Belleville ZIP Directory Coverage
The official material supports a set of Belleville-associated postal codes, but not a claim that every address in each code is inside the city. The principal Post Office is at 120 W. Washington Street. Dutch Hollow is another Belleville-labeled postal location, while a current USPS listing places 62269 at the O'Fallon Post Office. The table therefore describes postal evidence and the check each code still needs.
| ZIP Code | Areas Covered | Post Office | Notes |
|---|---|---|---|
| 62220 | Principal Belleville delivery label | Belleville, W. Washington Street | Delivery area is not a city polygon. |
| 62221 | Belleville-associated delivery area | Verify by exact address | Check street and municipality. |
| 62222 | Associated or PO-box designation | Verify current use | Does not prove a site lies in Belleville. |
| 62223 | Belleville label and nearby service area | Dutch Hollow listing | Confirm the parcel municipality. |
| 62225 | Older Belleville association | Current station varies by address | Use current USPS results. |
| 62226 | Belleville-associated delivery area | Verify by exact address | May extend past corporate limits. |
| 62243 | Older Belleville-routed association | Verify by exact address | Routing is not city geography. |
| 62269 | Nearby or older overlapping association | O'Fallon Post Office | Never classify as Belleville from code alone. |
| 62285 | Historical administrative association | Verify current station | Not a city-limit assertion. |
This Belleville postal directory treats 62220, 62221, 62222, 62223, and 62226 as the core useful set, then labels the remaining codes as associated or historical. USPS routing documents also mention 62225 and 62243. An older Illinois Commerce Commission list adds 62269 and 62285. Age and purpose matter: an administrative list can preserve an association that does not match today's Post Office or a city boundary.
Verify a Belleville Postal Address
Enter the complete address in the USPS ZIP Code Lookup. A valid result establishes the postal form used for delivery. It does not establish the city government responsible for the parcel, nor does it show who lives there. Copy the standardized street spelling, directional word, unit, city label, and delivery code before using other records.
The Belleville Post Office entry uses 62220-9998 at 120 W. Washington Street. Dutch Hollow uses a Belleville label at 5731 Mt. Pleasant Lane with 62223-9998. The O'Fallon Post Office listing uses 62269-9998. These station examples show why the code and postal city must be read together rather than treated as a municipal boundary.
Note: USPS answers a mail-routing question; use the county parcel municipality field when the question is whether a site lies in Belleville.
Find Belleville Residents by ZIP
No inspected official portal offers a clean, public, citywide resident list filtered only by ZIP. The Belleville postal directory instead uses a code as a narrowing value. The county GIS carries ZIP attributes, the Illinois voter check requires a ZIP plus personal and street details, and the Assessor's mobile-home form has site city fields. Recorder AVA works from a name, document, date, or parcel rather than ZIP.
- Verify the full address and current delivery code with USPS.
- Open the St. Clair County GIS Parcel Map Viewer and locate the address or parcel.
- Read the municipality, site, owner, mailing, district, and ZIP attributes as separate fields.
- Use the county Assessor search to check the parcel record, while remembering an owner's mailing address is not proof of occupancy.
- For an individual registration check, supply the required name, birth date, ZIP, street number, and street name to the official voter lookup.
Once the code has narrowed the area, the Belleville street directory explains the more precise street and parcel route. Keep the original ZIP source and its date. A historical directory's printed postal form should not be silently replaced with today's standardized form.
Belleville ZIP Search Fields
Each official system asks a different question. That determines which fields are required and what its result can prove.
| Official tool | ZIP-related input | Other required input | What it settles |
|---|---|---|---|
| USPS address lookup | Returned from the address | Street, city, and state | Current delivery format |
| Illinois voter lookup | Five-digit ZIP required | First and last name, birth date, then street number and name | Individual registration check |
| County GIS parcel layer | ZIP stored as an attribute | Address, parcel, or map selection | Parcel context and municipality fields |
| Assessor mobile-home search | No general ZIP-only search | Site city and other form values | Tax and parcel record |
| Recorder AVA | No ZIP search | Party, date, document, or parcel | Recorded-document index lead |
The limitation is useful. A portal that does not accept ZIP cannot support a claim that it returned every person in that postal area. Use the code for scope, then use the record's own search key.
