Valley Stream ZIP Code Areas
Postal geography and Village geography overlap, but neither one replaces the other. USPS assigns ZIP codes for delivery. Nassau County records place land through a Village field and a Section-Block-Lot number, often called an SBL. A tax roll, deed request, or Village record question needs that second level of checking. The ZIP is still useful because it helps normalize the address that will be entered into the official property tools.
| ZIP | Area or relation | Post-office context | Use it for |
|---|---|---|---|
| 11580 | Standard Valley Stream postal label | Valley Stream Post Office | Delivery check, never a legal boundary by itself. |
| 11581 | South Valley Stream label with Village and non-Village parcels | Confirm each address | Use the LRV Village field and SBL. |
| 11582 | Valley Stream-associated special ZIP in USPS material | Live USPS confirmation needed | Check the current classification before assuming delivery type. |
The research did not verify 11583 as a current Valley Stream ZIP. It should not be added merely because another source pairs it with the postal city.
Check a Valley Stream ZIP Address
USPS ZIP Code Lookup is the official first stop for delivery formatting. Its address form accepts an optional company, street, optional apartment, city, state, and ZIP. City/state and ZIP lookup modes are also provided. USPS says its result does not confirm that a person or company is actually located at an address. Treat the returned label as postal information, not proof of a household.
The official USPS screen provides the address and ZIP form used for Valley Stream postal checks.
After the postal check, the County tool supplies the parcel evidence that mail routing cannot provide.
- Enter the full known address in USPS and retain the returned ZIP format.
- Use that address in the Nassau Land Records Viewer.
- Save the Village, town, and SBL fields shown for the parcel.
- Use the SBL only when the next record is a tax, map, or deed question.
Valley Stream 11581 Boundary Check
ZIP 11581 is a specific local boundary trap. The research found an official County parcel page for 111 South Drive, a South Valley Stream 11581 address, that identifies an Incorporated Village parcel. It also found 697 Van Dam Street, another 11581 address, with Village shown as N/A in the Town of Hempstead. Those records are not evidence about residents. They demonstrate why a ZIP code cannot answer a Village-jurisdiction question.
Use the Land Records Viewer as the deciding record for parcel placement. Its public address search accepts house number, street name, town, and ZIP, or an already known SBL. The street field should omit a directional prefix and a suffix such as Avenue or Road. A CAPTCHA applies to unregistered public use, and the site presents an account option.
Postal versus parcel. USPS supplies a delivery label. The Nassau Land Records Viewer supplies the Village field, parcel placement, and tax-map context.
Valley Stream ZIP Code Fields
LRV includes a ZIP field, but it is not a ZIP-wide people finder. It is an address and parcel tool. Enter a known address, inspect the returned record, and keep the source date with any notes. The portal advertises assessment-roll data, district information, tax maps, property photos, past taxes and rates, exemptions, comparable sales, and a GIS link. It does not make a public owner-name search available from the inspected landing page.
| Field | Role in a ZIP check |
|---|---|
| House Number | Begins the address lookup. |
| Name of Street | Enter without direction or street-type suffix. |
| Town | Helps narrow similarly named streets. |
| ZIP | Supports an address-specific query. |
| Section, Block, Lot | Connects the address to a County parcel. |
A property owner, recorded party, or mailing address can differ from the physical property address. A ZIP-based result cannot settle that distinction.
Valley Stream ZIP Code Terms
Postal language and property language should stay separate while records are compared. The distinction prevents an old address lead from becoming a mistaken current-location claim.
- ZIP Code
- A USPS delivery-routing label, not a municipal boundary.
- ZIP+4
- An added delivery segment that does not change the base ZIP jurisdiction.
- PO-box ZIP
- A special postal label that does not prove street delivery.
- SBL
- Section, Block, and Lot, the County identifier for a parcel.
- Situs address
- The physical property address, which can differ from an owner mailing address.
