Calabasas ZIP Code Coverage
Two ZIP codes are tied to the Calabasas postal identity in the current research. They do not form a clean outline of the incorporated city. One is the main street-delivery code, while the other is an auxiliary or post-office-associated layer. USPS groups both under the Calabasas 91302 labeling line, so the ZIP code directory must be read with the address and the parcel jurisdiction.
| ZIP | Areas Covered | Post Office | Notes |
|---|---|---|---|
| 91302 | Principal Calabasas street-delivery ZIP; also reaches nearby Los Angeles County communities and addresses outside the city | Calabasas-area USPS retail and delivery facilities; verify the station by address | Postal city does not prove incorporation; dominant city ZIP |
| 91372 | Auxiliary or PO-box-associated Calabasas ZIP | Calabasas Post Office | USPS groups it with 91302; official material does not conclusively call it PO-box-only |
The research does not support treating 91372 as a fully separate street neighborhood or claiming that every 91302 address lies inside the city. USPS address lookup is the final check for a particular deliverable address. Census ZCTA data can help with statistics, but a ZCTA is an approximation rather than a USPS ZIP boundary.
Calabasas ZIP 91302 Geography
91302 is the principal street-delivery ZIP associated with Calabasas, but its postal reach extends beyond the incorporated city. The research places the city beside unincorporated Santa Monica Mountains territory, Hidden Hills, Agoura Hills, Malibu and Los Angeles communities. A Calabasas postal line can therefore describe a nearby community or county island without proving city jurisdiction.
The official Calabasas Post Office is at 4774 Park Granada, Suite 10, Calabasas, CA 91302-9998, with phone number (818) 591-1790. Research lists weekday hours of 9-5 and Saturday hours of 9-2, with PO Box Online and no passport service. These are facility details, not a promise that every 91302 address is served from one counter. Use the current USPS location and address lookup for a live check.
For parcel research, keep three labels apart: the postal city on an envelope, the situs city tied to the physical parcel and the legal jurisdiction that controls planning or records. The county Assessor map is the stable starting point when the ZIP points to a broad area.
Calabasas ZIP 91372 Layer
91372 is associated with the Calabasas Post Office and appears with 91302 in the current USPS DMM L012 labeling list under CALABASAS CA 91302. That supports calling it auxiliary or PO-box-associated. It does not support a stronger claim that every 91372 use is PO-box-only. A ZIP code directory should preserve that uncertainty rather than turn an old shorthand into a current boundary rule.
A 2009 Postal Bulletin shows historical regrouping among 91302, 91372 and 91399, but the current 2026 list omits 91399. The omitted code should not be presented as a current Calabasas ZIP. When an old letter, deed or directory uses a different postal line, compare the dated address with a tract map, AIN and USPS verification.
Mail geography can help find a record under an older community label, yet it cannot replace the recorder's legal description or the Assessor's parcel key.
Verify a Calabasas ZIP
USPS ZIP Code Lookup is the authority for one deliverable address. Enter the street address and compare the returned ZIP with the postal city. Do not use a ZIP-only search to infer a household. The county Assessor Portal accepts an address or AIN, while the voter tool requires a last name, birthdate, house number and ZIP. Neither portal gives a public ZIP-wide resident roll.
The USPS page for the Calabasas Post Office supplies the facility route, phone and hours recorded in the research. A station page can change, so verify service at the same time as the address. If a ZIP result conflicts with a city label, keep both facts and check the parcel jurisdiction rather than forcing one answer.
Calabasas Residents by ZIP Code
A Calabasas ZIP code search is a sequence of filters, not one master roll. Begin with the address and USPS result. Use the Assessor map to locate the parcel and AIN. Use voter verification only for a person who can supply the required identity fields and for an approved purpose. Then move to the street-level record chain when the question has narrowed to one road or parcel.
- Verify the exact address in USPS ZIP Code Lookup and note the postal city.
- Enter the address or AIN in the LA Assessor Portal and save the parcel facts.
- Use the voter self-check only when last name, birthdate, house number and ZIP are known.
- For a larger authorized election-data request, use the county form and state the permitted purpose.
- Once the ZIP narrows the area, use the Calabasas street directory for address-keyed work.
The county does not offer a ZIP-only resident list through the Assessor site. GIS map selection can approximate an area only when an authoritative ZIP layer is present. A ZIP is a mail-routing key, so it should narrow a search and never stand in for a verified occupant record.
