The ZIP Code areas it reaches

The spread is the thing to notice. In 83686 this district holds 96% of the homes; in 83607 it holds 2 homes, under half a percent. Same district, opposite answers, and a lookup that names it without the share tells the second household the same thing as the first.

What one name misses in the areas it leads

Nampa School District 131 is the largest district in 3 ZIP Code areas, and not one of them is wholly its own. Answer with its name alone and the answer misses 10,589 of the 45,527 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.

Nampa School District 131 is one of 4 districts the file names for ZIP Code 83687 · Nampa, Idaho at that level. It holds 7,197 of the 13,006 homes there; the rest is 5,809 homes with Vallivue School District 139, Kuna Joint School District 3 and Meridian Joint School District 2. One name for that area is not a simplification, it is a different answer for 5,809 of the homes in it.

ZIP Code 83651 · Nampa, Idaho is a two-district area: 8,808 of its 12,885 homes are inside Nampa School District 131, and the other 4,077 homes are with Vallivue School District 139. Which one an address belongs to is settled by the street, not by the five digits.

Nampa School District 131 holds 18,933 of the 19,636 homes in ZIP Code 83686 · Nampa, Idaho, so its name is right for most of the area and wrong for the rest: 699 homes with Kuna Joint School District 3 and Vallivue School District 139; 4 homes in a district too small to name here.

Nampa School District 131 is not the name anyone would give for ZIP Code 83641 · Melba, Idaho — Melba Joint School District 136 leads it — and Nampa School District 131 holds 16 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 4 of the 5 ZIP Code areas Nampa School District 131 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.
