Address to Latitude & Longitude — Free Online Geocoder
Geocoding is the technique of converting a descriptive postal address or location name into geographic coordinates — specifically latitude and longitude. These coordinates can then be used to plot the address on a map, conduct spatial analysis, or power any location-based application such as delivery routing, navigation or logistics platforms.
This tool is a simple, intuitive geocoder. Enter any address in the search bar and click Get GPS Coordinates. The tool queries the OpenStreetMap Nominatim database — the world's largest open geographic dataset — and returns the best matching location as a red pin on the map, with decimal degree and DMS coordinates shown in the result strip.
It accepts full street addresses, city or town names, postcodes and ZIP codes, country names, famous landmarks, and even raw lat,lng coordinate pairs. Results can be copied to clipboard or shared via WhatsApp.

A Brief History of Geocoding
Geocoding is not a new concept — its history is intertwined with cartography, computing and government infrastructure over more than a century.
Pre-Digital Era (19th Century – 1960s): In analog form, an address was looked up in a street index at the back of a paper map. A grid reference (e.g. "B-5") was found in the index, then located on the map. The US Census Bureau was a pioneer: for the 1960 and 1970 censuses, the challenge of tabulating data by geographic location drove the creation of the first digital geographic databases.
1964 — First Digital Geocoder: The Harvard Laboratory for Computer Graphics developed the first automated geocoding system to support the US Census Bureau — a seminal moment in the history of GIS.
1970s–1990s — TIGER Files: The US Census Bureau developed the TIGER (Topologically Integrated Geographic Encoding and Referencing) system, which became the backbone of address-based geocoding in North America.
1990s–2000s — Commercial Geocoders: As GPS receivers became affordable for civilians, commercial geocoding APIs emerged from companies like MapQuest, ESRI and later Google. Web mapping changed how people navigated.
2004–Present — Open Geocoding: OpenStreetMap (2004) created the world's first open, community-maintained geographic dataset. Nominatim, its geocoding engine, now powers thousands of apps and tools — including this one — with no licence fees.

How to Use — Step by Step
1
Tool Opens on World Map
The geocoder loads with a world map and an address search bar at the top. A prompt in the centre explains what the tool does. You can type any address, city, postcode, landmark name, or raw lat,lng coordinates into the search field.
2
Type Your Address
Type any address into the search bar — a full street address, a city name, a postcode/ZIP code, a country, a well-known landmark, or even a set of lat,lng coordinates. The tool accepts partial addresses and handles international addresses in all character sets.
3
Click "Get GPS Coordinates"
Press the red "Get GPS Coordinates" button or hit Enter. The geocoder queries the OpenStreetMap Nominatim database and returns the best matching location. A loading spinner appears while the search is in progress.
4
Red Pin Drops on the Map
A red map pin drops at the geocoded location. The map automatically zooms to that point at street level. The result strip below the search bar shows the full matched address, decimal latitude and longitude, and the DMS (degrees, minutes, seconds) equivalent.
5
Click Pin for Coordinate Details
Click the red pin marker to open the coordinate popup. It shows the full address, latitude and longitude in decimal format, DMS format for both lat and lng, and a Share via WhatsApp button to send the coordinates to a contact.
6
Multiple Results Dropdown
If the address matches several places (e.g. "Springfield" exists in multiple US states), a dropdown appears listing all matches with their coordinates. Click any result to zoom to it and update the coordinate display.
7
Copy Coordinates to Clipboard
Use the "Copy Decimal" button to copy latitude and longitude as decimal degrees (e.g. 51.500000, -0.126000) or "Copy DMS" to copy degrees, minutes and seconds format. Both copy to clipboard instantly — paste directly into any app.
8
Share via WhatsApp
Press "WhatsApp" in the result strip to share the address and coordinates as a formatted message. The message includes the full address, decimal coordinates, DMS format and a link to the tool. On mobile this opens WhatsApp directly; on desktop it opens WhatsApp Web.
9
Switch to Satellite View
Click the "Satellite" button in the toolbar to switch to aerial imagery. The red pin remains visible. Satellite view lets you verify the geocoded point visually — useful for confirming a rooftop address, industrial estate or rural location.
10
Geocode by Lat,Lng Directly
Type a pair of coordinates directly into the search box (e.g. "48.8566, 2.3522") and press Enter. The tool recognises decimal coordinate input and places the pin at those exact coordinates, then displays the formatted address information in the result strip.

