Geocoding Accuracy Levels

Geocoding is the process by which the street address is converted into geographic coordinates (Latitude and Longitude). The accuracy code provides you with the level of precision which it was able to assign the coordinates based on the address provided. Sites not geocoded are excluded from the processed sites and listed in the error log accessible via My Projects.

Below is the list of all the codes and their meaning:
