Lyon Township ZIP Coverage
The official township map labels six postal areas: 48165, 48167, 48178, 48380, 48381, and 48393. Its companion township page says five post offices serve Lyon Township. Both statements are true because Milford appears on the map with two postal labels. The map provides a starting geography, not parcel-by-parcel boundaries. Check a complete address with USPS before using any label on mail or assuming an address belongs to a township.
| ZIP Code | Areas Covered | Post Office | Notes |
|---|---|---|---|
| 48165 | New Hudson-labeled area on the township map | New Hudson | The Lyon Township municipal center uses this mailing label. |
| 48167 | Northville-labeled area on the township map | Northville | Verify the individual address with USPS. |
| 48178 | South Lyon-labeled area on the township map | South Lyon | The township library uses a South Lyon mailing address. |
| 48380 | Milford-labeled area on the township map | Milford postal service | The published map text does not define a parcel-level split. |
| 48381 | Milford-labeled area on the township map | Milford | Second Milford label, distinct from 48380. |
| 48393 | Wixom-labeled area on the township map | Wixom | Verify the individual parcel and mailing label. |
No official township source located a precise neighborhood list, a ZIP+4 boundary file, a population count by ZIP, or a PO-box-only designation for these labels. It is better to preserve that uncertainty than turn a map label into an invented range.
Lyon Township's Five Postal Offices
Lyon Township's ZIP information names New Hudson, South Lyon, Northville, Wixom, and Milford as the five post offices serving the township. USPS organizes these routes for mail delivery, not municipal government. A South Lyon, New Hudson, Northville, Milford, or Wixom mailing city can therefore appear on a Lyon Township address. The reverse can happen as well, which is why the postal city should remain a mailing fact rather than a boundary conclusion.
The two Milford labels are the local quirk. They explain why the map has six labels while the township prose has five post offices. There is no published township source that assigns every Lyon parcel to either 48380 or 48381. USPS address verification is the proper final check for a complete mailing label, while the county property map is the check for situs and municipality.
Lyon Township Postal Survey Labels
The 2024 Lyon Township Master Plan recorded ZIP labels from 957 survey responses. This is not a population table and should not be used as one. It does show how postal geography appears in a local survey: 48178 accounted for 516 responses, 48165 for 363, 48167 for 53, 48393 for 9, 48381 for 8, six outside-boundary labels for 6, and 48380 for none. A zero in one survey does not erase a label on the official map.
| 48178 | 516 responses, 53.92% |
|---|---|
| 48165 | 363 responses, 37.93% |
| 48167 | 53 responses, 5.54% |
| 48393 and 48381 | 9 and 8 responses, respectively |
| 48380 | 0 responses in this 957-response survey |
Postal labels can concentrate in a response set without tracking municipal limits, parcel totals, or every resident. The master-plan figures are useful as a warning against treating a ZIP search as a census.
Note: The master-plan ZIP figures describe survey respondents only, not the number of people or parcels in any postal area.
Lyon Township Postal Address Checks
Use USPS ZIP Code Lookup with a complete street address when the immediate question is a mailing label. Then use Oakland County Property Gateway to confirm the physical parcel and its municipality. This order avoids an easy mistake: a correct USPS result does not establish that the parcel lies inside Lyon Township, and a correct municipal result does not decide how USPS formats the mail.
The USPS lookup is the authoritative route for a specific mailing address.
Save the result with the full address used, then check the property portal with that same address or the parcel identifier.
Property Gateway documents address or PIN search, but not a public ZIP-wide filter. Its documented input accepts a partial street address or a PIN of at least five characters. The map can then be clicked to reach a parcel. That is an address-by-address method, not a way to generate a township-wide list for one postal label.
| Property Gateway field | Use | Format or limit |
|---|---|---|
| Street Address or PIN | Find a parcel | At least five characters; partial address or PIN accepted |
| PIN | Cross map, tax, and deed research | Ten digits, often rendered xx-xx-xxx-xxx; dashes optional |
| Municipality | Confirm location | Identified automatically, with no user selection documented |
| Map mode | Inspect the parcel context | Standard, Detailed, or Hybrid |
| ZIP filter | Not documented | Do not treat the portal as a ZIP-wide search |
Finding Lyon Township Residents by ZIP
A ZIP code narrows a postal area, but the official tools reviewed do not offer a documented public resident filter for it. Property Gateway does not document a ZIP filter, the Michigan Voter Information Center is an individual lookup, and the Register of Deeds simple search does not document a ZIP option. A Qualified Voter File request can be specified by jurisdiction, school, or county codes if the Bureau accepts the request, but it should not be described as a ZIP browse or as a roster for every parcel.
