Address to coordinates

Type an address to see its latitude and longitude, ready to copy, with the point on the map. Got a list? Paste it or upload a CSV and look up as many as 100 at once.

How to write an address so it gets found

Use the house number, the street, the city, the state and, if you have it, the ZIP code: “200 E Colfax Ave, Denver, CO 80203”. The usual abbreviations work fine (St, Ave, Blvd, NW), and so do full state names.

Leave out apartment, suite and unit numbers (“Apt 4B”, “Suite 300”, “#12”): they’re not part of the street address and they confuse the search. We strip them from lists automatically, but it’s best to leave them out when you search one at a time too. PO boxes can’t be placed on a map, because they don’t have a street location.

What each accuracy level means

House number: the point is at that street number, taken from OpenStreetMap. Street: the street exists but that number isn’t mapped, or you didn’t include one, so the point sits somewhere along the street. City or town: only the place was found, and the point is its center. ZIP code: the center of that ZIP code area. Named place: a well-known spot such as a museum, a station or a park, with its own point.

In a list, each address also gets a status. Found: it’s a house number or a named place that matches what you typed, including the number and the city or ZIP code. Approximate: something similar turned up, but not everything lines up (another city, another number, only the street or only the town), so check it on the map. Not found: nothing looks like what you typed.

Why an address can land in the wrong place

The most common reason is that the same street name exists in many towns. There are thousands of Main Streets, Oak Avenues and First Streets, and without the city and state the search has to guess. Brand-new developments, rural routes, streets that changed names and typos can cause trouble too. OpenStreetMap has house numbers for most US cities, but not every single one, and where a number is missing you’ll get the street.

To catch mistakes, the tool compares every result with what you typed and keeps the one that matches best, not just the first. Still, check the approximate ones: tap Fix to pick another match, search for the address another way or tap the exact spot on the map.

Your addresses never touch our servers

Mapsfera doesn’t have a server that receives your addresses. Your browser asks a free public service directly: Photon, run by Komoot with OpenStreetMap data. It sends the addresses one at a time with a short pause in between so the service doesn’t get overloaded. That’s why a list tops out at 100 and 100 addresses take a few minutes.

The list is saved only in your browser, so you won’t lose it if you reload the page, and Clear the list deletes it. If you have thousands of US addresses, this isn’t the right tool: the US Census Bureau Geocoder is free and takes batch files of up to 10,000 addresses, and paid geocoding services can handle much more.

Frequently asked questions

How many addresses can I geocode at once?

Up to 100 per list. They’re looked up one at a time, with a short pause in between, because the services behind the tool are free and public. When you’re done, download the results and start a new list with the next batch.

Are my addresses stored anywhere?

Not on a Mapsfera server, because there isn’t one. Each address goes from your browser to Photon, a free public address search, to be looked up. The list stays in your browser so you don’t lose it when you reload, and you can delete it any time with Clear the list.

What should my CSV look like?

One row per address, with columns separated by commas, semicolons or tabs (the tool figures it out). If the address is split across several columns, such as street, city, state and ZIP, select them all and they’ll be joined. From Excel, use Save As and pick “CSV UTF-8”.

What do I do if an address is approximate or not found?

Tap Fix on its row. You can pick one of the other matches, search for it another way (adding the city, state or ZIP code helps) or tap the exact spot on the map. The row switches to Fixed and your download includes the corrected point.

What format are the coordinates in?

Decimal degrees on the WGS84 datum, the same as Google Maps and GPS devices: “39.739210, -104.984850”. With six decimal places they’re precise to about 4 inches. If you need UTM or degrees, minutes and seconds, use the coordinate converter.

Does it work for addresses outside the US?

Yes. Addresses anywhere in the world come from Photon, with OpenStreetMap data. Many countries have nearly every house number mapped; where they’re missing, you’ll get the street and an approximate result. For lots of addresses in Spain, the Spanish version of this tool also checks CartoCiudad, the official Spanish address database.
