Turn an address into coordinates.

How it works

Type a US address and the geocoder returns a latitude and longitude, the standardised address it matched, and an accuracy_type that tells you whether the point is a rooftop address point, a position interpolated along the street's house-number range, or the centroid of a ZIP, place or county. Rooftop points come from the National Address Database; street ranges from TIGER/Line.

In your code

curl "https://api.geocode.net/v1/geocode?q=1600+Pennsylvania+Ave+NW+Washington+DC" \
  -H "X-API-Key: YOUR_KEY"

{ "results": [ { "formatted": "1600 Pennsylvania Ave NW, Washington, DC 20500",
                 "location": { "lat": 38.897675, "lng": -77.036545 },
                 "accuracy": 1.0, "accuracy_type": "rooftop", "source": "nad" } ] }

Send street, city, state and postal_code separately if you already have them split, and add fields= to append Census, district, school or time zone data in the same call.

Notes

• One unit per lookup. Free keys get 10,000 a month; this page uses a shared demo key with a per-minute limit.
• Results are yours to store indefinitely. The index is built from public-domain data.
• Have a whole file of addresses? The spreadsheet geocoder does them in batches in your browser.
