What it returns
One directory of US public entities that are otherwise spread across federal datasets: counties, municipalities, townships, special districts, school districts, schools, libraries, police agencies, fire stations, hospitals, colleges, transit agencies, tribes, metropolitan planning organizations, public water systems and historical societies.
Search by name, type, state, county, city, federal ID or distance from a point, or list what sits inside a parent entity. Each row has its federal ID and ID system, parent entity, source, and whatever location and contact details the source has.
Coverage varies by type, so blanks are common: only some types have coordinates, phones or websites. Sources were last refreshed in October 2026. websiteGuessed marks a website we inferred rather than found in a source. Water systems leave out phone and street address.
Charged per entity returned.
