Verified Slidell ZIP Directory
Official evidence supports two current station-based codes and one additional Slidell-area code, while a fourth needs a fresh live check. That distinction matters. USPS station pages verify delivery services, Census ZCTAs describe statistical areas, and local documents can show a Slidell mailing label without proving the current USPS status of every address. The table keeps those levels of proof visible instead of merging them into one claim.
| ZIP Code | Areas Covered | Post Office | Notes |
|---|---|---|---|
| 70458 | Central Slidell delivery area | Slidell Post Office | Current USPS station and Census evidence; check each parcel |
| 70460 | West Slidell delivery area | West Slidell | Current USPS station evidence; not a city-limit map |
| 70461 | Slidell-associated ZCTA and local addresses | No station page captured | Official Census and local evidence; live USPS check still needed |
| 70459 | Historic Slidell postal grouping | Not verified as current | Do not treat as active without a fresh USPS result |
The archived USPS material grouped 70458, 70459, and 70461 under a Slidell label, but it separately linked 70462 to Springfield. No official capture supported adding 70469. A careful ZIP code directory records uncertainty rather than copying a broad web list. For a current address, the live USPS result controls the postal answer and the parish GIS controls the parcel answer.
Slidell ZIP Code Stations
The Slidell Post Office at 1950 2nd Street serves the verified 70458 label. Its published retail hours are 8 a.m. to 5 p.m. Monday through Friday and 9 a.m. to noon Saturday. The West Slidell station at 1897 Gause Boulevard West serves 70460, with weekday retail hours from 9 a.m. to 5 p.m. and the same Saturday window.
Those station addresses are strong postal checkpoints, but they do not draw the edge of Slidell. A station may serve mail beyond the municipality, and a legal city parcel may use a postal label that seems broader than the city. Save the result date when accuracy matters because station service and ZIP assignments can change.
Three Slidell Postal Searches
The USPS ZIP Code Lookup has three modes. Each answers a different question, and none confirms a person's identity. The address mode is best for one parcel; the city-and-state mode tests the set of codes associated with Slidell; and the cities-by-ZIP mode returns recognized place labels for one code.
| USPS mode | Fields | Use |
|---|---|---|
| By Address | Company optional, street, unit, city, state, ZIP | Normalize one mailing address |
| By City and State | City, state | Test the current Slidell ZIP list |
| Cities by ZIP | ZIP | Find accepted postal city names |
Use the address result as postal evidence only. The USPS disclaimer is explicit that its lookup does not confirm a person or company at the address.
Slidell ZIP Geography Is Layered
A ZIP code is a mail-delivery tool. The Census ZCTA is a statistical approximation, while the assessor parcel is a legal and tax-record unit. Slidell city limits are yet another layer. The alternate St. Tammany GIS viewer helps compare the parcel with surrounding geography.
Open the parish GIS source used for this boundary check before reviewing the captured interface.
The viewer image shows why a map-based check belongs beside, not inside, a postal conclusion. Keep postal city, legal municipality, parish, and ZIP in separate fields.
Note: Census counts describe groups and areas; they are not a directory of named Slidell residents.
Find Slidell Residents by ZIP
ZIP is most useful as a narrowing field. The Louisiana Voter Portal accepts it in both name and address routes, while assessor records may show it as part of a normalized physical or mailing address. Neither source turns a ZIP into a complete resident list. Pair the code with the smallest lawful set of facts needed for the search.
- Verify the full address or Slidell city label with USPS, and save the access date.
- Check the physical address in the Assessor search, keeping its mailing address separate from its situs, or physical, location.
- Use the voter name route with first name, last name, ZIP, and birth month/year when those facts are lawfully known.
- Use the voter address route with ZIP, street address, apt/lot, and city for a current-registration check.
- Confirm jurisdiction in GIS, then move to the Slidell street directory only when the task becomes street-specific.
Open the official voter address lookup to see the ZIP-first form represented in the capture below.
The form reinforces the main rule: ZIP works with an address and city. A result reflects registration status, not proof of current occupancy.
Slidell ZIP Search Fields
The official sources expose different fields because they answer different questions. Record the selected roll year in the assessor, the result date in USPS, and the registration context in the voter portal. A mailing address may be where a tax bill goes rather than where the parcel sits.
| Source | ZIP role | Other key fields | Limit |
|---|---|---|---|
| USPS | Result or input | Street, unit, city, state | Delivery geography only |
| Voter name | Narrows a name | First/last name, birth month/year | Current registration context |
| Voter address | Required input | Address, apt/lot, city | Not occupancy proof |
| Assessor | Part of address | Owner, situs, mailing address, year | Parcel and roll context |
The free voter search differs from a purchased voter-file extract. The Secretary of State purchase process uses defined selections, an estimate, advance payment, and electronic delivery. It should not be treated as an instant public download.
For an older or inactive registration question, the St. Tammany Registrar offers another access channel. Its Slidell Towers counter is on the second floor at 520 Old Spanish Trail, with phone 646-4125. The registrar may provide copies of registration applications with required redactions. Define the date range and ask the office to remove protected declination, agency, and identifying fields. The statewide purchase route can deliver PDF or tab-delimited output after the requester selects criteria and pays the estimate, but its file date and district selection must travel with any conclusion.
Property searches also have an offline fallback. The Assessor's Slidell Towers office, reached at 985-646-1990, can help when a street suffix, parcel split, care-of line, or old assessment number defeats the web form. Staff may search owner name, physical address, mailing address, property description, or assessment number. Save the chosen assessment year because the roll and GIS can update on different schedules.
ZIP Labels and Slidell Places
Community names add useful context but still do not define postal or city limits. Lake Village describes itself as east of Slidell and north of Gause, while Old River Road materials name Bay Ridge, Quail Ridge, Quail Valley, and The Settlement. These names can appear in parcel descriptions, local pages, and address searches.
Visit Lake Village's public participation source before using the captured page as a geographic clue.
The association page helps place a community name. It does not supply a ZIP boundary or permission to republish a private directory.
When a community label appears in a deed or local document, carry it into the assessor's property-description search and the Clerk's map index. A subdivision can cross a delivery line, and one delivery area can contain several civic or historic place names. The code narrows the search, while the legal description identifies the land.
Slidell ZIPs Versus City Limits
A Slidell postal label does not prove that a parcel is within the incorporated city. Confirm delivery geography through USPS, then use the Assessor GIS and city or parish records for legal jurisdiction. This split is especially important when a record custodian sits in Covington, the parish seat, even though the searched address carries Slidell in its mailing line.
- ZIP and ZIP+4
- A five-digit delivery area versus the added four digits that narrow a delivery segment.
- PO-box ZIP
- A code used for post-office boxes rather than a map of household parcels.
- Unique ZIP
- A code assigned to one large recipient; none was verified for Slidell in the research.
- Carrier route
- A postal delivery path inside a ZIP, not a legal neighborhood boundary.
Keep both answers. Store the postal city and ZIP separately from the legal municipality and parish, then cite the source and date for each.
Historical searches need one more column for the address exactly as printed. An older ward, bayou, subdivision, or post-office label should not be silently changed to a modern Slidell street. Record a proposed modern match beside it and show the evidence for the match. This preserves the clue if the current parcel search fails.
The Assessor's online search, GIS, Slidell Towers counter, and the Clerk's online, counter, mail, and Archives channels cover different parts of that work. A missing web result should lead to the office that holds the older series. It should not lead to a claim that the address or resident never existed.
