With Geocodio, you can upload a spreadsheet of US or Canadian addresses or coordinates and get coordinates, approximate addresses.
With Geocodio, you can also enrich your location data by adding Census information such as FIPS codes, Congressional districts/ridings, timezones, and more.
Geocoding is the process of converting addresses to latitude and longitude coordinates (i.e. GPS coordinates) so that a computer can understand them. Computers do not understand addresses; they only understand coordinate pairs. Reverse geocoding, similarly, is the process of converting latitude/longitude pairs into addresses so humans can read them.
Geocodio's geocoding can:
Convert US and Canadian addresses to latitude/longitude, or
