Martha Lake ZIP Coverage
No official source reviewed publishes a parcel-by-parcel table of every ZIP inside the Martha Lake Census-Designated Place. County survey responses document several local postal labels, while park and service pages add nearby examples. The entries below therefore distinguish strong local evidence from survey or service-area clues. Use the USPS ZIP Lookup for the final answer on one address.
| ZIP | Local evidence | Verification route | Boundary note |
|---|---|---|---|
| 98087 | Common Martha Lake and Lynnwood label; county park addresses use it | USPS address mode | Strongest observed local ZIP, but not identical to the CDP |
| 98012 | Martha Lake survey responses and nearby county service geography | USPS address mode | Mill Creek or Bothell labels may occur near the edge |
| 98037 | County survey responses and service-map coverage | USPS address mode | Local use does not place every address inside Martha Lake |
| 98208 | Martha Lake survey responses | USPS address mode | Survey evidence only; verify the individual address |
| 98036 | Lynnwood-area curbside service material | USPS address mode | Nearby service geography, not confirmed CDP-wide coverage |
| 98046 | Lynnwood-area curbside service material | USPS address mode | Special or alternate local label; verify each address |
98087 has the clearest Martha Lake connection in official local material. Martha Lake Park uses a Lynnwood 98087 mailing address even though Martha Lake is not part of an incorporated Martha Lake city. The other codes are useful leads, not boundary verdicts. No official Martha Lake-specific ZIP split or realignment ledger was found, so historical claims need address-level USPS data, deeds, plats, and dated directories.
Martha Lake Is Not a ZIP
Martha Lake is a Census-Designated Place in unincorporated Snohomish County. A CDP is a Census geography used for statistics. It is not a city government, post office, or ZIP boundary. A mailing label may say Lynnwood even when Snohomish County handles property, recording, permit, and court records for the parcel.
This distinction prevents a common routing mistake. First identify the parcel in the SCOPI Interactive Map. If it falls in unincorporated county territory, county PDS is the likely permit custodian. A parcel within Lynnwood or Mill Creek city limits may instead route to that city's office, regardless of the familiar Martha Lake place name.
Boundary rule. A ZIP delivers mail. SCOPI and the parcel record identify jurisdiction for a Martha Lake records request.
Check Martha Lake Postal Labels
USPS offers three lookup modes: ZIP by address, ZIPs by city and state, and cities by ZIP. Address mode is the best choice when several local labels are possible. It requires a street address, city, and state; apartment or suite, company, and ZIP fields are optional. A recommended city name may differ from the community name a resident uses.
- Enter the full street address in USPS address mode and save the recommended city and ZIP.
- Run cities-by-ZIP to see whether USPS recognizes more than one city label for that code.
- Compare the result with the parcel's situs address and SCOPI jurisdiction.
- Carry the verified parcel or address into PDS, Treasurer, or recording searches.
USPS expressly warns that a ZIP result does not confirm that a person or company is at the address. That insider detail matters for a resident search. Postal validation proves a delivery format, not occupancy, ownership, or identity.
Note: The required USPS screenshot failed with HTTP 403, so no image is presented as proof of the live form's current appearance.
Search Martha Lake by ZIP
Few official local portals provide an unrestricted ZIP-wide resident browse. PDS Online Records includes ZIP among its result metadata and filters, which can narrow permit and land-use documents. That filter searches the digitized PDS collection, not every parcel or person. The Assessor and Treasurer tools are address, parcel, owner, taxpayer, or mailing-address searches rather than documented ZIP-wide lists.
- Validate the postal city and ZIP through USPS before using a county system.
- Search PDS Online Records by address or parcel, then use ZIP and city metadata to narrow the returned documents.
- Use SCOPI to inspect the parcel and nearby county geography rather than treating a ZIP as a boundary layer.
- For lawful voter-data research, follow the Secretary of State request process and its statutory use limits.
Once a ZIP narrows the area, switch to the Martha Lake street directory for the address-by-address workflow. Street numbers and parcel IDs are more precise than a postal zone, especially where one ZIP reaches adjacent communities.
