Washington Township ZIP Code Coverage
Current local address evidence confirms two Washington Township delivery ZIP codes: 48094 and 48095. The official Michigan map also shows nearby 48065, 48096, and 48062, but those are map neighbors, not confirmed Washington Township coverage. A postal label is not a survey of township limits, so each specific address still needs a USPS check and a county parcel comparison.
| ZIP | Areas Covered | Post Office | Notes |
|---|---|---|---|
| 48094 | Township civic-center and core local-office address evidence | Washington, Michigan postal identity | Primary municipal ZIP in current local materials; exact boundary not located |
| 48095 | North/Van Dyke and 29 Mile local address examples | Washington, Michigan postal identity | Confirmed township examples; exact boundary not located |
| 48065 | Romeo on the official Michigan ZIP map | Romeo, Michigan | Nearby map ZIP only; township use not established |
| 48096 | Ray on the official Michigan ZIP map | Ray, Michigan | Nearby map ZIP only; township use not established |
| 48062 | Richmond on the official Michigan ZIP map | Richmond, Michigan | Nearby map ZIP only; not evidence of township delivery |
The table deliberately separates confirmed township examples from nearby postal areas. No exact boundary, population, PO-box-only ZIP, unique ZIP, or ZIP realignment history was located in the reviewed sources.
That distinction prevents a common error. A map can show a nearby Romeo, Ray, or Richmond ZIP without proving that a Washington Township parcel receives mail through it. The recorded local examples establish 48094 and 48095, but a full delivery address remains necessary for every new search. Use a Postal Service result to test delivery, not as evidence of a township line.
Washington Township ZIP Code USPS Check
USPS is the delivery authority for a full address. Its ZIP Lookup tool provides By Address, By City and State, and Cities by ZIP routes. By Address uses a required street address, city, and state, with optional company, apartment or suite, urbanization code, and ZIP fields. The city/state route can return the ZIP list for that city and state. USPS says its result does not confirm a person or company.
| Street address | Required for an address-based delivery check. |
|---|---|
| City and state | Required with the address route. |
| Apt/Suite/Other | Optional when part of the delivery address. |
| ZIP Code | Optional input for the address route, or the starting point for Cities by ZIP. |
Enter the address as a delivery question, then use the result as one part of a records search. It does not prove township jurisdiction, parcel ownership, or who receives mail there.
Keep the returned city spelling and ZIP together with the date checked. An old directory, deed, or family document may carry a different place label, especially where an address sits close to a neighboring postal area. The county’s parcel community field and legal description can test the local-government geography without assuming that USPS wording and township jurisdiction are the same thing.
Washington Township ZIP Code Examples
The township civic center at 57900 Van Dyke Road uses Washington, Michigan 48094. In contrast, Graubner library and other north/Van Dyke addresses use Washington, Michigan 48095. Macomb County’s farmers-market material gives two more 48095 delivery examples: Raven Oaks Farm on 29 Mile Road and Van’s Valley on Van Dyke. These examples establish local postal use. They do not draw a ZIP boundary or establish a list of every street within either area.
That north-and-south contrast is the key local geography detail. A complete address, rather than a ZIP alone, is the right starting point when a record search needs to be tied to a parcel.
Washington Township ZIP Code Map Neighbors
The Michigan DTMB ZIP map places 48094 and 48095 around Washington and shows Romeo, Ray, and Richmond ZIPs nearby. The map also warns that a ZIP boundary is not an official postal boundary and does not coincide with a Census ZIP Code Tabulation Area. Use it as a regional orientation tool, then rely on USPS for delivery and the Macomb parcel system for a local government geography question.
Nearby 48065, 48096, and 48062 are therefore useful warning labels. They show why a search result that says Romeo, Ray, or Richmond should not automatically be assigned to Washington Township without checking the parcel community field and legal description.
