Remarks

Address candidates are defined by a number of candidate fields. Each candidate field describes some part of the address information for the match candidate. An address locator uses these candidate fields to determine how well a candidate matches an address. The candidate fields that are generated by the address locator styles provided with ArcGIS are described below:

From - The beginning of the address range.
FromLeft - The beginning of the address range on the left side of the street.
FromRight - The beginning of the address range on the right side of the street.
HouseNum - The street number of the address.
KeyField - The single field describing the address.
LeftCity - The city on the left side of the street.

PreType - The street prefix type.
RightCity - The city on the right side of the street.
RightZip - The ZIP code on the right side of the street.
RightZone - The zone on the right side of the street.
Score - A score between 0 and 100 that indicates how well a candidate matches an address. A score of 100 represents an exact match.
Shape - The geometry of the match candidate.
Side - For geocoding services that can match addresses to a particular side of a street, the side of the street on which the address matches the candidate. A value of "L" indicates the left side of the street, and a value of "R" indicates the left side of the street.
State - The state.
StreetName - The street name.
StreetType - The street type.
SufDir - The street suffix direction.
