Union City ZIP Code Directory Coverage

Union City has one verified primary postal ZIP, 07087. Nearby codes belong to other Hudson County municipalities or to Jersey City, the county seat. A close postal label can be useful for checking a boundary or locating a county office, but it should not be folded into a Union City record search without an address-level result. The confirmed local post office and stations use 07087 suffixes, while the nearby rows below identify surrounding postal geography rather than extra Union City delivery coverage.

The table is deliberately conservative. The research did not locate a local USPS boundary shapefile, a verified postal split history, a Union City PO-box-only ZIP, or a unique-institution ZIP. A postal code is a delivery construct, so the official USPS result for the full address is stronger than a broad list or a map assumption.

Verify Union City ZIP Codes With USPS

Start with the USPS address-to-ZIP lookup. Enter the street number and street name, then provide Union City and New Jersey. Compare the returned postal city, ZIP, and ZIP+4 with the municipality and situs found in the property record. Save the date of the postal result when it is being used to resolve an address conflict, because delivery information can change over time.

1. Enter the full street address in the USPS by-address tool, including the number and street name.
2. Compare the returned postal result with the Union City municipal field. Do not replace the municipal label with the postal city.
3. Locate the same property in the tax or state parcel route and record the situs plus block and lot.
4. If a deed uses a legal description, compare that description and municipality with the parcel key before joining it to the postal result.
5. Use a neighboring code only as a boundary check. Search the specific address again if the result is uncertain.

The USPS ZIP lookup source below is the official tool for checking a mailing address against a current delivery result.

USPS ZIP+4 and carrier-route details support delivery. They are not legal parcel lines, neighborhood borders, or a public list of people at an address. For a named street trail after the postal check, use the Union City street directory and its parcel-to-deed workflow.

Note: A matching postal result confirms a delivery label, while the tax parcel and recorded instrument answer different property questions.

Union City ZIP Code Parcel Fields

A local ZIP code directory cannot turn the property route into a verified ZIP-wide people search. The Union City Tax Department links to assessment and tax-postcard tools, reassessment material, appeals, and a 200-foot property-owner-list request. The linked assessment route commonly uses district code 0910. The research did not capture the live vendor's complete field list, and the state Property Explorer is documented for address, county, municipality, block, and lot rather than a ZIP-wide resident browse.

The Union City tax-search route below is the source captured for district 0910. Its interactive fields should be checked in the live service before relying on an interface detail that was not exposed in the research.

Use the property data to follow one address, not to infer an entire postal area's current households. State parcel material also cautions that owner names may be redacted under Daniel's Law and that assessor data reflects annual local filings, which may lag a later change.

Union City ZIP Code Post Office

The verified local postal counter is the Union City Post Office at 301 30th Street, Union City, NJ 07087-9998. USPS lists retail hours of Monday through Friday, 10:00 a.m. to 5:00 p.m., and Saturday, 10:00 a.m. to 2:00 p.m. PO Box access is listed Monday through Friday, 6:00 a.m. to 5:00 p.m., and Saturday, 6:00 a.m. to 2:00 p.m. Confirm hours with USPS before visiting.

The USPS Union City Post Office source below also identifies the local location and access information used for the primary postal ZIP.

USPS also lists the Bergenline station at 2100 Bergenline Avenue and the Forty Fifth Street station at 4535 Bergenline Avenue, Suite A, both with 07087-999x suffixes. A post-office address or station suffix helps confirm postal service context. It does not replace the municipality, parcel, or recorded legal-description fields used by local records offices.

Nearby ZIP Codes Around Union City

The close Hudson County codes have different research roles. Weehawken uses 07086, West New York uses 07093, and North Bergen uses 07047. Hoboken's 07030 and Secaucus's 07094 are also nearby labels. Jersey City uses 07306 and 07307, which can appear in a Union City research trail because the Hudson County Register, county election offices, county courts, and county GIS are based in Jersey City.

That county-versus-city geography is easy to miss. A county office's Jersey City mailing address does not make a Union City parcel a Jersey City parcel. Keep the municipality field, parcel block and lot, and full postal result in the same notes. In a city of about 1.29 square miles with a dense parcel map, a precise property key is more useful than a nearby postal label alone.

Union City ZIP Code and City Lines

Postal geography and government geography overlap without being the same thing. The municipal tax and assessor route holds local parcel context. Hudson County GIS maps county parcels. USPS verifies a delivery ZIP and postal city. The Register's Jersey City office may hold a deed for a Union City property. Treat each system's label as evidence for its own purpose, then compare them rather than declaring a boundary from any one of them.

The research found no verified statement that 07087 follows every city limit, nor a verified adjacent code serving a Union City street. Use the full-address USPS response for delivery, the Union City municipality value for local property work, and the legal description for a deed. A mailing address can sit outside Union City without changing the parcel situs.

ZIP

A USPS delivery-routing code, not a city-limit survey or parcel boundary.

ZIP+4

An added delivery detail used by USPS to sort mail more precisely within a ZIP area.

PO Box ZIP

A postal code associated with box service; the research did not identify a separate Union City PO-box-only code.

Unique ZIP

A code assigned to a single organization or address. No verified Union City example was located in the reviewed sources.

Carrier route

A USPS delivery grouping that supports mail handling and does not establish a legal property boundary.

Older Union City Postal Search Terms

Postal research becomes more reliable when historical municipality labels travel with the address. Before the 1925 consolidation, relevant records may use Union Hill, Town of Union, or West Hoboken instead of Union City. The official city history and a state municipal-history table give different 1925 effective dates, so preserve the source-specific date rather than treating it as one settled cutoff.

Older directories may use a prior city label or post-office convention. Search the street, house number, cross street, and former municipality term together, then compare the result with the Library of Congress Union City street-address directory holdings for 1946, 1954, and 1956 through 1958. The research did not find proof that an old postal code applies retroactively to an earlier directory entry.

Note: Historical names and the exact street address are stronger search aids than assuming a modern postal label belonged to an earlier record.

Limits of a Union City ZIP Code Directory

A ZIP code narrows delivery geography. It does not create a current resident roster, confirm an occupant, or reveal private utility, delivery, DMV, or protected-address data. The state voter lookup is person-specific and exact-name sensitive, not a neighborhood browse. Parcel and deed records can identify a property or recorded party, but they should not be used to guess a household from a postal label.

New Jersey's Address Confidentiality Program supplies an eligible participant with a substitute address, and Daniel's Law can require address suppression for protected people. A blank or redacted result can be a lawful privacy limit. Use only the minimum public information needed for a personal, family-history, property, estate, civic, or identity-confirmation question, then verify consequential details with the custodian.
