LOC_CODE Location codes indicate the accuracy of the assigned geocode. For descriptions of location codes, see Address Location Codes in the appendix.
MATCH_CODE Match codes indicate the portions of the address that matched or did not match to the reference file. For descriptions of match codes, see Match Codes in the appendix.
POSTAL_FALLBACK USA fallback candidates returns the correct MatchCode and LocationCode indicating a postal fallback, rather than codes indicating a postal level geocode.
MM_RESULT_CODE The MapMarker result code for this candidate. See result codes in Global Result Codes in the appendix.
