How to Convert Address to Latitude and Longitude
Converting an address to latitude and longitude — called forward geocoding — is the process of taking a human-readable location like "1600 Pennsylvania Ave NW, Washington, DC" and returning the two numbers that pinpoint it on Earth: 38.8977, -77.0365. Every mapping application, GPS device, and location-based service in the world runs on these coordinates. This guide covers three methods for conver...

Lat Long Lookup: How to Find Latitude and Longitude for Any Address
A lat long lookup is the process of finding the latitude and longitude coordinates for a specific location. You start with something human-readable — a street address, a city name, a ZIP code — and get back the two numbers that pinpoint that place on Earth. The reverse works too: start with coordinates and find the address. This is one of the most common tasks in mapping, logistics, data analysi...

Geocoding Software for Insurance: Risk Assessment, Claims & Fraud Detection
An insurance underwriter in Florida reviews 200 new homeowner applications every week. Each one includes an address. The underwriter needs to know: Is this home in a flood zone? How far is it from the nearest fire station? Is the neighborhood prone to vehicle theft? Every answer depends on one thing — converting that address into geographic coordinates. Without geocoding, this analysis is manual....

How to Convert Address to Lat Long in Excel (5 Methods Compared)
You have a spreadsheet full of addresses and you need latitude and longitude for each one. Maybe it is 50 customer locations, 500 store addresses, or 5,000 delivery stops. Excel does not have a built-in geocoding function, so you need an external method. This guide compares every practical way to convert addresses to lat/long coordinates in Excel — from free formulas to bulk tools that handle 50,0...

How to Reverse Geocode Coordinates to Addresses in Bulk
A logistics company in São Paulo collected 50,000 GPS pings every day from its delivery fleet. Latitude, longitude, timestamp, vehicle ID. Clean data, precise to 3 meters. But the operations team could not use any of it — because nobody on the team reads coordinates. They needed addresses. "Where did truck 47 stop for 12 minutes?" is a useful question. "What happened at -23.5614, -46.6558?" is not...

Reverse Geocoding API: Should You Build or Buy?
In March 2024, a fleet management startup in Lagos called an emergency meeting. Their delivery verification system — built on Google’s reverse geocoding API — was returning addresses for only 47% of their GPS pings. The other 53% came back as "unknown" or pointed to locations kilometers away. Google’s coverage of Nigerian street addresses was simply too thin. They had two choices: build their own...

Reverse Geocoding: How to Convert Latitude and Longitude to Address
On January 15, 2009, US Airways Flight 1549 lost both engines after striking a flock of geese over the Bronx. Captain Sullenberger glided the Airbus A320 to a dead-stick landing on the Hudson River. Within 90 seconds, the first rescue boats were en route. Not because someone radioed a street address — there is no street address in the middle of the Hudson. Because the aircraft’s transponder broadc...
