Collinsville ZIP Coverage at a Glance
The official postal anchor is 62234. The USPS Collinsville Post Office listing places that code at the Collinsville station on Eastport Plaza Drive. Other codes appear in nearby-office lists and old regional routing material, but that does not make them current Collinsville city ZIPs. The Collinsville ZIP code directory therefore separates the confirmed mailing code from edge labels that need an address-level check.
| ZIP or label | Area treatment | Post office | Directory note |
|---|---|---|---|
| 62234 | Primary Collinsville mailing area | Collinsville | Extends beyond city limits |
| 62232 | Nearby Caseyville or edge label | Caseyville | Verify the exact address |
| 62062 | Nearby Maryville or edge label | Maryville | Verify the exact address |
| 62201, 62208, 62269 | Nearby postal alternatives | National Stock Yards, Fairview Heights, O'Fallon | Not Collinsville city codes |
No static USPS result inspected in the research supplied a complete list of all addresses that may use the Collinsville place name. That gap calls for care. Use 62234 as the confirmed current code, and test every edge address through USPS and the county parcel system before assigning it to Collinsville.
What 62234 Means in Collinsville
A five-digit postal label describes delivery, not municipal rule. City material says 62234 is larger than Collinsville's corporate limits. Thus, a result bearing “Collinsville IL 62234” may sit outside the legal city. This is the key geographic fact behind the Collinsville postal search and the reason a ZIP-only resident list can contain false matches.
Start with the mailing form, then add the county, parcel number, and source date. A parcel number, often shortened to PIN, is the local identifier assigned to a piece of land. Madison and St. Clair Counties use different property and recording systems, so the correct county selects the assessor, recorder, clerk, and court office. A postal city alone cannot make that choice.
Boundary check. Confirm the city and county in an official parcel or GIS source before treating a 62234 address as a Collinsville record.
Collinsville ZIP Records Cross Counties
Collinsville lies in Madison and St. Clair Counties. For a Madison-side address, search Madison County DEVNET. It accepts parcel, owner, site-address, mailing-address, sales, document, tax-year, township, district, class, land-use, and ZIP fields. A St. Clair-side address belongs in the St. Clair parcel inquiry. Neither portal should be treated as citywide by itself.
The St. Clair property screen is one of three images assigned to this Collinsville ZIP code page. View the official St. Clair parcel search before using the form.
The image shows why county selection comes before any parcel claim. It supplies a county-specific search route, not a universal list of Collinsville residents.
Search Collinsville Residents Within a ZIP
A ZIP code directory narrows geography. It does not identify a person on its own. Build a careful result by moving from the postal label to an official record created for a known purpose. Keep the address exactly as each source prints it, since a mailing address and a site address can differ.
- Confirm the city, state, and postal form with the USPS lookup tied to the Collinsville station.
- Determine whether the parcel lies in Madison or St. Clair County.
- Search the matching assessor by site address, then review the ZIP and PIN shown for the parcel.
- Use the county GIS map to check the city line, parcel shape, nearby road, and adjacent PINs.
- Once the search narrows to a named road, use the Collinsville street directory for address-by-address work.
Ownership is not the same as occupancy. An assessor result supports the parcel-owner link and tax context. A dated directory or another suitable official record is needed before making a claim about who lived at the address.
Collinsville ZIP Search Fields
Madison DEVNET has more controls than a simple ZIP box. Search one group at a time. Begin with the site address, use the City and Zip Code fields to narrow it, then note the returned PIN. Broader sales or tax filters can pull unrelated properties and should not replace an exact address check.
| Portal field | Input type | Use | Format note |
|---|---|---|---|
| House Number Low / High | Number range | One address or a block | Use a narrow range first |
| Street Name | Text | Site-address match | Keep the source spelling |
| City / Zip Code | Text | Postal narrowing | Does not prove city limits |
| Parcel Number | Identifier | Exact parcel | Madison accepts 15 to 18 digits |
| Tax Year Low / High | Year range | Assessment history | Search All Tax Years is separate |
DEVNET also exposes owner, mailing address, sale price and date, document number, township, tax code, district, property class, and land-use filters. The portal publishes its update time but no index start year in the inspected material.
Collinsville ZIP+4 Labels Explained
Old routing material can confuse a Collinsville mailing search. Postal bulletins show labels such as 62281 and 62294 alongside Collinsville 62234. Research identifies those as ZIP+4 routing labels, not separate five-digit city codes. Do not add them as new Collinsville areas.
- ZIP code
- A five-digit USPS delivery code, such as the confirmed Collinsville code 62234.
- ZIP+4
- A five-digit code plus four added digits that narrow a delivery segment or route.
- PO-box ZIP
- A code reserved mainly for post-office boxes. None was confirmed for Collinsville in the inspected sources.
- Unique ZIP
- A code assigned to a single high-volume organization. None was confirmed here.
- Carrier route
- A postal delivery path within a ZIP, not a city or county boundary.
These terms describe postal handling. They do not verify a resident, owner, or legal jurisdiction.
ZIP Clues in Collinsville Deed Indexes
After county and parcel are known, the recorder index can connect the property to dated instruments. Madison land records begin in 1812. On the St. Clair side, a free AVA search provides index-only results by party, recorded date, parcel, document number, and document type. Tapestry EON and Laredo supply other remote routes, while public workstations remain an in-office fallback.
Review the St. Clair Recorder remote-access options before choosing an index or image service.
The captured page distinguishes the free index from paid image access. If a remote result is incomplete, use the recorder's public workstation or contact the office with a parcel or document number.
Collinsville ZIP Areas Versus ZCTAs
A Census ZIP Code Tabulation Area, or ZCTA, is a statistical shape built from the ZIP used by most addresses in each census block. The Census ZCTA guidance warns that it is not a USPS delivery boundary. It also cannot settle whether land lies inside Collinsville.
Use Census ZCTAs for population maps and broad comparisons. Use USPS for mail formatting. Use the Madison or St. Clair assessor and GIS for parcel placement, and city records for annexation or boundary changes. This source-by-source split keeps a statistical map from becoming a false address claim.
One More Illinois ZIP Clue
The Illinois Treasurer I-CASH search accepts a last or business name, first name, and optional city, ZIP, or property ID. The database is updated weekly. A match means unclaimed property may exist. It does not establish current residence or ownership of a Collinsville parcel.
The assigned image captures the state search fields used for a ZIP-assisted query.
Use the ZIP field only to narrow likely matches, then preserve the property ID and state source status. Never convert the city or ZIP shown in a claim result into a current-address assertion.
If I-CASH returns no match, do not treat that as proof that a person lacks a Collinsville connection. The state database serves unclaimed-property administration, not resident indexing. Try common name variants, omit optional location fields, and compare any result with a dated source. The city field can reflect the address held when property was reported, while the ZIP may be old or incomplete. Those limits make the state result a supporting lead, not the core of a Collinsville ZIP code directory.
Note: A Collinsville ZIP code directory narrows a search, but an official parcel, city file, or dated record must support the final claim.
