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 a description of the

not specifically refer to which address elements did not match, but rather why the
address did not match.