Belleville ZIP and License Records
A professional credential may include a public location field, but its scope differs from a resident roll. The Illinois Department of Financial and Professional Regulation lookup searches credentials and can return a location, credential number and type, status, dates, and discipline information. It excludes home address, email, and phone details.
Open the official IDFPR license lookup shown here when a Belleville name or business address needs a credential check.
The captured screen confirms that this is a state credential search, not a list of everyone in a Belleville ZIP. Treat any displayed address as the location attached to that license record and preserve its status date.
Older Belleville ZIP Labels
Historical research should preserve the address as printed. Belleville was founded as the county-seat center in 1814, West Belleville was platted in the 1830s, and the city incorporated West Belleville in 1882. Later annexation policy and so-called donut holes created more reasons that a Belleville postal label and Belleville corporate status may diverge.
The official digital directory description says streets are arranged alphabetically and numbers numerically, with householders and concerns shown opposite. That street form is the proper key for an old edition. No authoritative citywide street-renaming or number-conversion table was found. If the old and current address differ, keep both forms and ask the City Clerk, GIS staff, library archive, or Historical Society about the specific block.
Belleville ZIPs Versus City Limits
A ZIP boundary serves mail delivery. Belleville's corporate line controls municipal jurisdiction. St. Clair County parcel records add still other fields, such as township, situs address, owner mailing address, and municipality. One parcel can therefore display several place labels without contradiction. The mistake is choosing one field and treating it as proof of where a person lives.
- ZIP Code
- A five-digit USPS delivery area. Its edge need not match a city line.
- ZIP+4
- A delivery refinement for a smaller segment, such as one side of a block or a group of boxes.
- PO-box ZIP
- A code or designation used chiefly for Post Office boxes rather than a map of homes.
- Unique ZIP
- A code assigned to one high-volume recipient. No Belleville example was confirmed in the research.
- Carrier route
- The sequence used to deliver mail. It is an operational route, not a resident boundary.
Belleville District and Ward Clues
Belleville's geography includes Public Square, East and West Belleville, the Old Belleville, Hexenbuckel, and Oakland historic districts, and eight council wards described by street boundaries. A code may narrow the search area, but those local layers can identify the correct records office or meeting record more precisely.
The GIS parcel layer is the bridge between postal and civic geography. Search an address, click the parcel, and retain its municipality and district attributes. Do not use a historic district name as proof of a resident's identity. Likewise, the 1884 Sanborn set has 14 sheets and can show building footprints or old street context, but it needs a directory or deed to name an occupant.
Note: Keep the house number, street direction, municipality, township, and ZIP in separate columns when comparing records.
Confirm Belleville ZIP Directory Results
A defensible ZIP-based result shows its limits. Cite the USPS result for delivery, the GIS record for parcel geography, and the source date for any name. If the sources disagree, do not blend them. A tax-bill mailing address may belong to an owner who lives elsewhere, and a professional credential address may identify a practice or office.
For a difficult boundary question, contact the City Clerk or county GIS office with the exact parcel and street address. The Illinois voter registration lookup is an individual validation sequence, not a downloadable public roster. State voter files have purpose limits, and protected addresses may be withheld or substituted. An absent address may therefore be intentional.
The Belleville postal directory is most reliable as a narrowing tool. It helps select the next official record while guarding against the common myth that a postal city equals city-limit residency.
Save the date of each result. Postal assignments, parcel fields, and agency interfaces can change. When documenting family or property history, quote the older address exactly before adding a current standardized version in a separate field. That method keeps a later postal update from altering what the original directory, deed, or newspaper actually said. It also makes conflicting Belleville and nearby-place labels much easier for another researcher to audit.
