Farmington ZIP Coverage by Postal Place
Farmington’s ZIP code directory needs four verified local signals, not a single town-wide polygon. Ordinary Farmington addresses commonly use 06032. Unionville uses 06085 even though Unionville is a village and postal identity inside the town. UConn Health uses 06030 for its medical and academic campus. 06034 appears in a Farmington Historical Society mailing context and should be treated as a mailing or institutional possibility until USPS confirms a complete address.
| ZIP Code | Area or Postal Signal | Post Office Label | Boundary Note |
|---|---|---|---|
| 06032 | Ordinary Farmington street and town addresses | Farmington | Verify each delivery address with USPS |
| 06085 | Unionville village and many Unionville addresses | Unionville | Postal label remains within Farmington; edges can cross town lines |
| 06030 | UConn Health campus | Farmington | Institution-specific ZIP, not an ordinary residential area |
| 06034 | Historical Society mailing context and possible PO-box or business line | Farmington | Do not map it as a street-delivery polygon |
Adjacent ZIPs may serve edge addresses, but the research did not produce a complete USPS export. The practical rule is simple: keep the full address, city, state, and returned ZIP together. A ZIP code directory can describe verified postal signals, not promise every delivery boundary.
Farmington and Unionville ZIP Context
Unionville is a historic village and postal place within Farmington. The Unionville Museum’s history says the post office adopted the Unionville name in 1834. That label can appear in a mailing line even when the legal town, parcel, deed, and assessor record say Farmington. A ZIP code directory should preserve both the postal string and the municipal identity.
Old directories, newspapers, and maps may use Farmington, Unionville, or a broader Hartford-area label for the same place. When an address seems to change, compare the parcel ID, MBL, legal description, nearby owners, and map rather than relying on a city name.
Farmington UConn Health ZIP 06030
06030 is the UConn Health campus ZIP used by official UConn Health pages. It is a distinctive institutional signal inside Farmington, not a normal neighborhood polygon. A record returned with Farmington, CT 06030 may describe a campus office, department, or institutional mail line. Verify the physical street address before connecting the result to a person or parcel.
The distinction matters for professional, business, and license searches. A campus address can explain a Farmington connection while the person’s residence is elsewhere. Keep the organization and the individual as separate record subjects.
Farmington 06034 ZIP Mail Context
06034 appears in a Farmington Historical Society mailing context and in postal material describing preferred-city and ZIP changes. The research did not verify it as a broad street-delivery area. Treat 06034 as a possible mailing, PO-box, or institutional line until USPS returns the ZIP for a complete address.
A mailing ZIP can identify where a letter goes without identifying a parcel, household, or current resident. It is still useful when paired with an official organization page, a business filing, or a town address, but it should not be used to draw a town-wide boundary.
Verify a Farmington ZIP With USPS
The USPS address lookup is the practical authority for one delivery address. Enter the complete street address, city, and state. Save the returned ZIP and preferred city exactly. USPS explains that a preferred city name and ZIP area can differ from a municipal boundary, which is why a town name alone is not enough.
Use the USPS result before joining a parcel, tax, voter, business, or library record. The five-digit ZIP identifies a delivery area. ZIP+4 refines the route. Neither one converts a postal area into a legal neighborhood.
The USPS ZIP Code basics source provides the postal context shown below.
The USPS image reinforces the address-first rule: confirm delivery with the postal custodian before interpreting the ZIP.
Farmington Portals and ZIP Filters
The inspected Farmington Assessor interface does not expose a ZIP field. It searches by property use, owner, house number, street, unit, MBL, unique identifier, and condominium complex. GIS accepts name, house, street, and unique parcel ID. The public voter lookup is dynamic, and a full voter-file request is controlled by SOTS law. Business and eLicense searches can accept city and ZIP, but they return registered entities or credentials.
| USPS | Complete street address, city, and state return the practical delivery ZIP. |
|---|---|
| Assessor | Owner, house, street, unit, MBL, unique ID, and use fields; no inspected ZIP filter. |
| GIS | Name, house, street, or parcel ID; map context rather than a ZIP roster. |
| Business and eLicense | City and ZIP filters for entities or credentials, not all residents. |
A ZIP-first search therefore has two stages. First confirm the postal result for the complete address. Then move to the record system that answers the actual question: parcel and deed for land, voter rules for registration, business search for an entity, or the Farmington Room for an older household. A portal that accepts ZIP is not automatically a people directory.
