School districts in Louisiana
26% of the 535 populated ZIP Code areas in Louisiana are served by more than one school district — 141 of them, which puts the state 42nd among the fifty-two. It is organized into 69 unified districts, the largest being Jefferson Parish at 193,874 homes. Its most divided ZIP Code area, 70657, is split between 4 districts for elementary grades alone. The two districts that share the most ZIP Codes here are Lafourche Parish and Terrebonne Parish, in 5 of them. Counted by homes rather than by ZIP Code area, 28% of the state's housing sits in a ZIP Code that more than one district serves.
How often a ZIP Code here crosses a district line
The state sits well below the national rate of 53%. Jefferson Parish alone covers 193,874 homes, and districts that size swallow whole postal areas rather than splitting them. Where a ZIP Code area here does cross a line, it is worth checking precisely because it is unusual.

The largest districts in Louisiana
The top of the list is unusually flat: Jefferson Parish, Orleans Parish and East Baton Rouge Parish are within a few percent of each other at around 193,874 homes apiece. Where districts are evenly matched, no one of them owns a postal area, and the shares below tend to be split rather than lopsided.
The most divided ZIP Code area in Louisiana
ZIP Code area 70657 holds 2,324 homes and 4 districts take a real share of them for the early grades, but Beauregard Parish holds 77% on its own at that level. This is the shape that makes a single-name lookup look right: it names Beauregard Parish and describes most of the homes here, and silently not the rest.
Each percentage here is a share of the 2,324 homes counted in ZIP Code 70657, not the chance that any one address is in that district. Enrollment follows the street: two houses on opposite sides of the same road can be in different districts, and only the district office can say which.
Every track below is 35 cells long and stands for all 2,324 homes counted in ZIP Code 70657, so one cell is 66 homes, rounded to the nearest whole cell. Cells lit solid are the homes one district holds, and the unlit cells are the homes held by the other districts in the same list.
- Beauregard Parish School District1,793 of 2,324 homes77%
- Allen Parish School District317 of 2,324 homes14%
- Jefferson Davis Parish School District150 of 2,324 homes6.5%
- Calcasieu Parish School District64 of 2,324 homes2.8%
For grade school, an answer of one district name would be wrong for 531 of the 2,324 here.
Where a single district name still works in Louisiana
Across the 535 ZIP Code areas in Louisiana with homes in them, an answer of one district name misses 66,317 of the 2,072,850 homes they hold. That is 3.2% of the state, and in 383 of the areas one name covers everything: this is a state where the familiar answer is usually the right one, and the areas below are where it is not.
In ZIP Code 71203 · Monroe, Louisiana the largest district for grade school is Ouachita Parish, and naming it alone misses 5,345 of the 16,749 homes counted there. The rest are with Monroe City.
In ZIP Code 71202 · Monroe, Louisiana the largest district for grade school is Monroe City, and naming it alone misses 4,461 of the 10,638 homes counted there. The rest are with Ouachita Parish.

Where a ZIP Code here names more than one district
Of the 535 ZIP Code areas in Louisiana that the federal file names a district for, 141 name more than one school district. These are the 12 with the most, starting at 4 districts in one postal area: Beauregard Parish, Central and Zachary. Each row opens the full answer for that ZIP Code, with every district named for grade school and for high school and the share of the homes each one holds.

What to do next
Ask the district office to confirm your street address. A district settles that question on its own site: look for a school locator, a find my school tool, or an attendance zone map. Where there is none, ask the office itself.
A ZIP Code is a set of mail delivery routes, not a boundary: 141 of the 535 ZIP Code areas in Louisiana with a district named for them are served by more than one school district, and the line between two of them runs along streets. Only the district can say which side of that line an address is on.
This site links to no district website. None of the federal files it is built from publishes one, and a guessed address is worse than none. It is the district office, not a search engine, that settles an address.
If a house purchase depends on the answer, ask the district itself for written confirmation of that exact address. A listing is not a district record, and neither is this page.
What this cannot tell you
The homes were counted in the 2020 Census and the district lines are the 2026 boundary file. Nothing on this page adjusts one to the other. Where houses have been built or cleared since the count, a share here describes the place as it was counted rather than as it stands today, and in the fastest-growing ZIP Code areas that gap is the largest single source of error on this site.
A share on this page is a share of the homes in the ZIP Code area, not a probability for any particular address. Enrollment is decided by street address, and a district may run magnet, charter or choice programs that ignore the boundary entirely. If a decision depends on the answer, the district office is the only authority; this page shows what the federal boundary files say and when they were published.
A district boundary is not a school attendance zone. This site never says which school an address is assigned to: no current national dataset of attendance zones exists, and the district draws them itself. Nor is anything here endorsed or certified by the Census Bureau; we use their published files, and that is the whole of the relationship.
A ZIP Code is a set of mail delivery routes, not an area. What is mapped here is the Census Bureau's ZIP Code Tabulation Area, the closest published approximation to it. The two are not identical, and a handful of ZIP Codes used only for post office boxes or single buildings have no tabulation area at all.
Where these numbers come from
School district boundaries come from the Census Bureau's Census Geographic Relationship File, current 2026 vintage, which assigns every census block to a unified district or to an elementary and a secondary district. Homes and residents in each block come from the 2020 Census Redistricting Data (PL 94-171), H1_001 and P1_001. The ZIP Code areas come from the same Geographic Relationship File, block to ZIP Code Tabulation Area. District names and grade ranges come from the Census Gazetteer 2025, with 2020 for districts no longer listed.
The place name printed beside a ZIP Code comes from the Census 2020 ZIP Code Tabulation Area relationship files: place, county subdivision and county, taken 2026-09-06. It is a label rather than a measurement: the Census Bureau does not publish which post office a ZIP Code belongs to, so the place named is the one covering the most land inside the area, not the city the Postal Service prints on an envelope.
Everything else on this page — the shares, the counts of districts per ZIP, the comparison between the two grade bands, the rankings — is computed here from those files. The source publishes none of it. Snapshot taken 2026-09-03.
