Fairmont ZIP Coverage at a Glance
The postal core is 26554, while 26555 appears as a Fairmont PO Box or mailing variant. Nearby offices in Barrackville, Rivesville, and Kingmont matter when an edge address or familiar place name produces an unexpected result. This Fairmont ZIP code directory separates primary city postal use from nearby service points. It does not claim that every address tied to a postal name lies within city limits.
| ZIP Code | Areas Covered | Post Office | Notes |
|---|---|---|---|
| 26554 | Standard Fairmont delivery area; associated postal names may extend beyond the city | Fairmont Post Office and East Side station | Verify each full address with USPS |
| 26555 | Fairmont PO Box and mailing contexts | Confirm the box-service counter with USPS | Does not locate a building or household |
| 26559 | Nearby Barrackville delivery area | Barrackville office | Not a Fairmont city ZIP |
| 26588 | Nearby Rivesville delivery area | Rivesville office | Useful for edge-area checks |
| 26578 | Nearby Kingmont delivery area | Kingmont office | Not proof of a Fairmont city address |
Established postal datasets associate 26554 with names such as Bellview, Jordan, Monongah, Pleasant Valley or Pleasant Vly, and White Hall. Those can be postal aliases or carrier-area clues, not a definitive official list. No static USPS table of every Fairmont alias was found. Use the live USPS ZIP Lookup for the address at issue.
Search a Fairmont ZIP with USPS
USPS offers three different searches, and each answers a different postal question. The address tab is best when the street is known. City and State returns ZIP information for a locality. Cities by ZIP reverses the check and reports the place names tied to one code. The tool is free, and no login was observed during research.
| USPS field or mode | Entry type | Use in a Fairmont search |
|---|---|---|
| Company | Optional text | Add only when checking business mail |
| Street Address | Required on address tab | Enter the delivery line; add Apt/Suite/Other when needed |
| City, State, ZIP | Fields vary by tab | Use Fairmont and West Virginia, or reverse-search one ZIP |
| Find | Search control | Review the standardized postal response |
The postal result formats mail. USPS expressly warns that a returned result does not confirm that a person or company is at an address. In other words, the strongest postal match is still not an occupancy record.
Fairmont ZIP Code Service Counters
The Fairmont Post Office is at 331 Madison Street, Fairmont WV 26554-9998, and its listed phone is 304-366-1610. Captured hours showed Tuesday through Friday from 8 a.m. to 5 p.m., Saturday from 9 a.m. to noon, and Sunday closed. Monday hours should be checked on the live location page before a visit.
The East Side Post Office is at 215 Merchant Street, Fairmont WV 26554-9995, phone 304-366-2636. Its captured schedule showed Monday through Friday from 9 a.m. to 4 p.m. and Saturday from 10 a.m. to noon. These counters share the main postal area but are distinct facilities. A station suffix such as 9995 or 9998 is not the same thing as a household ZIP+4.
USPS nearby-office links also point to Barrackville, Rivesville, and Kingmont. Check the live location record for hours and services, since schedules can change. Note: a nearby post office can serve a useful mailing role without making its ZIP part of incorporated Fairmont.
If online results fail, take the full address to the postal counter or call the listed station. Ask whether the issue is an invalid delivery line, a missing unit, a changed preferred city name, or box service. Keep the response with the date and station name. Postal staff can clarify mail format, while questions about city limits or parcel ownership still belong with the map or county record keeper.
Narrow Fairmont Records by ZIP
A ZIP can reduce a broad search, but Fairmont's official systems do not publish one ZIP-wide roster of residents. Start with postal validation. Then use parcel or civic geography only for the purpose that created that record. The Marion County Assessor connects owner, parcel, and mailing details, while statewide assessment results add district, map, parcel, land-use, acreage, and a GIS link. Those are property facts, not a statement of who sleeps at an address.
- Run the full address through USPS and save the standardized city, state, and ZIP response.
- Check the Marion County Assessor by parcel address, owner, account, district, or map and parcel.
- Compare the parcel with the West Virginia Parcel Viewer and note city limits or district boundaries separately.
