The ZIP Code areas it reaches

The spread is the thing to notice. In 01776 this district holds 98% of the homes; in 01778 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.

• ZIP Code 01731 · Hanscom AFB, Massachusetts98% of the homes

What one name misses, and what changes later

Lincoln-Sudbury is the largest district in 3 ZIP Code areas, and not one of them is wholly its own for high school. Answer with its name alone and the high school answer misses 241 of the 9,362 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.

ZIP Code 01776 · Sudbury, Massachusetts is a two-district area for high school: 6,402 of its 6,556 homes are inside Lincoln-Sudbury, and the other 154 homes are with Wayland. Which one an address belongs to is settled by the street, not by the five digits.

Lincoln-Sudbury holds 2,284 of the 2,360 homes in ZIP Code 01773 · Waltham, Massachusetts, so its name is the right high school answer for most of the area and the wrong one for the rest: 68 homes with Concord-Carlisle and 8 homes in a district too small to name here.

In ZIP Code 01731 · Hanscom AFB, Massachusetts the split runs 435 to 11 and the larger part is Lincoln-Sudbury's: the rest is 11 homes with Bedford and Lexington.

The elementary districts that feed it

Students arrive at Lincoln-Sudbury from 3 districts that run the lower grades in the same ZIP Code areas — Sudbury, which sends 70%, Lincoln, which sends 29% and Concord, which sends 0.7%. An address on that ground belongs to two districts at once, one for grade school and this one for high school, and neither name is the whole answer.

• Lincoln School District29% of Lincoln-Sudbury's homes come from here
• Concord School District0.7% of Lincoln-Sudbury's homes come from here

This list is an estimate, names as well as percentages. The snapshot behind this site keeps the homes each district holds in each ZIP Code area, not the pair of districts on each census block, so a district is listed here when it runs the other band in a ZIP Code area this one shares, and each percentage spreads that area's homes across those districts in proportion to the share each holds there. Unified districts are left out: a block in a unified district belongs to no elementary or secondary district. Read the percentages as the size of the crossing, not as a count of houses.

Have a street address?

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 3 of the 4 ZIP Code areas Lincoln-Sudbury 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.
