Geocoding is the process of transforming a table of street addresses into longitude and latitude coordinates. While finding a coordinate for a single point may be simpler to geocode manually, if you need tens or hundreds of addresses transformed into coordinates, you will want to use a batch geocoder.

See the Geocoding in ArcGIS guideline and geocoding tutorial for more information on how the geocoding process works. A brief overview of some available geocoding tools is provided below.

If you want help with geocoding, or if your geocoding needs include a large number of addresses, do not hesitate to contact us at libraryrdds@pobox.upenn.edu. 

If you expect to regularly need to geocode tens of thousands of addresses, additional licenses may need to be acquired.
