What county am I in?

The county under your feet from real boundary data, with its FIPS code.

Free, no signup. Your location is used for one lookup and never stored.

THE API UNDERNEATH

GET /point?lat=25.77&lon=-80.19

Coordinates in, facts out: the county comes from a point-in-polygon test against real administrative boundaries, not a ZIP approximation, with state, country, and elevation on the same response. Same endpoint on every plan, one pooled request per lookup.

Point APICounty by ZIP

QUESTIONS

How is this different from county by ZIP?
A ZIP is a mail route and can cross county lines. This answer comes from a point-in-polygon test against real county boundaries at your exact coordinates.
Do you store my location?
No. The coordinates make one lookup and are not saved. The page never asks until you tap the button.
Does it work outside the US?
France and Great Britain answer at the same layer, departments and districts. Elsewhere the district is an honest null while country and state still answer.
Can I do this from code?
Yes. GET /point?lat=&lon= returns country, state, county, and elevation for any coordinates. One pooled request per lookup.