Frequently Asked Questions
- What is geocoding and how does this tool work?
- Geocoding is the process of converting a human-readable address or place name into geographic coordinates (latitude and longitude). This tool sends your query to the OpenStreetMap Nominatim geocoding API, which searches its global database of addresses, place names, postcodes, and landmarks. The best matching result is displayed as a red pin on the map with decimal and DMS coordinates.
- What types of addresses can I search for?
- The geocoder accepts a wide variety of inputs: full street addresses (e.g. "10 Downing Street, London"), city names, postcodes or ZIP codes, country names, famous landmarks (e.g. "Eiffel Tower"), airport codes, district names, and coordinate pairs in decimal format (e.g. "51.5074, -0.1278"). International addresses in non-Latin scripts (Arabic, Chinese, Japanese, Cyrillic etc.) are also supported.
- What is the difference between decimal degrees and DMS format?
- Decimal degrees (DD) express coordinates as a single number with a decimal fraction — e.g. 51.507400, -0.127800. Degrees, minutes and seconds (DMS) breaks each coordinate into three parts — e.g. 51° 30' 26.64" N, 0° 7' 40.08" W. Both represent the same point. Decimal degrees are used in most software, APIs and CSV files. DMS is common in traditional cartography, surveying and some GPS devices.
- How accurate are the coordinates returned?
- Accuracy depends on the quality of the OpenStreetMap data for the searched location. For addresses in well-mapped areas (Western Europe, North America, Japan, Australia), coordinates are typically accurate to within a few metres. For rural areas or less-documented regions, the result may be at the centre of a street, district or city rather than a specific building. Always verify on the satellite view if precise placement is needed.
- Can I geocode a postcode or ZIP code?
- Yes. Enter any UK postcode (e.g. "SW1A 2AA"), US ZIP code (e.g. "10001"), Indian PIN code, German PLZ, French code postal, or any other national postcode format. The result will be the centroid of that postal area. For single-address precision, include the full street address and postcode together.
- What do I do if multiple results appear?
- When an address is ambiguous (e.g. "Springfield" matches dozens of cities in the USA), a dropdown list appears showing all matched results with their country and coordinates. Click the correct entry to zoom to that location. Adding more detail to your query — such as the state or country — will narrow the results to a single match.
- Can I enter coordinates to find an address (reverse geocoding)?
- If you enter a lat,lng pair (e.g. "48.8566, 2.3522"), this tool places the pin at those exact coordinates and displays the nearest known address from OpenStreetMap's data. For dedicated reverse geocoding (clicking on a map to get the address), use our Reverse Geocoding tool which is specifically designed for that workflow.
- How do I use these coordinates in Google Maps?
- Copy the decimal coordinates using the "Copy Decimal" button, then paste them directly into the Google Maps search bar. Google Maps accepts decimal degree coordinates in the format "lat, lng" — for example "51.500000, -0.126000". Press Enter to zoom to that point. You can also paste them into Google Earth, Bing Maps, ArcGIS, QGIS, or any GIS application.
- What does it cost to convert an address into coordinates here?
- Nothing — no account, API key, or credit card is involved. Lookups run through OpenStreetMap Nominatim, an open geocoding service built on the world's largest open geographic database, and normal one-address-at-a-time usage has no daily cap.
- What is the history of geocoding?
- Geocoding in analog form dates back centuries — street indexes in paper maps referenced grid cells like "B-5". The first digital geocoding system was developed in 1964 at the Harvard Laboratory for Computer Graphics to support the US Census Bureau. The 1990s saw commercial geocoders emerge as GPS receivers became affordable. Today, open geocoders like Nominatim and commercial APIs like Google's Geocoding API handle billions of requests per day for navigation, logistics, delivery and spatial analysis.