- If an authorized voter-data task requires a geographic list, follow the state request form and its signed noncommercial-use certification.
- Once the search reaches a named road, use the Fairmont street directory for the address-level record chain.
The assessor portal does not provide a documented ZIP field in the captured form. Its tested fields include owner name, parcel address, account number, district, map and parcel, property type, legal description, and deed book and page. Do not claim that it can return every parcel in one ZIP unless the live system actually offers that control.
Fairmont Has Two Address Geographies
Every useful worksheet should carry two sets of labels. Postal geography comes from USPS: street, city name, state, ZIP, and, when given, ZIP+4. Government geography comes from official maps and rolls: incorporated city line, county, tax district, precinct, parcel, and map references. One address can have a Fairmont postal label while sitting outside the corporation boundary.
The Fairmont ArcGIS city-limits item includes layers for city limits, neighborhoods, municipal services, transport, recreation, and nearby cities. The city Planning Department confirms that it manages municipal GIS and maps. Exact public attribute-search controls were not stable in the captured text, so use the map for visual context and confirm legal questions with the relevant custodian.
| Postal label | USPS city, state, ZIP, and delivery formatting |
|---|---|
| Municipal label | Whether the point lies within Fairmont's incorporated boundary |
| County parcel label | District, map, parcel, legal description, and assessment fields |
| Election label | Precinct and districts maintained for voter administration |
Fairmont ZIP Aliases Need Proof
Bellview, Jordan, Monongah, Pleasant Valley, Pleasant Vly, and White Hall appear as Fairmont-area associations in established postal datasets. That list is useful for diagnosing a failed search. It is not a stable official roster of aliases, neighborhoods, or city territory. Repeat an address search with the live USPS tool before changing the locality on a form.
This is a common myth in ZIP research: a recognized postal city does not establish that a person resides within that municipality. Postal systems route mail. City governments define corporate limits. County offices maintain parcels and districts. Each boundary was made for its own task, so each result should keep its source label.
When an old letter, directory, or family file uses one of these place names, preserve the wording as written. Add a second field for the modern USPS response and a third for the mapped government boundary. This small habit prevents an alias from silently becoming a claim about city residence. It also makes later corrections easy when USPS updates a preferred city name or a local boundary changes.
Fairmont Street Changes Leave Filings
West Virginia law creates a strong trail when local geography changes. Under W.Va. Code §3-2-19, a municipality files a certified boundary map and street-range list with the county clerk within 30 days after annexation, a street-name or number change, or a related boundary change. That filing can explain why an old address fails in a modern ZIP code directory.
Ask the Marion County Clerk or the City of Fairmont for the specific map and street list. Keep the filing date, old and new street range, and affected precinct with the research notes. The statute points to a record, but it does not prove that every historical filing is online.
Compare Fairmont ZIP and City Limits
The final check is a comparison, not a single search. Confirm the postal answer through USPS. Plot or inspect the parcel through county or state GIS. Then compare it with Fairmont's city-limit layer and the relevant tax or election district. If the sources disagree, report both labels and their dates instead of forcing one boundary to answer a question it was not designed to settle.
- ZIP and ZIP+4
- A five-digit postal zone and a more precise four-digit delivery segment added to it.
- PO-box ZIP
- A code or mailing variant used for post office boxes, which does not locate a building.
- Unique ZIP
- A code assigned to one high-volume organization. No definitive Fairmont unique assignment was established.
- Carrier route
- A mail-delivery path within a ZIP. It is not the same as a neighborhood or city boundary.
Fairmont covers 8.60 square miles, while Census QuickFacts reports a 2020 population of 18,416 and a 2025 estimate of 18,035. Those figures describe the city as Census defines it, not the whole 26554 delivery area. The difference shows why per-ZIP population claims need a source built specifically for ZIP geography. No official Fairmont ZIP-wide population or voter table was located.
A careful Fairmont ZIP code directory result therefore reads in layers: USPS formatting first, municipal boundary second, and parcel or precinct context third. That method is slower than treating a ZIP as a city line, but it leaves a clear source trail and avoids turning a mailing label into a claim about any person.