Martha Lake ZIP Permit Filters
The PDS Online Records portal searches unincorporated county permit and land-use files. It accepts Tax Parcel, Permit, or Address as the main search type. Results may include parcel, related parcel, city, ZIP, property address, related address, permit number, folder, description, and type. Wildcards and result filters can broaden or narrow the set.
| Portal field | How it helps | What it does not prove |
|---|---|---|
| ZIP and city | Narrows digitized permit results by postal metadata | CDP or city-limit membership |
| Property address | Connects a file to its site | Current household |
| Tax parcel | Keeps the site stable across label changes | That every old file is online |
| Related address or parcel | Flags linked projects and parcel changes | That all related land lies in one ZIP |
Not every PDS record is online. When no digital result appears, use the PDS Information Request Form with the site address, parcel, and permit or project number. The form is also the documented route for staff help and copies.
Three Martha Lake Address Fields
A reliable ZIP code directory keeps three county address fields separate, then records the postal city and ZIP as delivery data. The situs address names the physical parcel. The mailing address is where the taxpayer receives notices and may be somewhere else. The legal description identifies the land by lot, tract, plat, or survey even if a street number changes.
- Situs address
- The county's address for the physical property shown in parcel and permit systems.
- Mailing address
- The destination used for tax or owner mail, which does not establish residence.
- Legal description
- The deed and plat language that follows the land across postal or street changes.
- ZIP+4
- A ZIP plus four digits that narrows mail delivery below the five-digit area.
Copy these fields exactly before searching recorded documents. A legal description can bridge an old deed to a modern parcel when the postal city or road number changed. A mailing address, by contrast, may identify only the destination for a bill.
ZIP Codes Cross Martha Lake
Martha Lake South is east of I-5 between Lynnwood and Mill Creek. County material describes a 61.6-acre lake within a 437.7-acre watershed. Water, drainage, road, park, and mail boundaries answer different questions, so none should substitute for the parcel map.
The county stormwater project at Meadow Road and 156th Place NE describes runoff entering Martha Lake. That project illustrates why a civic record may use a lake or watershed label while its street address carries another postal city. Martha Lake Park at 16300 East Shore Drive and Martha Lake Airport Park at 200 146th Street SW are useful public anchors, but their addresses do not define the entire CDP.
The county curbside service page similarly groups ZIPs by operating area. Use that map to check service coverage, not to infer who lives in a home or which government owns every record.
Trace Martha Lake Before ZIPs
Historical resident work should not force a current ZIP onto a record created before that delivery label existed. Older directories may organize entries by town, street, telephone exchange, or surname. A deed may rely on a plat and legal description with no modern street number. Rural Martha Lake coverage can also be absent from directories built around larger nearby cities.
Start with the present parcel and legal description. Then compare old deeds, plats, directory street sections, census schedules, and historic maps for the same land. The Martha Lake city directory collections route explains the regional Snohomish and Everett volumes, while the past residents workflow follows one address backward. The Library of Congress has 1897 and 1905 Snohomish Sanborn material, but a map is useful only if the road or nearby settlement is actually drawn.
No complete official reverse-directory run for Martha Lake was located online. Sno-Isle Libraries, the Washington State Library, and the Snohomish Historical Society are the fallback channels for directory, telephone-book, newspaper, and local map questions. Record the year and geographic scope of each source, including a clear gap when the area is missing.
Note: A missing directory year or unmapped road is a coverage gap, not evidence that an address or resident did not exist.
Martha Lake ZIP Boundary Limits
A five-digit ZIP is an efficient sorting area, not a legal city boundary. One code can serve a city, an unincorporated pocket, and addresses using more than one accepted community label. Martha Lake's CDP boundary comes from the Census, jurisdiction comes from county and city maps, and the delivery label comes from USPS.
- ZIP code
- A five-digit USPS mail-sorting area that can cross local government lines.
- PO-box ZIP
- A code used mainly or only for post-office boxes rather than ordinary street delivery.
- Unique ZIP
- A code assigned to one organization receiving a very large volume of mail.
- Carrier route
- A smaller delivery path within a ZIP used by a mail carrier.
For older addresses, modern ZIP searches are even less reliable. Pair plats, deeds, old directories, telephone exchange names, and Sanborn maps where the road is actually covered. No official web-published Martha Lake address-renumbering history was located. Preserve uncertainty instead of assigning a modern ZIP to an old address without evidence.
