Geocode an Address

Convert an address to geographic coordinates

Geocodio is a address-to-lat-long converter that supports US, Canadian, and Mexican addresses. Enter an address in the tool below to get coordinates and a standardized address. To convert addresses to lat long in bulk, upload a spreadsheet or use the Geocodio API. The first 2,500 lookups per day are free.

Convert coordinates to an address

Reverse geocoding does the opposite: it takes latitude and longitude coordinates and returns the nearest street address. Geocodio supports reverse geocoding for the US, Canada, and Mexico through the tool above, the API, and spreadsheet uploads.

What Geocodio returns when you geocode an address

Every geocoded result includes:

• Latitude and longitude coordinates at rooftop precision when available, with accuracy types (rooftop, parcel centroid, range interpolation, street center) so you always know how precise the match is

• A standardized, corrected address with each component separated: street number, directional, street name, suffix, city, county, state/province, postal code, and country

• An accuracy score from 0 to 1 that tells you how closely the result matches your input

• A stable address key that serves as a permanent identifier for that address, useful for deduplication across lists and over time

Find the GeoID, FIPS code, or census tract for an address

Looking for a geographic identifier for an address? Geocodio returns FIPS codes, census tracts, block groups, blocks, and other geographic identifiers (GeoIDs) for any US address. These are the codes that connect addresses to government datasets like the American Community Survey, FFIEC income data, and more.

You can look up a GeoID for a single address using the tool above (select "Census" under data appends) or process an entire spreadsheet at once.

Address standardization and spelling correction

Addresses in the real world are messy. People leave out ZIP codes, misspell street names, forget directionals, and abbreviate things differently every time.

Geocodio parses and standardizes every address it processes. That means correcting minor typos, filling in missing components where possible, expanding abbreviations, and returning a clean, consistently formatted version alongside coordinates.

This is especially useful when working with user-submitted data, CRM exports, purchased lists, or any dataset where addresses were entered by hand.

Enrich addresses with additional data

Geocoding is just the starting point. Geocodio can add over 40 types of data to any address or coordinate pair with just one click.

• Census geographies: FIPS codes, census tracts, block groups, blocks, county subdivisions, metropolitan statistical areas, and census-designated places

• Census ACS demographics: Household income, poverty rates, education levels, age and gender distributions, housing data, and more from the American Community Survey

• FFIEC income data: Every census tract categorized as low, moderate, middle, or upper income for fair lending compliance

• Political districts: Congressional districts, state legislative districts, Canadian federal and provincial ridings, and legislator contact information

• USPS data: ZIP+4 codes, carrier route IDs, Residential Delivery Indicator (RDI), and exact match validation against the USPS database

• School districts: Unified, elementary, and secondary school district boundaries

• Timezones: Timezone name and UTC offset for every geocoded location

All data appends are available through both the API and the spreadsheet upload tool.

How to convert addresses to lat long

Geocodio offers several ways to convert addresses to coordinates, depending on how many addresses you have and how you want to work.

Convert a single address

Use the tool at the top of this page. No account required. For repeated lookups, the Geocodio API handles real-time conversion with a simple GET request.

Convert a spreadsheet of addresses in bulk

Upload a CSV, TSV, or Excel file and Geocodio will return coordinates, standardized addresses, and any data appends you select. Files up to 1GB. Try it now with 2,500 free lookups per day.

Batch address to lat long via API

The Geocodio REST API supports batch processing of up to 10,000 addresses per request, plus large-scale list processing for millions of addresses. Client libraries are available for Python, Ruby, Node.js, PHP, R, Clojure, and more.

Convert addresses from the command line

The Geocodio CLI handles geocoding, reverse geocoding, distance calculations, and batch processing directly from the terminal.

Accuracy and data sources

Geocodio sources data from over 2,000 public data sources across the US, Canada, and Mexico. Data is updated nearly every day.

Every result includes an accuracy type and accuracy score so you can filter results by precision. Geocodio's average accuracy score is 0.981 out of 1.0, with rooftop-level precision for the majority of US addresses.

When Geocodio cannot match an address at the street level, it returns the best available result (such as a city or ZIP code centroid) and clearly labels the accuracy type so you can decide how to handle it.
