The ZIP Code areas it reaches

The spread is the thing to notice. In 78240 this district holds 100% of the homes; in 78242 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.

The areas it leads without holding most of the homes

Northside Independent is the largest district in 16 ZIP Code areas. Answer with its name alone and the answer misses 31,335 of the 294,644 homes those areas hold — though in 9 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

Northside Independent is the largest name in ZIP Code 78228 · San Antonio, Texas and still holds a minority of it: 8,813 of 20,782 homes. The other 11,969 homes are with San Antonio Independent and Edgewood Independent. This is the shape that makes a one-name answer worst — the name is right for fewer homes than it is wrong for.

Northside Independent holds 23,619 of the 31,697 homes in ZIP Code 78245 · San Antonio, Texas, so its name is right for most of the area and wrong for the rest: 8,078 homes with Southwest Independent and Medina Valley Independent.

ZIP Code 78230 · San Antonio, Texas is a two-district area: 16,533 of its 21,014 homes are inside Northside Independent, and the other 4,481 homes are with North East Independent. Which one an address belongs to is settled by the street, not by the five digits.

Northside Independent is not the name anyone would give for ZIP Code 78258 · San Antonio, Texas — North East Independent leads it — and Northside Independent holds 918 homes there all the same. Answer that area with one name and that is what it is wrong about.

Have a street address?

A ZIP Code names every district that can serve the area; a street address settles which one serves a home. The Census Bureau geocoder takes an exact address and returns its school districts from the current boundary files, free and with no account.

What to do next

Ask the district office to confirm your street address: look on its site for a school locator, a find my school tool or an attendance zone map, or call the office.

A ZIP Code is a set of mail delivery routes, not a boundary: in 14 of the 25 ZIP Code areas Northside Independent 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.

District websites and phone numbers here come from the NCES Common Core of Data directory, 2024-25 school year, filed under the same district ID as the Census boundary files. Where it lists no usable website, none is printed rather than guessed.

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.

Where these numbers come from

The homes were counted in the 2020 Census and the district lines are the 2026 boundary file, so a fast-growing area may have changed since; ZIP Codes here are the Census Bureau's ZIP Code Tabulation Areas; a share is a share of homes, not the chance that one address is in a district; and a district is not a school attendance zone. Every source, file and caveat is on the method page.
