Northville Township ZIP Coverage
Two postal areas are directly evidenced for Northville Township addresses: 48167 and 48168. Each is part of the broader Northville delivery context, not a municipal line. Township Public Safety and DPW use 48167, while Township Hall on Six Mile Road uses 48168. The table also preserves 48170 as an unresolved edge case rather than calling it Township coverage. Its connection in the research is the 35th District Court's Plymouth address, and that court is not located in the Township.
| ZIP | Areas covered | Post office | Notes |
|---|---|---|---|
| 48167 | Northville postal area; Township Public Safety and DPW addresses | Northville delivery area | Part of the former 48167 area split to 48168 in 2005. |
| 48168 | Northville postal area; Township Hall address | Northville delivery area | Created for part of former 48167; it does not match the Township boundary. |
| 48170 | Possible southern or western mailing edge, not confirmed for Township addresses | Plymouth postal area | Verify each address through USPS and parcel jurisdiction before using it. |
No unique single-institution ZIP or PO-box-only Township ZIP was confirmed in the inspected official sources. No official source supplied a complete address-level list for every Township postal assignment.
Northville Township ZIP 48168 Transition
The local postal change has a firm date. USPS established 48168 effective July 1, 2005 for part of former 48167. The contemporary Northville Record account reported that roughly half of 17,400 addresses then using 48167 changed to 48168, generally affecting homes and businesses south of Seven Mile Road. That count belongs to the dated 2005 account, not a current Township total. The same account said mail using the old code would continue to be delivered for one year.
The USPS Postal Bulletin notice is the official source for the July 1 effective date and the fact that part of 48167 was reassigned.
The notice supports a dated postal change, not a conclusion about current Township borders or the person associated with an address.
Postal changes can take time to settle in address systems. USPS says ZIP updates may take 30 to 60 days to propagate, which is one reason to retain the address and source date when comparing an older record.
Northville Township ZIP Lookup Modes
USPS offers three different lookup paths, each with a narrow purpose. By Address standardizes an address and its postal code. By City and State identifies postal information from those place fields. Cities by ZIP works in the other direction. None of these modes verifies a resident, a business connection, or Township jurisdiction. Use the result as an address-standardization step before consulting a parcel, assessment, or other applicable official record.
| By Address | Company is optional; street address and city/state are required; apartment or suite and ZIP are optional. |
|---|---|
| By City and State | Enter city and state to retrieve the postal result for that combination. |
| Cities by ZIP | Enter the ZIP to retrieve associated city information. |
| Result | A standardized address and postal result, not a municipal or identity finding. |
The USPS ZIP Lookup is the official route for those modes, while the USPS explanation of ZIP basics gives the address-standardization context.
Its ZIP basics guidance explains the postal role behind the lookup modes shown here.
USPS guidance is useful for checking delivery information before a jurisdictional search moves to local parcel records.
Finding Residents in a Northville Township ZIP
No official Township people portal was found that returns every record in a postal area. The available local systems use different keys. Northville Township BS&A displays Address, Name, and Parcel Number modes rather than a ZIP field. Wayne GIS is map and parcel based. The Michigan voter-file route can be requested by jurisdiction, precinct, or district scope, but it is not a public ZIP-wide roster. Postal information narrows an address question; it does not create a reliable people search.
- Confirm the full address with the USPS mode that fits the information in hand.
- Use the confirmed address, owner name, or parcel number in Northville Township BS&A; do not expect a ZIP filter there.
- Check the parcel and municipality through Wayne County Maps and Data when the City and Township boundary is relevant.
- For voter records, use the applicable individual lookup or a properly scoped QVF FOIA route, recognizing that the documented choices are jurisdictional rather than postal.
- Keep the search date, postal result, municipality, and source result together before drawing a conclusion.
Once a verified address is known, the Northville Township street directory route is the better place for the address-by-address record chain.
Northville Township Address Search Fields
The field used by a record changes what it can prove. A situs address is the physical parcel location used by assessment, GIS, permits, and some delinquent-tax searching. A mailing address is where a tax notice goes and may be outside the Township. A legal description identifies the recorded land interest and can remain useful when a street address or postal assignment changes. An owner name on an assessment record is an ownership clue, not a statement that the named person lives at the site.
BS&A's inspected landing page lists Address, Name, and Parcel Number as its search entries, with separate service tabs for detailed records, current tax, property sale, building department, and assessing. Its records are reference information, so the Township should confirm an authoritative question. Wayne County's delinquent-tax route likewise uses street number, street name, municipality, or parcel ID rather than a postal field.
Northville Township ZIP Boundaries
Northville Township and the City of Northville are separate governments. Nearby Novi, Salem, and Plymouth-area addresses can also share postal-city labels or related postal context. The Township Hall's 48168 and Public Safety's 48167 provide a visible example within Township operations: different postal codes do not divide local government. Municipality should be verified in BS&A or GIS, while a legal description is the stronger bridge for recorded title.
- ZIP code
- A postal routing code. It helps delivery and address standardization, but it is not a municipal boundary.
- ZIP+4
- An added four-digit postal detail used to refine delivery routing beyond the base ZIP.
- PO-box ZIP
- A postal code used for post-office boxes; no Township-only example was confirmed in the inspected sources.
- Unique ZIP
- A code assigned to a single institution or organization; no Northville Township example was confirmed.
- Carrier route
- A postal delivery grouping. The inspected sources did not identify it as a Township people-record search field.
Note: A postal-city result should never substitute for the municipality field when deciding whether an address belongs to Northville Township.
Northville Township 48170 Edge Case
48170 should be treated as a verification task, not as a settled Township postal area. The research noted a possible southern or western Township mailing pocket, but it did not obtain complete address-level USPS confirmation. The 35th District Court is at a Plymouth 48170 address and serves Northville Township as part of a multi-community district. Court service coverage does not place the court or every 48170 address in the Township.
For a possible 48170 Township address, use USPS to standardize the exact address, then use the municipality and parcel information. Record a negative result when the sources do not confirm the claimed geography. That approach is more reliable than extending a postal assumption from a court location or a nearby street.
Northville Township ZIP Search Limits
The research found no published per-ZIP Township population, voter-registration, or block-level registration statistics. Census geography and election precincts cannot be silently substituted for postal statistics without a direct crosswalk. It also found no official public export that lists every Township address by ZIP and no Township portal that returns every person or property through a postal filter. These absences shape a careful search workflow.
The Township Clerk holds public records for existing documents and coordinates FOIA, but a request is not a way to require creation of a new resident database. A narrow request should identify the existing record category, department, date range, and search terms. Expect exemptions or redactions where the law requires them. Postal research works best as an address-verification step joined to an existing record, not as a broad list-making method.
Northville Township Postal Geography
For a family-history question, a 2005 mailing change can explain why the same house appears under different postal information in adjacent records. For a current address question, it explains why a Northville delivery label does not prove a City or Township location. The useful sequence is simple: preserve the historical address as printed, confirm its postal form for the relevant date when possible, and then check its municipality or legal description with the appropriate local record.
This geographic distinction also protects against false matches. Two addresses can share the same postal city while falling under different governments, and an old postal code can remain visible in a dated publication after later routing changes. The Northville Township ZIP code directory is most useful when it keeps those layers separate rather than treating the postal field as a boundary or a people list.
