Winchester ZIP Code Directory Coverage
Winchester is an unincorporated Clark County town and Census-designated place, not an incorporated city. County mapping and official Assessor samples confirm a working set of six ZIP codes for Winchester parcels: 89102, 89104, 89109, 89119, 89121, and 89169. The table identifies a documented connection, not an assertion that every address in a ZIP is within Winchester. Postal labels can reach farther than the town and can use Las Vegas even where the parcel card says WINCHESTER.
| ZIP | Areas Covered | Post Office | Notes |
|---|---|---|---|
| 89102 | Central-Valley area with a confirmed Winchester parcel at 4522 Del Oro Dr | Garside Post Office, Las Vegas | Use USPS for the individual delivery point. |
| 89104 | County-map area with a confirmed Winchester parcel at 2605 S Eastern Ave | Huntridge Post Office, Las Vegas | The ZIP does not mark the Winchester boundary. |
| 89109 | Central-Valley and resort-adjacent geography with a Winchester parcel example | Nearby Paradise Valley facility serves central-Valley routing context | Routing and recognized last line need address-level confirmation. |
| 89119 | Winchester parcel area plus broader institutional and commercial geography | Paradise Valley or University Las Vegas facilities, address-dependent | Postal footprint extends beyond one neighborhood label. |
| 89121 | Winchester parcel and Community Center area | East Las Vegas Post Office; Desert Inn is also an 89121 facility | County ZIP population is not a Winchester population. |
| 89169 | County-map area with a confirmed Winchester parcel at 1355 Laguna Ave | USPS recognizes Las Vegas as the last line | Check current routing by address before relying on a facility label. |
The county ZIP map provides regional context, while USPS validates the delivery point. An official static table proving every Winchester CDP-to-ZIP intersection was not located, so edge addresses need the two-source check.
Winchester ZIP Code Directory Limits
The key local distinction is between legal town, postal city, and ZIP. A Clark County parcel can show City/Unincorporated Town: WINCHESTER while its postal line says Las Vegas. A ZIP is a postal delivery construct, not a legal town line. That is why a ZIP code directory can narrow a search area without resolving whether a property lies in the Winchester CDP. The Assessor's City/Town selector is a legal-boundary tool. Its address form has no visible ZIP field.
Use the Town field when the parcel's legal geography is known. If postal information is uncertain, search again without it and inspect the returned card. The physical situs address, mailing address, postal city, legal town, ZIP, and legal description should remain separate notes. They represent different parts of the same record trail.
Winchester ZIP Code USPS Check
Use USPS ZIP Code Lookup before attaching a postal code to a specific Winchester delivery address. USPS offers By Address, By City and State, and By ZIP modes. By Address is the more precise choice when the legal town and postal city conflict. By City and State can show ZIPs associated with a city label, while By ZIP returns recommended or recognized city names. USPS warns that a ZIP result does not confirm that a person or business is present at the address.
The USPS lookup interface provides the delivery-point modes used to check a Winchester address.
The USPS result should be saved as postal evidence only, then paired with an Assessor or GIS result for the parcel context.
Winchester ZIP Map Context
Clark County's Valley ZIP-boundary map labels 89102, 89104, 89109, 89119, 89121, and 89169 across the central Valley. It is useful for seeing nearby labels and the broad shape of postal geography. The map carries a disclaimer and is not an exact delivery-point authority. Use it to decide which area to test, not to publish a hard boundary for Winchester.
OpenWeb offers parcel selection, address and jurisdiction context, and related record links, but the observed public parcel panel has no ZIP-wide export field. Select a parcel from the map, record its APN, then confirm it in the Assessor. A ZIP-wide project must be parcel by parcel rather than a claim that the GIS returns a complete residents list.
Note: The county map narrows geography, but USPS remains the better source for the accepted ZIP at one delivery address.
Winchester ZIP Code Treasurer Search
The Clark County Treasurer Tax Statement is the clearest county portal with a captured ZIP or Postal field. It permits searches by parcel number, individual name, organization, situs address, mailing address, street address, optional city or state, ZIP or postal code, and as-of date. Use the situs or mailing toggle deliberately. A situs search concerns the physical parcel; a mailing search concerns the tax-correspondence address. Its output is a parcel tax statement, not a list of people in the ZIP.
