Address to Coordinates
Turn a street address or place name into latitude and longitude, see it on a map, and copy the coordinates in the format you need.
About Address to Coordinates
Geocoding turns a human address into a pair of numbers a map can use. Type an address, a place name, or a landmark, and this tool returns its latitude and longitude along with the full matched address so you can confirm it found the right thing.
Results come from Nominatim, the geocoding service built on OpenStreetMap. Because it is open data, coverage is excellent in well-mapped urban areas and thinner in places where OpenStreetMap contributors have been less active — which is worth knowing before relying on it for a rural address.
Coordinates are shown in decimal degrees and in degrees-minutes-seconds, since surveying and aviation contexts still expect DMS. Each result is one click to copy, and the map preview lets you sanity-check the match before you use it.
How to use it
- 1Type an address, place name or landmark into the search box.
- 2Press Search and review the matched results.
- 3Check the map preview to confirm it found the right location.
- 4Copy the coordinates in decimal degrees or DMS.
Common uses
- Getting coordinates for a site visit or survey point
- Adding latitude and longitude columns to an address list
- Finding coordinates to centre a map on a specific place
- Checking that an address resolves to where you expect
Frequently asked questions
Do I need an API key?
No. The tool queries OpenStreetMap's public Nominatim service, which is free and needs no registration. It does enforce a fair-use rate limit of roughly one request per second, so this is built for looking up addresses one at a time rather than processing a spreadsheet.
Why can it not find my address?
Usually because that exact address is not in OpenStreetMap, which is common for new developments and rural properties. Try a less specific query — the street and city rather than a house number — or search a nearby landmark and adjust from there.
Is this request private?
The address you type is sent to OpenStreetMap's servers, because geocoding requires a database no browser can hold. This is the one tool in this set that necessarily makes a network request. Nothing else about you is transmitted, and no results are stored.
How accurate are the coordinates?
For a matched building, typically within a few metres. For a street without a house number match, the result is a point on the street rather than a specific property. The returned match type tells you which you got — always check it before treating a result as precise.
