Data Sources

We are not reselling another geocoder's results. We have developed and continually refined our own proprietary geocoding engine over the past eight years. When you submit an address or coordinate pair for geocoding, our geocoding engine interprets your query and delivers a result fueled by underlying source data.

We return the source information with all of our results.

Because we have built our own geocoding engine and have combined many different data sets, results from Geocodio may be different from results from other providers. You can see more on accuracy here.

Geocodio's data sources include:

• The US Census Bureau
• Local city, county, and state datasets from OpenAddresses
• OpenStreetMap
• GeoNames
• CanVecPlus by Natural Resources Canada
• StatCan
• Legislator information from the UnitedStates project on GitHub
