Geographic Centroid Matches (G category)
•
For either S or M category result codes, each character of the code tells how precisely the geocode
operation matched each address component.
The following example is a close match candidate:
S5HPNTSCZA
The following example is not a close match candidate:
S5-PNTSC-A
A dash in the result code indicates a conflict. If the postal code in the request conflicts with one
found by the geocode in the data (input was 28031, value found is 28013), the resultant string
contains a dash instead of a Z (For example, S5HPNTSC-A).
Single Close Match (S Category)
Matches in the S category indicate that the record was matched to a single address candidate. The
first character (S) reflects that the geocoding server found a street address that matches the record.
The second position in the code reflects the positional accuracy of the resulting point for the
geocoded record.
•
S1 – single close match, point located at postal code centroid
•
S2 – single close match, point located at ZIP+2 centroid (US centric)
•
S3 – single close match, point located at ZIP+4 centroid (US centric)
•
S4 – point located at the center of a shape point path (shape points define the shape of the street
polyline)
•
S5 – point located at a street address position
•
S6 – point located at centroid of geometry postal code. (For example, large buildings having their
own codes). This represents the highest accuracy available