Once a ZIP narrows an address to a street, the Valley Stream street directory has the address-keyed parcel and deed method. It does not turn a ZIP into a resident list.
Valley Stream Postal Office Details
The Valley Stream Post Office is listed at 111 South Franklin Avenue, Valley Stream, NY 11580-6136, with published retail hours of Monday through Friday, 9 a.m. to 5 p.m., Saturday, 9 a.m. to 1 p.m., and Sunday closed. Confirm service hours before visiting. The postal page helps with delivery-service questions; it is not a source for a person search.
The post-office detail screen is included for the local ZIP code directory.
It supports the postal side of an address question, while County parcel records provide the legal location context.
Historic Valley Stream ZIP Clues
Many historical addresses predate ZIP codes. Nassau County formed in 1899, and VSHS says the 1870 Litchfield property plan was filed in Queens County. Pre-1899 map or property research may therefore need a Queens-era repository. VSHS also identifies Wheeler Avenue as the former Chapel Avenue and connects historical Roosevelt and Second Street material with Legion Place. Preserve each historic and modern form in a record search.
The same VSHS material says 1930 was the first census to show actual house number as well as street name in this setting. A census entry can help bridge a dated address trail. It cannot certify a modern mailing label or parcel boundary.
Note: Compare every street spelling and address number with the date of the underlying map, census, directory, or tax record.
Valley Stream ZIP Parcel Context
The Village Tax and Assessment Department provides a second address-based record layer after LRV. Its research description says the office maintains about 11,000 parcel records and publishes assessment rolls, tax rolls, bills, ownership, exemption, assessed-value, and physical-property-change information. The 2025 Village roll can show a parcel or grid identifier, owner name, owner mailing address, deed book and page, property description and class, values, exemptions, and tax fields. Its final assessment roll is filed April 1.
Those fields give a dated property snapshot. They do not produce a list of people in a ZIP code. An owner can use a separate mailing address, and a named party on an older deed may have sold the property years ago. Keep the tax-roll date beside the record, and use the address and SBL rather than a ZIP alone when a County or Village office must identify the parcel. When a field seems inconsistent, ask the office that maintains that field about its correction procedure instead of copying an unverified version into another search.
For a recorded instrument, the Nassau County Clerk’s land-record index is the next channel. The index is free to search, but document images and certified copies have separate access routes. It is more precise than treating a postal label as an ownership result.
Valley Stream ZIP Results Need Dates
Address records change over time. The County Clerk identifies land archives dating to the 1899 County era, while its electronic database began in 1992 and the online system describes images from February 22, 1994 forward. That timeline means an absent online image is not proof that a deed was never recorded. A researcher with the last known document, SBL, date, or book-page reference can continue at the County Clerk’s Mineola counter and Map Room.
Historic delivery labels need the same caution. VSHS supplies 1870 and 1871 Litchfield maps, local streetscape material, and a referenced July 1918 Sanborn image, but full Sanborn coverage was not confirmed. Library and Historical Society research visits are the documented way to ask for an address-specific map, newspaper, or directory check. Search results should preserve the year, spelling, and source instead of treating an old address as a current postal fact.
Note: A complete ZIP code narrows a delivery area, while an SBL and recorded date keep the property trail tied to a particular parcel and era.
Limits of Valley Stream ZIP Search
No reviewed County system offers a verified public search for all residents within a ZIP. USPS is a delivery verifier. LRV resolves a specific parcel. The Village tax roll provides dated property context, but its owner and mailing fields are not proof of a current occupant. New York’s voter self-service tool is for a voter’s own registration and poll-site information, not a public ZIP roster.
Keep any search tied to a specific address, document, parcel, or historical question. Protected voter records, Address Confidentiality Program locations, DMV data, utility accounts, and household details are not substitutes. Use records for lawful personal research only, never to stalk, harass, or harm another person. When information conflicts, preserve the source and date, then request direction from the office that holds the underlying record for that exact document.