Calabasas ZIP Search Fields
The fields below show why the main Calabasas portals answer different questions. The Assessor is address and AIN keyed. The voter form is person keyed and uses a ZIP as one part of self-verification. Neither field set creates a public directory of everyone receiving mail in a ZIP.
| Portal | Field or control | Required | What it does |
|---|---|---|---|
| LA Assessor | Search by AIN or Address | Yes | Finds a parcel by AIN or situs address |
| LA Assessor | Basic Search | Control | Primary address or AIN mode |
| LA Assessor | Legal Search | Control | Legal and parcel-oriented mode |
| LA Assessor | Map Search | Control | Pan, zoom and select parcels |
| Voter verification | Last Name | Yes | Alphabetic text |
| Voter verification | Birthdate | Yes | mm/dd/yyyy |
| Voter verification | House Number and Zip Code | Yes | Numbers only; all four identity fields submit together |
The Assessor parcel card can expose AIN, situs, use type, legal description, assessed land and improvement values, tax-rate area, building characteristics and map links. Its online owner name is deliberately absent. Keep any mailing address obtained through a lawful channel separate from situs.
Calabasas ZIP Voter Context
The county's December 30, 2025 official report listed 16,911 registered voters in Calabasas. The report was refreshed January 15, 2026, and gives a records-specific count, not the population of a ZIP. Its party totals were 7,382 Democratic, 4,484 Republican, 779 American Independent, 75 Green, 166 Libertarian, 49 Peace and Freedom, 83 unknown, 91 other and 3,802 no-party-preference.
Census QuickFacts for Calabasas is a separate demographic source. Its city estimates should not be substituted for the postal population or the county's dated registration count.
California's My Voter Status tool is a self-service status route, not a ZIP enumeration tool.
The state form shows the difference between checking one record and drawing a ZIP-wide list.
Bulk voter files cost $146 countywide, $54 for a precinct, district or city and $39 for an additional file. A contract and an authorized election, scholarly, journalistic, political or governmental purpose are required. Advertising, solicitation, sale, marketing, Internet posting and harassment are prohibited. That rule keeps a ZIP code directory from becoming a casual voter roll.
Calabasas ZIP and City Lines
ZIP boundaries route mail. City boundaries set municipal jurisdiction. In Calabasas those lines diverge because the principal ZIP reaches nearby county communities and an official county planning lighting-zone map places the 91302 mailing ZIP in unincorporated Cheeseboro Canyon, a county island bounded by Ventura County, Calabasas and Agoura Hills. A postal city in an address line is therefore not proof of incorporation.
Use the county Assessor map for incorporated parcels and GIS-NET for planning context outside the city. GIS-NET principally covers unincorporated county territory. Compare situs city, postal city, parcel jurisdiction and city boundary before sending a city-record request or treating an address as a Calabasas municipal record.
- ZIP versus ZIP+4
- A ZIP code routes mail to a broad delivery area; the extra four digits narrow a delivery segment or route.
- PO-box-associated ZIP
- A code used with post-office boxes or an auxiliary postal layer; the Calabasas research does not prove that 91372 is only this.
- Unique ZIP
- A code assigned to one organization, building or other defined delivery point rather than a broad street area.
- Carrier route
- A delivery path used by the Postal Service inside a ZIP, not a city boundary or a household roll.
Calabasas Canyon ZIP Mismatch
The city follows canyon roads, former ranch and subdivision tracts, and the US-101, Las Virgenes and Mulholland corridors rather than a simple rectangular grid. That geography makes the ZIP code directory most useful as a first cut. It cannot settle whether a parcel falls inside the incorporated city, an unincorporated mountain area, or a neighboring community.
Safe at Home adds a separate confidentiality layer. Eligible participants can use a substitute mailing address, but the program does not erase older public records. A private or federal entity may not be required to accept the substitute, and a deed's legal description can still identify a parcel. Do not treat a missing name, changed postal line or protected address as evidence that a resident moved.
California Safe at Home information explains the substitute-address program and its limits.
The Safe at Home resource belongs in a ZIP search because postal clues and protected address rules can overlap without revealing a household.
Calabasas ZIP Code Directory Notes
USPS did not yield a static official neighborhood-by-ZIP table in the research. Verify every particular address with USPS ZIP Code Lookup. Do not add 91301, 91364 or 90290 to a Calabasas list without address-level proof. Older directory entries, deeds and letters may use a community, ranch, telephone exchange or postal label that does not match the current city line.
Keep the keys separate. USPS verifies delivery. The Assessor supplies parcel facts and an AIN. RR/CC, elections, courts and city offices hold different records. A ZIP code narrows the search, but the custodian's record answers the question.
For family history, preserve the original postal line and the date beside the modern ZIP result. For a present-day address, save the USPS response date, parcel AIN and jurisdiction. Those small notes make a Calabasas ZIP code search easier to check when a canyon road, PO box or county island creates a mismatch.
