongs to the person making the claim and follow the official proof process. Search is free, but the result is not an occupancy record.
Insider tip. The Assessor Portal does not document an unrestricted ZIP-wide owner search, and California My Voter Status authenticates a person's own record. Neither should be described as a public ZIP resident roster. Use the California unclaimed-property search for its stated fields, then verify any address with the source custodian.
Manhattan Beach ZIP Boundaries and City Lines
A ZIP Code is a USPS routing geography. Manhattan Beach city limits are a municipal boundary maintained through city and county mapping. The two systems serve different functions. A 90266 result can point to a mail route without proving municipal jurisdiction, and a city boundary check cannot replace USPS validation of a deliverable line.
Use the Manhattan Beach Interactive Mapping launch page after accepting its disclaimer. Compare the parcel location with the city edge, then reconcile the result with the Assessor's situs and AIN. No official local assessor, voter self-lookup, or permit portal was verified as allowing an unrestricted ZIP-wide resident result.
- ZIP versus ZIP+4
- A five-digit ZIP routes mail to a broad delivery area. ZIP+4 adds a delivery segment, not a parcel boundary or a list of residents.
- PO-box ZIP
- A code used for post-office boxes may not describe ordinary street delivery throughout the same area.
- Unique ZIP
- A code assigned to one high-volume organization or government destination is not a general neighborhood roll.
- Carrier route
- A postal delivery sequence inside a ZIP helps sort mail but does not define a city, school, parcel, or voting boundary.
Manhattan Beach ZIP and Parcel Keys
Four address terms often sit beside a ZIP but point to different records. The Assessor begins with an address or AIN and returns parcel facts. The recorder's real-estate index uses party names and recording years, not an address or ZIP. A tax mailing destination may differ from the physical site. Use the right key for the right custodian.
| Record key | What it identifies | Important limit |
|---|---|---|
| Situs | Physical parcel location | Does not list every person connected with the parcel |
| Mailing address | Where an agency sends correspondence | May be a PO box, office, trustee, or another city |
| Legal description | Land identity such as lot, block, tract, or recorded description | Can outlast a street label or postal city |
| AIN | Los Angeles County parcel identifier | Identifies an assessment parcel, not a household |
| ZIP | USPS delivery routing | Not a deed parcel, city limit, precinct, or ZCTA population count |
The Assessor's public web entry does not offer an unrestricted owner-name or mailing-address search. It is safer to describe the portal as an address and AIN tool. Public assessment records, where available through lawful service channels, still need a separate check against the situs and legal description.
For the parcel side of the ZIP code directory, use the Los Angeles County Assessor Portal and preserve the exact AIN format returned there.
Manhattan Beach, El Porto, and Old Streets
Manhattan Beach has a compact boundary but a layered address history. The city incorporated in 1912, added “Beach” to its name in 1927, and developed through beach lots, inland subdivisions, and later corridors. El Porto was a separate northern community before annexation. Older directories, newspapers, and deeds may therefore use El Porto, North Manhattan Beach, a subdivision name, or a postal community that differs from a current search label.
Sepulveda Boulevard was formerly Camino Real, and paving was completed in April 1931. Railroad Drive became the Valley Drive and Ardmore Avenue corridor. The 1923 map already shows much of the street pattern west of Sepulveda, making it a useful bridge for older address work. Search both the current and former road names before deciding that a household has vanished.
The Manhattan Beach map gallery supplies current street-index and detail-map links. Pair its modern labels with legal descriptions, old newspaper wording, and the El Porto name. A ZIP can stay stable while the words used by a directory or deed change.
Manhattan Beach Address Changes and ZIP
When the municipal address itself needs to be added, changed, or removed, the current formal path is the City Planning and Community Development Change of Address application. Reach that process through Manhattan Beach Community Development. A change in the street label does not erase the county AIN or the recorded legal description, so retain those older keys in the research notes.
A clean address correction follows a short sequence:
- Run the full street line through USPS and save the returned city and ZIP.
- Check the same location in city GIS and the Assessor Portal, recording the AIN and situs.
- Use the city address application when the municipal address record needs a formal change.
- Search older records with the former road, El Porto, subdivision, and legal-description terms.
This process keeps a corrected mailing label from being mistaken for a new parcel. It also helps connect a modern ZIP code directory entry to older maps and county records without claiming that the postal system controls land identity.
Manhattan Beach Counts Are Not ZIP Counts
Census QuickFacts reports Manhattan Beach as a city geography, not as a 90266 population file. The city had 35,506 residents in 2020 and an estimated 33,122 on July 1, 2025. Those figures describe the municipality, not every address using one postal boundary.
ZIP Code Tabulation Areas are statistical approximations built from postal patterns. They can differ from a city, parcel jurisdiction, or neighborhood name. Use the city total for civic context, then use USPS for an address and GIS for the city line. The compact 3.93-square-mile city still contains varied beach, downtown, El Porto, east-side, and commercial contexts, so a same-name result needs more than a ZIP match.
The official Census QuickFacts table for Manhattan Beach is the source for those city-level figures.
The QuickFacts image reinforces the geography rule: a city statistic is not a count of every address that happens to use the same ZIP.
From ZIP to a Manhattan Beach Street
A ZIP is a first narrowing step. Once USPS confirms an address, move to the city map and county parcel record. Do not infer a current resident from a tax parcel, unclaimed-property result, court filing, or historical directory alone.
For street-level work, the Manhattan Beach by-street address directory follows the parcel, AIN, GIS layers, city permits, and recorder limits in a separate address workflow. That keeps the ZIP code directory focused on postal geography instead of turning one ZIP into an unsupported list of people.
Lawful personal research can use these sources for family history, reconnecting with someone from the past, property curiosity, and civic records. Keep private household details out of a public search, respect protected-address programs, and never use a ZIP result to stalk, harass, or track a living person.