- Use USPS to verify the complete mailing address and its current postal label.
- Enter the address or PIN in Property Gateway and confirm that the municipality is Lyon Township.
- Record the situs address, parcel identifier, and legal description for the question being researched.
- Use the appropriate county or township record source for that identified address, not an assumed ZIP-wide list.
- Check the Michigan voter route only for its documented individual or request-based purpose, with redactions respected.
Once an address is confirmed, the Lyon Township street directory follows the address and parcel trail by street rather than treating the postal label as a boundary.
Lyon Township Postal Boundaries
Lyon Township is a charter township in Oakland County, while its mail can carry several neighboring place names. The township explicitly warns that USPS does not organize addresses around municipal boundaries and that mapping applications can disagree. The safest pairing is USPS for the mailing label and Property Gateway for the physical parcel, municipality, map, and PIN. A street name or mailing city by itself is not enough to settle the boundary question.
- ZIP code
- A USPS delivery-routing label used for mail, not a municipal boundary.
- ZIP+4
- An added delivery segment tied to a more specific address or delivery point; no local ZIP+4 boundary file was located.
- PO-box ZIP
- A postal label reserved for post-office boxes; no PO-box-only designation was documented for the six Lyon map labels.
- Unique ZIP
- A label assigned to a single organization or destination; none was documented for Lyon Township.
- Carrier route
- A USPS delivery sequence within an area, which does not establish a township boundary or a household list.
Do not infer a resident's municipality from the postal city. Verify the exact address, then retain both the mailing label and the situs result in the research notes.
Lyon Township Parcels Across ZIP Labels
The 10-digit Oakland PIN is the durable bridge between the property map, tax information, Register of Deeds index, and a subdivision plat. It may also be called a Parcel Number, Parcel ID, or Sidwell. A legal description can survive when a street label or postal city changes. That makes it more dependable for a historical parcel trail than a ZIP alone.
Property Gateway's Detailed mode shows plat-like parcel and PIN labels, while Hybrid adds aerial imagery with PIN information. Click a parcel after searching an address, then retain the situs address, PIN, and legal description. A tax mailing address may point to an owner, agent, trust, or other recipient outside the township. It does not establish every person who lives at the parcel.
Note: A parcel identifier connects land records, while a postal label routes mail, so neither should be substituted for the other.
Lyon Township ZIP Research Limits
The online sources have clear boundaries. The township map does not publish parcel-by-parcel ZIP ranges. Property Gateway has no documented ZIP filter, and its owner-name search was not documented in the public instructions reviewed. Michigan voter records are public subject to statutory redactions, and Address Confidentiality Program applications are withheld. These limits protect against turning a map or a postal label into a claim the record does not support.
The indexed township map file reviewed during research carried a legacy 2011 date, while the live township page still directs readers to its map. No newer revision date or USPS boundary-change record was located in the source set. For an address close to a postal-label change, treat the map as orientation only and repeat the USPS and Property Gateway checks when the result will be relied upon.
A voter-file request has its own boundary. Michigan's public QVF production may include a redacted residential address, mailing address when available, year of birth, registration date, status, voter ID, and requested history. Phone, email, birth month and day, identifying numbers, signatures, and other protected fields are redacted. The Michigan Voter Information Center is aimed at an individual's registration and polling details, not a ZIP-wide browse. A request should be narrowed only through the documented jurisdiction, precinct, school, or county route.
For an uncertain address, keep a short audit trail: USPS result, Property Gateway municipality and PIN, date checked, and the next custodian needed for the question. The township's official ZIP page, the county map, and USPS each have a different role. Using all three produces a more accurate result than relying on one label from a form or map.
