Houston Independent School District

Texas · runs pre-K through grade 12

NCES ID 4823640 · houstonisd.org · (713) 556-6005

Houston Independent covers 658,539 of the homes in 71 ZIP Code areas, but its smallest measured presence is a different thing entirely: in ZIP Code area 77079 it holds 128 of 16,124 homes, or 0.8% of them. An address in that ZIP Code is almost certainly not in this district, and a lookup that names the district without the share says the opposite. Below the half-percent line this page draws it reaches 2 further ZIP Code areas, the least of them no homes at all in 77044.

A few homes at the edge of someone else's ZIP Code

At 1,995 homes to the square mile this is city territory, and district lines in a city follow streets. Houston Independent covers 330 square miles in all — small enough that a single ZIP Code area can hold most of it, and several ZIP Codes can cut across it.

What an answer of one district name misses here

Houston Independent is the largest district in 55 ZIP Code areas. Answer with its name alone and the answer misses 19,513 of the 638,233 homes those areas hold — though in 43 of them it holds every home there is. The count is homes, not addresses, and it is the number no lookup prints.

ZIP Code 77091 · Houston, Texas is a two-district area: 5,852 of its 11,439 homes are inside Houston Independent, and the other 5,587 homes are with Aldine Independent. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 77093 · Houston, Texas the split runs 9,233 to 5,384 and the larger part is Houston Independent's: the rest is 5,384 homes with Aldine Independent.

Houston Independent holds 13,061 of the 15,024 homes in ZIP Code 77092 · Houston, Texas, so its name is right for most of the area and wrong for the rest: 1,918 homes with Cypress-Fairbanks Independent and Aldine Independent; 45 homes in a district too small to name here.

In ZIP Code 77063 · Houston, Texas the split runs 19,629 to 1,077 and the larger part is Houston Independent's: the rest is 1,045 homes with Alief Independent and 32 homes in a district too small to name here.

In ZIP Code 77002 · Houston, Texas the single-name answer is the true one: Houston Independent holds all 8,412 homes counted there, and no other district holds a share worth naming.

ZIP Code 77036 · Houston, Texas is close to being two districts in equal parts: Houston Independent holds 13,567 of its 30,733 homes and Alief Independent leads the rest. A lookup that picks the larger name is making a coin-toss look like a fact.

ZIP Code 77042 · Houston, Texas is another area where Houston Independent is present without being the answer: 10,214 of its 21,770 homes, behind Alief Independent.

Houston Independent reaches into ZIP Code 77075 · Houston, Texas with 4,045 of its 12,555 homes, behind Pasadena Independent. The familiar answer for that area is the other name, and it is wrong for those 4,045 homes.

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 24 of the 71 ZIP Code areas Houston 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.
