Why this exists

For batch operations across an asset list, a vendor list, or a customer database, getting lat/lon coordinates from a free address geocoder is the building block. Pair with the Country Profile and EPA ECHO tools for facility-by-facility diligence.

Frequently asked questions

What does Address & Place Geocoder do?

Forward and reverse geocoding via OpenStreetMap Nominatim. Forward: paste an address, ZIP, or place name → get lat/lon coordinates and structured address parts. Reverse: paste coordinates → get the named location. Sourced from OpenStreetMap's community data.

Is OpenStreetMap reliable for geocoding?

For populated areas in the U.S., Europe, and most developed regions — yes, comparable to Google or Apple. For remote areas, less developed regions, and informal addressing systems, OpenStreetMap can be sparser. For high-volume commercial use, host your own Nominatim or use a paid tier.

What's the rate limit?

OpenStreetMap Foundation's usage policy is 1 request per second per user. The tool fires one request per submit; rapid-fire searches may hit 403. The free service is best for occasional lookups, not bulk geocoding.
