Cottage Lake ZIP Coverage
Three codes require different levels of confidence. The strongest parcel evidence links 98072 to the Cottage Lake voting district. USPS documented the creation of 98077 from former 98072 deliveries. King County maps 98052 in the region, but no official source found in the research proves that it crosses the Cottage Lake census boundary. A careful ZIP code directory preserves that gap.
| ZIP | Area evidence | Postal office or city | Directory note |
|---|---|---|---|
| 98072 | District report for a Cottage Lake voting-district parcel | Woodinville postal label | Verified for part of the community |
| 98077 | Created from 98072 deliveries in 2003 | Woodinville Main Office | Search both codes across the change |
| 98052 | Official regional ZIP polygon | Regional preferred-city field | Exact CDP overlap remains unresolved |
These are search keys, not resident rolls. Confirm the address through USPS, then select its parcel in county tools. A Woodinville postal city does not prove Woodinville city jurisdiction.
Cottage Lake's 2003 ZIP Split
The USPS Postal Bulletin says 98077 began July 1, 2003. It moved 6,526 deliveries from 98072 and named Woodinville as the postal city. The same household could therefore appear under two codes without moving.
Search pre-split deeds, ads, business filings, and address books under 98072. Search later sources under 98077 too. A code change is a date clue, not proof of relocation.
Date clue. A 98072 address before July 2003 and 98077 afterward may identify the same Cottage Lake parcel.
Search Cottage Lake Residents by ZIP
The USPS ZIP Code Lookup offers By Address, By City and State, and Cities by ZIP. Its first mode accepts a street with a city and state or a street with a known code. Save the standardized result before opening county records.
- Enter the complete street and unit in USPS By Address.
- Search that address in the King County Parcel Viewer.
- Select the parcel and save its PIN, ZIP, and jurisdiction report.
- Compare its shape with the official ZIP polygon layer.
- Search old sources under the current and historically supported codes.
Once the area narrows to a road, use the Cottage Lake street directory for the address and parcel chain. ZIP is the broad filter; the parcel number makes the match precise.
Cottage Lake Postal Search Fields
USPS standardizes delivery, while county tools connect an address to land. The Property and Permit Guide also accepts street address plus ZIP for unincorporated property work.
| Official tool | Fields | Supported result |
|---|---|---|
| USPS By Address | Street plus city/state or ZIP | Delivery format and assigned code |
| USPS By City and State | City and state | Codes tied to a postal city |
| USPS Cities by ZIP | ZIP | Recognized city labels |
| County permit guide | Street address plus ZIP, or PIN | County property and permit route |
| County ZIP GIS | ZIP, county, preferred city, type, geometry | Mapped polygon context |
Record the check date. Live forms and mapped edges can change, and the required markers were not documented for every interface.
Cottage Lake ZIP Polygons
The King County ZIP GIS layer contains 273 polygons across six counties. Fields include ZIP number, county, preferred city, type, object ID, and geometry. Its history records edits in 2022 and 2023 around 98072, 98077, and 98052.
The official layer screen below shows the map source without exposing resident data.

Cottage Lake ZIP Boundary Limits
Cottage Lake is a Census Designated Place, not a city. A code serves mail, while a CDP serves census geography. Neither determines which agency regulates a parcel. One county report can separately show county jurisdiction, Cottage Lake voting district, Northshore schools, Woodinville Fire and Rescue, watershed, and Woodinville postal city.
Do not use a ZIP code directory as proof of residence, ownership, voting status, school attendance, or incorporation. Select the parcel and read its jurisdiction first.
- ZIP code
- A five-digit USPS delivery area, not a city border.
- ZIP+4
- Four added digits that refine a delivery segment.
- PO-box ZIP
- A code type assigned to post-office boxes.
- Unique ZIP
- A code assigned to one large recipient.
- Carrier route
- A group or sequence of stops served by a carrier.
Cottage Lake ZIP Voter Context
King County My Voter Information is not a ZIP-wide name list. It requires any three of first name, last name, date of birth, and house number. Results can show status, districts, ballot details, voting place, and tracking. A parcel district report confirms geography, not a person's registration.
Statewide extracts have separate approval and use limits under RCW 29A.08.710, .720, and .740. Retain only lawful public fields and date every check.
Historic Cottage Lake ZIP Clues
Older households may appear under Woodinville, Bothell, Redmond, a rural route, an old road, or no modern code. Search the surname with each supported place form. Preserve what the source prints.
For early work, legal descriptions, school districts, township and range, parcel history, and Squak Slough or Sammamish River variants can succeed where a modern ZIP search fails. A mismatch calls for a date comparison, not rejection.
Resolve a Cottage Lake ZIP
Keep each answer with its source. USPS answers mail format. County GIS shows polygons. Parcel Viewer and district reports show parcel context. Census geography answers CDP placement.
For 98052, state only what is known: the code appears in the regional layer, but its exact Cottage Lake intersection was not verified. Check a real address in USPS and parcel GIS.
A researched parcel report showed King County jurisdiction, Cottage Lake voting district, ZIP 98072, Council District 3, congressional district 8, legislative district 45, Northshore School District 417, and Woodinville Fire and Rescue. Save those as separate fields. One address can sit within many systems.
The Census profile defines Cottage Lake as a CDP with 22.74 square miles and 22,857 residents in 2020. Those numbers describe statistical scope, not any one postal area. Do not split them among ZIPs without an official cross-tabulation.
When a historic hit lacks a street match, try the printed postal city, rural route, legal description, school district, watershed, and dated newspaper terms. Require a second source to tie the name to the land. A ZIP can focus the work, but it cannot prove identity.
A mapped edge deserves a second look. Inspect nearby polygons and record the base-map date. County edits may reflect postal or emergency-service updates, while a scanned directory stays fixed to its publication year. Keep both facts. An old source is not wrong just because today's delivery code differs.
Save the standardized address, PIN, preferred city, ZIP type, polygon date, and source link. If a result changes, this log shows which layer moved and which record stayed fixed. It also keeps postal evidence separate from county jurisdiction and Census geography.
For an unresolved match, ask only the next answerable question. USPS can settle the mail form. A district report can settle current jurisdiction. A dated deed can preserve the return address then in use. A directory can show how a household was listed that year. Together, those sources explain change without forcing one boundary system to answer for all the others.
Note: Save the ZIP result, PIN, layer date, and jurisdiction together so later changes can be checked.
