The most divided ZIP Code area in Alabama
ZIP Code area 35022 holds 9,956 homes, and 5 districts each take a meaningful share of them for elementary grades — Jefferson County first at 55%, then Bessemer City. A lookup that names the first is describing that share of the homes and silently not the 4,512 homes that remain.
Each percentage here is a share of the 9,956 homes counted in ZIP Code 35022, 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 9,956 homes counted in ZIP Code 35022, so one cell is 284 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.

- Shelby County School District255 of 9,956 homes2.6%
- Birmingham City School District232 of 9,956 homes2.3%
- Hoover City School District60 of 9,956 homes0.6%
For grade school, an answer of one district name would be wrong for 4,512 of the 9,956 here.
How much of Alabama a single district name misses

ZIP Code 35216 · Vestavia Hills, Alabama names 5 districts. Hoover City is the largest of them for grade school, and an answer of its name alone misses 9,809 of the 17,391 homes there; Vestavia Hills City, Jefferson County and Homewood City hold the rest.

In ZIP Code 35215 · Birmingham, Alabama the largest district for grade school is Jefferson County, and naming it alone misses 8,780 of the 20,014 homes counted there. The rest are with Birmingham City.

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: 332 of the 648 ZIP Code areas in Alabama 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.