Farmington Situs and ZIP Addresses
The situs is the physical parcel used by the Assessor, GIS, and many permits. The mailing line is used for tax correspondence or organizational mail. USPS assigns a delivery ZIP to the full address. A UConn campus line, Unionville postal label, PO box, or business address can fit Farmington’s postal landscape without describing a residential parcel.
For a reliable resident lookup, write the three fields side by side. If the name appears only on a mailing line, say so. If the parcel card and USPS result disagree, check the address with GIS, the Town Clerk, or the responsible office before searching by name.
Farmington Address History Across ZIP Labels
Older Farmington address research can move through Farmington and Unionville labels, house-number changes, subdivisions, and parcel splits. The Farmington Room’s directory run covers 1907-2006, the Farmington Valley Herald is digitized from 1894-1975, and the GIS includes a 1934 aerial alongside later layers. These time slices can show an older road, farm, mill corridor, or village phrase that explains a modern postal mismatch.
Match a historical address with a deed legal description, MBL, unique ID, map, or adjoining owner. A similar street name is not enough. The older directory and current ZIP can describe the same place in different systems.
Farmington Population and ZIP Context
Census QuickFacts estimates Farmington’s July 1, 2025 population at 28,632, with a 2020 estimate base of 26,708. Its profile also reports age, birthplace, race, poverty, and owner-occupied-unit measures. These numbers provide civic context, not a list of residents by ZIP and not proof that a person lives at an address.
The Census QuickFacts source supplies the aggregate context shown in the first image.
The QuickFacts image belongs in the context layer, where aggregate numbers are kept separate from an address-level ZIP search.

Find Farmington Residents by ZIP Code
A ZIP code directory is a narrowing tool, not a resident download. Farmington’s Assessor search uses owner, street, house, MBL, unique ID, and condominium fields, but the inspected interface does not expose a ZIP filter. GIS uses name, house, street, and unique parcel ID. The business and eLicense portals accept city and ZIP filters for entities or credentials, not every resident. USPS is the authority for the delivery ZIP on one complete address.
- Write the complete Farmington or Unionville address, including the postal city, state, unit, and ZIP already in hand.
- Check that address through the USPS ZIP Code Lookup, then save the returned postal result.
- Use the Assessor or GIS search to move from the confirmed address to a parcel, owner field, MBL, or unique ID.
- Use voter information only through an official, permitted route. A ZIP-wide file request requires a lawful statutory purpose and costs $300 through SOTS.
- Once the ZIP narrows the location, move to the street-by-street work on the Farmington street directory page.
Do not treat a business, credential, institution, or PO box hit as a household result. Preserve the record type so a postal clue does not become an unsupported resident claim.
Farmington ZIP Code Directory Versus Town Lines
USPS assigns delivery routes, not municipal borders. Unionville’s postal name was adopted in 1834, but Unionville is not a separate municipality. A Farmington legal address can use a Unionville mailing line, and a campus or organization can use a special ZIP that says little about a residential parcel. Census ZCTAs are statistical approximations and do not replace the address result from USPS.
That mismatch matters when a name search crosses systems. The assessor and GIS key on physical situs and parcel. Tax or voter records may use residence or mailing fields. USPS keys on a complete delivery address. Keep all three labels in a note and do not join records just because the city name or ZIP looks familiar.
- ZIP versus ZIP+4
- A five-digit ZIP identifies a delivery area; the four extra digits refine a specific route or segment.
- PO-box ZIP
- A ZIP used for post-office boxes or a mailing line, not necessarily for street delivery.
- Unique ZIP
- A ZIP assigned to a major institution or special organization rather than a broad residential area.
- Carrier route
- A postal delivery path inside a ZIP, not a legal neighborhood or parcel boundary.