The Treasurer advanced-search capture shows the separate address modes and ZIP field.
After a candidate parcel is found, use the APN to compare the Assessor card, OpenWeb context, and Recorder instrument trail.
Winchester ZIP Code Search Fields
A Winchester ZIP code directory search is a sequence, not a ZIP-wide resident export. The Treasurer accepts the ZIP field, but the Assessor does not. The county GIS gives map context rather than a public export, and voter service is credentialed rather than an unrestricted street directory. Start with a delivery confirmation, then use the county tools to identify individual parcels and their records.
| Portal field | Type | Required | Use and limit |
|---|---|---|---|
| Situs Address toggle | Search mode | Choose one mode | Tests the physical parcel address. |
| Mailing Address toggle | Search mode | Choose one mode | Tests the tax-correspondence address, not presence at the parcel. |
| Street Address | Text | Street number required in this form | Pairs an address with a selected search mode. |
| City, State/Province | Optional text | No | Useful where a Las Vegas postal label and Winchester legal town differ. |
| ZIP/Postal | Optional text | No | The local ZIP-capable filter captured in county research. |
| As Of Date | Date | No | Calculates projected penalties and interest for a limited period. |
- Confirm the delivery ZIP with USPS By Address.
- Search a known street or parcel in the Treasurer using the correct address mode.
- Open the resulting APN in the Assessor and OpenWeb, keeping postal and legal fields separate.
- Use the Recorder parcel index only when an instrument trail is needed.
Once the ZIP narrows to a named road, the Winchester street directory has the fuller address workflow.
Winchester ZIP Population Caveat
ZIP totals can make a small place look larger than it is. Census QuickFacts reports Winchester's 2020 population as 36,403, within about 4.4 square miles. Clark County's 2024 ZIP population table reports 68,514 for 89121 and 25,193 for 89169. Those figures describe their ZIP footprints, which extend beyond Winchester. They cannot be added, substituted for the town's Census figure, or used as a count of local residents.
That difference is a practical quality check. The county ZIP map and parcel examples establish a working search area. They do not create a population boundary, and a public parcel owner display is not a population record. Cite the date and source whenever a ZIP total is used for local context.
Winchester ZIP Historical Addresses
Modern ZIPs should not be pasted onto a much older Winchester address. UNLV Special Collections has regional-history files for Las Vegas streets from 1913 through 1971 and street names from 1930 through 1968. The records do not establish a Winchester-wide renumbering event, but they offer a way to test an old spelling, street type, direction, or number. Pair a dated directory or newspaper address with the parcel's legal description or plat before deciding it is the same location.
Clark County was created in 1909 from Lincoln County, and historical records may use Las Vegas, Paradise, a precinct, subdivision, or postal city instead of Winchester. The Recorder's online Official Records index begins in 1988, while county microfilm reaches back to 1909. A past address that fails online may need a Recorder office request, microfilm, a library collection, UNLV, Nevada State Museum, Nevada Historical Society, or State Archives research.
Winchester ZIP Boundary Terms
These terms keep a ZIP code directory result from being overstated. A legal description refers to the lot, block, subdivision, or other recorded land description. It is often steadier than a street number when addresses change. A carrier route is a USPS delivery sequence, not a neighborhood boundary or a list of people.
- ZIP code
- A postal-delivery area used to route mail. It does not define the Winchester town or CDP boundary.
- ZIP+4
- An added four digits that refine delivery routing for a more specific segment, such as part of a block or a building.
- PO Box ZIP
- A ZIP used for post-office boxes. It is not evidence that a box holder is present at a physical parcel.
- Unique ZIP
- A ZIP associated with one institution or high-volume recipient. Research did not establish a unique Winchester ZIP in the confirmed working set.
- Carrier route
- A mail-delivery grouping. It is useful to USPS operations but not a legal town line or a resident roll.
