The ZIP Code areas it reaches

The spread is the thing to notice. In 37665 this district holds 97% of the homes; in 37659 it holds 1 home, 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

Kingsport City 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 10,582 of the 35,978 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.

Kingsport City holds 13,494 of the 20,106 homes in ZIP Code 37660 · Kingsport, Tennessee, so its name is right for most of the area and wrong for the rest: 6,566 homes with Sullivan County and 46 homes in a district too small to name here.

ZIP Code 37664 · Kingsport, Tennessee is a two-district area: 9,416 of its 13,299 homes are inside Kingsport City, and the other 3,883 homes are with Sullivan County. Which one an address belongs to is settled by the street, not by the five digits.

In ZIP Code 37665 · Kingsport, Tennessee the split runs 2,486 to 87 and the larger part is Kingsport City's: the rest is 87 homes with Sullivan County.

Kingsport City reaches into ZIP Code 37663 · Kingsport, Tennessee with 1,744 of its 6,431 homes; 3 districts there hold a real share of it, and Sullivan County leads them. The familiar answer for that area is one of the others, and it is wrong for those 1,744 homes.

Kingsport City is not the name anyone would give for ZIP Code 37617 · Blountville, Tennessee — Sullivan County leads it — and Kingsport City holds 88 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

Kingsport City 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 — Sullivan County, Washington County and Hawkins County School District. They are neighbors on the same postal ground, not the next stop for its own students.

• Hawkins County School District7,661 homes in 1 shared ZIP Code area

Who it shares ZIP Codes with

These districts appear alongside Kingsport City in the same ZIP Code areas: Sullivan County, Bristol City and Washington County. A single-name lookup for one of those areas has to choose between them, and the choice is right for some addresses and wrong for others.

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 7 ZIP Code areas Kingsport City 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.
