Location codes indicate the locational accuracy of the assigned geocode. Note that an accurately placed candidate is not necessarily an ideal candidate. Examine the match codes and/or result codes in addition to location codes to best evaluate the overall quality of the candidate.
A Location Code of "E" indicates a location code is not available. This usually occurs when you have requested ZIP Code centroids of a high quality, and one is not available for that match. It can occur infrequently when Enterprise Geocoding does not have a 5-digit centroid location. Enterprise Geocoding can also return an "E" location code when it cannot standardize an input address and there is no input ZIP Code. In this case, do not assume the ZIP Code returned with the non-standardized address is the correct ZIP Code because Enterprise Geocoding did not standardize the address; therefore, Enterprise Geocoding does not return geocoding or Census Block information.