Washington Township ZIP Code Boundaries
Washington Township is a charter township, not an incorporated Washington city. A Washington postal city on an address is compatible with the township, but it is not municipal proof. Compare the ZIP result with the Macomb Parcel Explorer’s community, E911 address, Tax ID, and legal description. For recorded land questions, the legal description remains more stable than a postal string.
- ZIP Code
- A postal routing code for delivery geography.
- ZIP+4
- An added delivery segment that refines a ZIP Code for a more specific destination.
- Carrier route
- A mail-delivery sequence, not a municipal or parcel boundary.
- Postal city
- The city name USPS uses for delivery, which may differ from local government jurisdiction.
Note: The reviewed sources did not locate a Washington Township ZIP realignment, renumbering, or annexation record with a reliable date.
Washington Township ZIP Code Directory Searches
Once USPS verifies an address, switch from postal geography to the right local record key. BSA Online accepts address, name, and parcel-number searches, but the static official material did not expose a ZIP field. The Macomb Parcel Explorer uses E911 address autocomplete and a Community filter, not a documented ZIP-wide search. Its guide says to omit road suffixes such as RD, DR, AVE, BLVD, and CT for better address matching.
- Check the full delivery address with USPS.
- Search that address in the Macomb Parcel Explorer and confirm the Community result.
- Record the Tax ID and legal description if the question concerns the parcel.
- Use the BSA property page or deed index for their limited record questions.
For an address-by-address parcel process after a ZIP narrows the area, use the Washington Township streets directory. The ZIP code directory does not supply an address-wide household list.
The Parcel Explorer’s E911 search accepts a full or partial address, and its Community and Property Name controls can narrow a result. BSA’s publicly documented choices are address, name, parcel number, sale date, sale price, property class, and several property characteristics. The official static material did not establish a ZIP field for either tool. Do not represent a normal address match as proof that either system can run a complete ZIP-wide query.
Washington Township ZIP Code Election Limits
Michigan Voter Information Center asks for a ZIP as part of a known individual’s lookup. That ZIP is an identity input, not a public ZIP-wide voter export. Precincts, polling locations, and election administration are also separate from postal delivery areas. For an election record request, use the county election office’s documented request route and ask for an existing record rather than a new ZIP-based people list.
Macomb County’s elections page identifies local election information and clerk links.
Election administration can help locate the proper custodian, while postal geography remains a separate question.
Michigan’s election transparency guidance explains that voter-list requests follow their own process rather than ordinary FOIA workflow.
The state guidance reinforces the distinction between a known-voter check, an authorized request, and a ZIP code.
Washington Township ZIP Code Data Limits
A ZIP Code is useful for delivery verification, but it is a weak key for personal-record research. USPS does not confirm a person or company from its result. The assessor and GIS systems are parcel tools, and the voter tool is an individual-status tool. A name, parcel, court case, vital event, or recorded instrument has its own custodian and access rules. Combining those narrow results does not make a public ZIP directory of people.
Michigan public-record access is record by record. The Michigan Freedom of Information Act can reach an existing nonexempt record that is described with reasonable detail, but it does not require a public office to create a new compilation for a postal area. The custodian may separate exempt information, protect a confidential address, or direct a request to a different office. An address protected through Michigan’s Address Confidentiality Program is not a gap to fill by comparing other systems.
Use ZIP information for its intended purpose: confirm a delivery location, narrow an address search, and distinguish adjacent postal labels. Stop when the next step would infer a person, a private contact point, or an address the source does not publish.
Washington Township ZIP Code Continuity
Macomb materials refer to Van Dyke, Romeo Plank, and mile roads including 26, 27, 28, 29, 30, and 32 Mile. A historical search may encounter an older rural route, road naming variation, or parcel split. The research did not locate an official Washington Township street-renumbering or street-renaming history with dates. Use plat maps, adjacent parcels, legal descriptions, and period newspapers to bridge a mismatch instead of guessing from a current ZIP.
For a record trail, the stable sequence is delivery address to E911 location to Tax ID and legal description. The Washington Township ZIP code directory is the first delivery check, not the final geographic answer.
