Caddo Parish ZIP Coverage
The official Louisiana service-area list used in the research contains 47 ZIP codes associated with Caddo Parish. It is an administrative coverage list, not a postal boundary file. The older Louisiana Library directory supplies community and post-office associations for many outlying codes. Exact delivery for one address still belongs to USPS.
| ZIP Code | Areas Covered | Post Office | Notes |
|---|---|---|---|
| 71004 | Belcher | Belcher | Physical community and service-list code |
| 71009 | Blanchard; Dixie | Blanchard | Two community names in the historical list |
| 71033 | Greenwood | Greenwood | Physical community |
| 71044 | Ida; Mira | Ida | Mira appears under Ida |
| 71047 | Keithville; Spring Ridge | Keithville | Spring Ridge appears under Keithville |
| 71060 | Mooringsport | Mooringsport | Physical community |
| 71061 | Oil City; Caddo | Oil City | Oil-region name overlap |
| 71069 | Rodessa; Zylks | Rodessa | Zylks appears under Rodessa |
| 71082 | Vivian; Trees | Vivian | Trees appears under Vivian |
| 71101 | Downtown Shreveport example | Shreveport | Verify station and street with USPS |
| 71102 | Shreveport plus six historic community names | Shreveport last line | Not one neighborhood boundary |
| 71106 | Shreveport; Forbing | Shreveport | Forbing appears under this code |
| 71115 | Shreveport; Caspiana association | Verify current last line | Historical community association |
| 71130 to 71166 selected codes | Shreveport special-use range | Shreveport postal system | Exact delivery category not established |
Other confirmed outlying codes include Bethany 71007, Gilliam 71029, Hosston 71043, and additional Shreveport delivery codes from 71103 through 71129. Static sources did not prove which later 711xx entries are carrier, post-office-box, or unique codes. The Caddo Parish ZIP code directory therefore marks those categories for address-level verification rather than guessing.
Caddo Parish ZIP Communities
The strongest local ZIP quirk is the 71102 cluster. A historical community list places Cecile, Flournoy, Gayles, Lachute, Lucas, and Robson under the Shreveport 71102 last line. That does not make all six places one downtown neighborhood. It shows how postal labels can compress local geography.
Similar pairings appear elsewhere: Forbing under 71106, Caspiana under 71115, Spring Ridge under Keithville 71047, and Zylks under Rodessa 71069. Search both the community name and postal last line in old directories, newspapers, deeds, and archive catalogs. This matters most when a family used a place name that no longer appears in a current mailing format.
Note: A community association from an older state list should be checked against current USPS data before mailing or drawing a boundary.
Verify Caddo Parish ZIP Codes
The USPS ZIP Code Lookup is the final authority for a current street address or city-and-state query.
The search should be run with the complete number, street, unit, city, and state. Preserve the result date because delivery assignments can change.
The USPS explanation of ZIP geography states that ZIP boundaries need not follow municipal lines.
That distinction explains why the Caddo Parish ZIP code directory cannot be read as a city-limit map or proof that an address is governed by Shreveport.
Search Caddo Parish by ZIP
Only use a ZIP field when the official portal actually provides it. Louisiana’s voter portal accepts a ZIP in both its person and address paths. The Caddo Assessor advertises owner, Section-Township-Range, and subdivision searches, but the public page did not verify a ZIP-wide filter. The parish GIS request form asks for the requester’s ZIP, which is not a parcel-search control.
- Verify the complete current address through USPS and record its returned last line.
- Use the Louisiana voter address path with street, ZIP, city, and apartment or lot when applicable.
- For voter-file research beyond one portal result, follow the Secretary of State request rules and permitted-use terms.
- Use the assessor’s verified owner or subdivision modes, not an unconfirmed ZIP filter.
- Move from the postal area to a named street only after the boundary and record purpose are clear.
A ZIP match narrows a search; it does not establish who lives at a parcel. For the address and parcel chain after the postal check, use the Caddo Parish street directory. Keep a mailing address separate from the property’s situs address, meaning the physical location recorded by the assessor.
Caddo Parish ZIP Search Fields
The Louisiana Voter Portal uses ZIP as one part of a controlled lookup. It does not publish an open parish household list. Its disclaimer says public voter and address records are kept separate to protect registrants, and protected fields are excluded.
| Portal route | ZIP field | Other verified inputs | What it does not prove |
|---|---|---|---|
| Voter by name | ZIP accepted | Name and birth month/year | Every resident at the ZIP |
| Voter by address | ZIP accepted | Address, city, apartment or lot | Ownership or parcel limits |
| Caddo Assessor | Not verified | Owner, subdivision, Section-Township-Range advertised | ZIP-wide resident list |
| GIS map request | Requester contact only | Map layers, size, copies, boundary description | Public ZIP search mode |
Open the official voter address lookup to see the address-oriented path.
The screen shows why ZIP works as a confirming field beside a full address, not as a stand-alone directory of Caddo Parish residents.
Historic Caddo Parish ZIP Clues
Modern ZIP codes began long after many Caddo Parish family records. The USPS Postmaster Finder accepts a three-digit ZIP prefix and warns that historic post offices may have been discontinued.
The historical office list can connect an old place name to a postal route. It should be paired with city directories, maps, deeds, or tax rolls because a former post office is not a current delivery boundary.
Oil-country names need special care. Parish history places the oil boom around 1904 through 1914 and ties it to Oil City and the Caddo Lake region. Search Oil City, Caddo, Mooringsport, and Caddo Lake separately in historical sources before accepting one geographic match.
Caddo Parish ZIPs Versus Cities
Caddo Parish has eleven municipalities, but its postal system does not form eleven matching shapes. Shreveport is the parish seat and dominant postal last line. Belcher, Blanchard, Gilliam, Greenwood, Hosston, Ida, Mooringsport, Oil City, Rodessa, and Vivian have separate municipal identities, while other community names may sit beneath those postal lines.
City, parish, precinct, parcel, service-area, and ZIP boundaries answer different questions. A 71102 address can carry Shreveport in the mail without proving that an older community name vanished or that every public service comes from the city. A voter precinct cannot be inferred from the ZIP. Property jurisdiction should be checked through the assessor and legal description.
- ZIP and ZIP+4
- The five-digit delivery area and a more precise four-digit add-on for a smaller delivery segment.
- PO-box ZIP
- A code used for post-office boxes rather than a broad street-delivery area.
- Unique ZIP
- A code assigned to one large recipient or institution. No specific Caddo unique-code assignment was proven.
- Carrier route
- A postal delivery path inside a ZIP, not a municipal or parcel boundary.
Caddo Parish ZIP Addressing
Caddo Public Works issues municipal 9-1-1 addresses and handles subdivision, oil and gas, culvert, and road-crossing permits. Its address approval route is online-only, with questions directed to 318-226-6949. That work establishes a local emergency or situs address. USPS then determines the mailing form and ZIP.
The parish GIS office maintains parcels and street centerlines but says it does not provide GIS data directly to the public. Map requests go through a specified production form, NLCOG, or the Assessor. A ZIP entered on that form identifies the requester’s contact address; it is not a search filter for every parcel within a postal zone.
When an old house number disappears, compare its deed legal description, historical map, city directory street index, and archive material. No official dated Caddo renumbering schedule was found. A clean modern postal result cannot by itself resolve an old address.
