I have 1.4 million addresses that I need to batch geocode. I can't find a free service to do so. Does anyone know of something out there that I can use? Oh, the service needs to be were I can upload a file in a .txt file formate, not a copy and paste. Copy and paste services crash the 661 mb size file.

You could try Nominatim from OpenStreetMap:

Nominatim (from the Latin, 'by name') is a tool to search OSM data by name and address and to generate synthetic addresses of OSM points (reverse geocoding). It can be found at http://nominatim.openstreetmap.org

You may need to write the wrapper functionality to allow uploading of a text file.


You could try MMQGIS plugin in QGIS. It uses Google API for geo-coding and reverse geo-coding.


Go to MMQGIS tab> Transfer > Geocode CSV from Google.

It takes CSV file as input but output geocoded file and not-found-addresses file in case of no address found on google map. Make sure your CSV is in the right format for this plugin.


SmartyStreets has a Bulk Address Validation Tool for Lists service that is designed to do exactly what you're looking for: You upload a list (.csv, .txt, or .xls) and a few minutes later you download the output files, which give 45 data points, including geocode data, for each address.

Our pricing is very competitive, with no minimum purchase price, and if you're a startup or a nonprofit, then you can probably get our service for free.
