Coordinates to Address

Free reverse geocoder. Paste any latitude / longitude — Decimal Degrees, DMS, or DDM — click the map, or use GPS, and get the full street address with a structured breakdown plus elevation, time zone, and current local time. Batch CSV mode for 25 points at once.

Coordinates → address, with everything else you wanted

The basic reverse-geocoding question is straightforward: given a latitude and longitude, what is the address? Most online tools answer that question with a single line of text and nothing else. Coordinates to Address adds three layers on top.

First, the structured breakdown. Every Nominatim result is parsed into its component fields — house number, street, neighbourhood, city, county, state, postcode, country — each in its own labelled card with a copy button. So when you need the postcode for a billing form or the county for a jurisdictional lookup, you don\u2019t have to parse a comma-separated string.

Second, three coordinate formats out: Decimal Degrees, Degrees-Minutes-Seconds, and Degrees-Decimal-Minutes. GPS receivers and most APIs use DD; surveying and aviation use DMS; marine navigation and handheld GPS use DDM. The same point shows in all three formats side by side — copy whichever your downstream system expects.

Third, enrichment. The result includes elevation (Copernicus 30 m DEM), the IANA time zone, the current local time at that point, and a one-click hand-off to Google Maps, Apple Maps, or OpenStreetMap. The other tools that exist mostly stop at the address string. We figure if you came here for the lat / lng → address conversion, you probably also want to know whether the point is at sea level or 2,000 m up, and what time it is there.

How to convert coordinates to an address

Six steps from coordinates to a full address with rich enrichment.

1. Enter or paste your coordinates. Type latitude into the first box and longitude into the second, or paste a full pair like "40.7128, -74.0060" into either field — the smart parser will split it automatically. Decimal Degrees, Degrees-Minutes-Seconds (40°42′46″N 74°0′21″W), and Degrees-Decimal-Minutes (40°42.768′N 74°0.36′W) are all accepted.
2. Or click anywhere on the map. Click any point on the world map and the latitude / longitude fields fill in instantly. The reverse geocoder runs at the same time. Pinch and drag to zoom into the exact spot before clicking.
3. Or use GPS. Tap "My Location" to grab your current latitude and longitude from your device’s GPS sensor (or Wi-Fi positioning on a desktop). Your browser will ask for permission first; nothing is shared with us.
4. Read the structured address. The result panel shows the canonical Nominatim display name plus a structured breakdown — house number, street, neighbourhood, city, county, state, postcode, and country — each in its own labelled card with a Copy button.
5. Read the enrichment. Three extra cards add value beyond the address: elevation in metres and feet (Copernicus 30 m DEM), the IANA time zone of the point, and the current local time at that location.
6. Open in Google Maps, Apple Maps, or OpenStreetMap. One-click handoff to any of the three major map providers. The hero panel also exposes Copy buttons for the full address and the decimal coordinates so you can paste directly into a CRM, spreadsheet, ticket, or document.

Coordinate formats this tool understands

Three formats are accepted as input — paste any of them into either the latitude or the longitude box (the smart paster will split a full pair). All three are also produced as output side-by-side, so you can convert between formats while reverse-geocoding the point.

For a stand-alone format converter that handles UTM, MGRS, Plus Codes, and OS Grid in addition to the three common formats above, see our GPS Coordinate Converter.

What people use Coordinates to Address for

Seven recurring patterns we see in the analytics — each one is a different industry asking the same lat/lng-to-address question for slightly different reasons.

How reverse geocoding actually works

A reverse geocoder is a database lookup with three stages, optimised for low latency.

Stage 1 — Find the closest building, road, or feature

OpenStreetMap stores hundreds of millions of features (buildings, roads, parks, lakes, administrative boundaries) as polygons, polylines, or points, indexed by an R-tree spatial index. Given an input (lat, lng), the index returns the K nearest features in milliseconds. For a point inside a building polygon, the matching feature is that building. For a point on a road, the matching feature is the nearest road segment plus an interpolated house number. For an open-field point, the match is the nearest named feature in range.

Stage 2 — Walk the administrative hierarchy

Once a feature is matched, the reverse geocoder walks up the administrative hierarchy — building → street → suburb → city → county → state → country — collecting the names, codes, and postcodes it finds along the way. Each administrative level is its own polygon dataset (eg. US Census TIGER/Line for US counties; Eurostat NUTS for European regions; Natural Earth for countries). The result is the structured address you see on the result panel.

Stage 3 — Format the display name

The display name (the long comma-separated string you see at the bottom of the result) is constructed from the structured fields using country-specific rules — Japan starts with the prefecture, France starts with the street number, Brazil includes the bairro before the city, etc. Coordinates to Address returns both the display name and the structured fields, so you can use whichever fits your downstream system.

Nominatim, the engine behind this tool, is the open-source reverse geocoder operated by the OpenStreetMap Foundation. Its source code, data, and documentation are all public — nominatim.org. The tool calls Nominatim\u2019s public endpoint directly from your browser, respecting the Foundation\u2019s 1-request-per-second usage policy.

Forward vs reverse geocoding — which one do I need?

The two operations are inverses; pick the one that matches your input.

Round-trip the two as a quality check: forward-geocode an address into coordinates, then reverse-geocode those coordinates back. If the result matches, the original address was clean. If it doesn\u2019t match, the address was probably ambiguous, abbreviated, or misspelled — useful for QA on a contact list before a marketing send.

Coordinates to Address vs other tools

Honest comparison against the alternatives. Each tool wins different scenarios — the table is a feature checklist, not a value judgement.

Google\u2019s and Mapbox\u2019s reverse geocoders are the most accurate at street-number granularity in the US and Western Europe — they also have the broadest commercial integration story. The trade-off is that you need a paid account, an API key, and you can\u2019t use them for one-off lookups without setup. Coordinates to Address is for the spectrum of users who need an answer right now without configuring an SDK — and the Nominatim data behind it is competitive at the city, county, and state levels.

Tips for accurate reverse geocoding

Use enough decimal places

Six decimal places of latitude / longitude resolve to ≈ 11 cm — more than enough for building-level accuracy. Three decimal places resolve to ≈ 110 m, which lands you at the right block but not the right building. Always pass the full precision your source has; truncating a coord costs precision permanently.

Trust the structured fields more than the display name

The display name is a country-specific concatenation of the structured fields — it can include or omit different levels depending on locale. The structured fields (city, county, state, country) are stable across countries and easier to integrate. Use the display name for human-facing output, the structured fields for everything else.

Watch for ocean / wilderness coordinates

OpenStreetMap doesn\u2019t have addresses for the open ocean, the Antarctic interior, or very remote desert regions. The tool returns "no nearby address" for those points — but still returns elevation and time zone, which always have global coverage. If you expected an address and got "none", verify your coords are on land in a populated region.

Pair with the forward geocoder for QA

Round-tripping addresses through forward → reverse is a cheap QA check. If your forward geocode of "200 Oxford St" returned (51.515, -0.142) and reversing it returns "Oxford Street, London, England, UK", the result is clean. If reversing returns "St James, North York, ON, Canada", the forward geocode disambiguated to the wrong country.

Use batch mode for anything bigger than ~5 points

Single-mode is for one-off lookups; batch mode handles up to 25 at once with CSV export. For more than 25 (1,000+ point asset databases, fleet logs, etc.), break the list into chunks of 25 and submit each chunk separately. The Nominatim usage policy allows 1 req/sec sustained; the tool already enforces this pacing, so chunked batches are safe.
