GeoStan returns match codes that indicate the portions of the address that matched or did not match to the GeoStan Directory file. If GeoStan could not make a match, the match code begins with "E" and the remaining digits indicate why the address did not match. The digits do not specifically refer to which address elements did not match, but rather why the address did not match.
The following table contains the match code values. You can find a description of the hex digits for the different match codes in the table following the match code table.
