Questions developers ask

What does reverse geocoding return?

The nearest available US address or place label for a latitude/longitude pair, as a formatted address plus structured components, with the distance in meters from your point to the match. Where no address is close, the answer can be a road name only, with no house number, city or ZIP.

How close is the matched address?

The response includes distance (in meters) and a confidence score, so you know how close the match is to the coordinates you sent. On a road-name-only answer the distance is to the road, so it does not tell you where any house is.

Is reverse geocoding a separate plan?

No. Forward and reverse geocoding are included together in the same plan, so one subscription covers both directions.

What do I need to get started?

An email address. Sign up, grab your API key, and send your first request. The free tier gives you 3,000 requests a month (up to 100 a day) with no card on file.
