Postal Centroid Matches (Z category)
Matches in the Z category indicate that a postal centroid geocode is returned.
Each of the Z codes is defined below. The second position in the code reflects the positional accuracy of the resulting point for the geocoded record.
| Code | Description |
|---|---|
| Z1 | ZIP Code (5-digit) centroid match. |
| Z2 | ZIP + 2 centroid match. |
| Z3 | ZIP + 4 centroid match (highest accuracy available for Z matches). |
| Z0 | ZIP Code match, no coordinates available (very rare). |
| Z6 | ZIP Code centroid match for a point ZIP. A Z6 code is returned when the candidate is matched to a point ZIP centroid. Point ZIPs are 5-digit ZIP Codes that are points on a map rather than a polygon. Point ZIPs include unique ZIPs (single site, building, or organization). Instead of returning a Z1 result code, the Z6 code indicates that these special ZIPs are actual point locations, not an area. |
