Lamar County School District

It never has a ZIP Code to itself

The counts below come from the census blocks assigned to Lamar County, grouped by the ZIP Code area each block falls in. The Census Bureau publishes the blocks; the grouping is computed here, and it is the only place these particular numbers exist.

The ZIP Code areas it reaches

The spread is the thing to notice. In 39475 this district holds 97% of the homes; in 39470 it holds no homes at all. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

• ZIP Code 39475 · Purvis, Mississippi97% of the homes
• ZIP Code 39482 · Sumrall, Mississippi85% of the homes
• ZIP Code 39455 · Lumberton, Mississippi80% of the homes
• ZIP Code 39402 · Hattiesburg, Mississippi73% of the homes
• ZIP Code 39429 · Columbia, Mississippi0.9% of the homes

What one name misses in the areas it leads

Lamar County is the largest district in 4 ZIP Code areas, and not one of them is wholly its own. Answer with its name alone and the answer misses 6,888 of the 33,733 homes those areas hold. That count is computed here from census blocks; the lookups that answer this question with a single name never print it.

Lamar County holds 14,399 of the 19,622 homes in ZIP Code 39402 · Hattiesburg, Mississippi, so its name is right for most of the area and wrong for the rest: 5,199 homes with Hattiesburg Public and Forrest County Schools and 24 homes in a district too small to name here.

Lamar County is one of 5 districts the file names for ZIP Code 39455 · Lumberton, Mississippi at that level. It holds 3,440 of the 4,300 homes there; the rest is 842 homes with Forrest County Schools, Poplarville Separate and Stone County and 18 homes in a district too small to name here. One name for that area is not a simplification, it is a different answer for 860 of the homes in it.

ZIP Code 39482 · Sumrall, Mississippi repeats the pattern with 4 names holding a real share: 3,802 of its 4,454 homes are Lamar County's, and the other 652 are not.

ZIP Code 39475 · Purvis, Mississippi is a two-district area: 5,204 of its 5,357 homes are inside Lamar County, and the other 153 homes are with Forrest County Schools. Which one an address belongs to is settled by the street, not by the five digits.

Lamar County is not the name anyone would give for ZIP Code 39429 · Columbia, Mississippi — Columbia leads it — and Lamar County holds 67 homes there all the same. Answer that area with one name and that is what it is wrong about.

Who takes the other homes in its ZIP Codes

Lamar County runs pre-K through grade 12 itself, so an address it holds sees no change of authority between grade school and high school. The districts listed below are the ones that take the other homes in the ZIP Code areas it shares — Poplarville Separate, Columbia and Hattiesburg Public. They are neighbors on the same postal ground, not the next stop for its own students.

• Poplarville Separate School District5,608 homes in 2 shared ZIP Code areas
• Columbia School District4,424 homes in 1 shared ZIP Code area
• Hattiesburg Public School District3,551 homes in 1 shared ZIP Code area
• Marion County School District2,997 homes in 2 shared ZIP Code areas
• Forrest County Schools2,134 homes in 3 shared ZIP Code areas
• Covington County School District263 homes in 1 shared ZIP Code area

Who it shares ZIP Codes with

Lamar County shares ZIP Code areas with 8 different districts. The most frequent are Forrest County Schools, Marion County, Columbia and Covington County. In a neighborhood this crowded the question is not which district serves the ZIP Code but which side of which street an address is on.

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: in 5 of the 6 ZIP Code areas Lamar County reaches, at least one other district holds a real share of the homes as well, and the line between 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.
