State and county for a coordinate, with Census GEOIDs. Free - answered from boundaries the platform ingests and holds, with no provider call. Point-in-polygon against Census TIGER/Line boundaries (§22.2). Returns the administrative areas containing the point, most specific first, each with the GEOID that every other census dataset is keyed by. Tract, ZCTA and place follow when those layers are ingested. A coordinate exactly on a county line is genuinely in both counties and both are returned - the alternative is an address falling into a gap. Take the first if you need one answer. When to use: Use to turn a coordinate into a county or state GEOID before asking for any census-keyed data. Free, so there is no reason to guess a FIPS code. This tool is free and does not consume plan credits. Every response includes a sources[] array naming the data origin and licence.
