Match Codes
The geocoder returns match codes indicating the address portions that matched or did not match to the database.
If the geocoder cannot make a match, the match code begins with "E" and the remaining digits indicate why the address did not match. For the descriptions of the "E" match codes, see Match Codes for No Match - Definitions for "Ennn" return codes. The digits do not specifically refer to which address elements did not match, but rather why the address did not match.
