The Location Codes indicate the methodology used to compute the geocode and may also provide some information about the quality of the geocode.
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 Spectrum Enterprise Tax does not have a 5-digit centroid location. An "E" location code type may also be returned when the input address cannot be standardized and there is no input ZIP Code. In this case, do not assume the ZIP Code returned with the nonstandardized address is the correct ZIP Code because Spectrum Enterprise Tax did not standardize the address; therefore, Spectrum Enterprise Tax does not return geocoding or Census Block information.
