Returning ZIP Centroids with Master Location Data
ZIP Centroid returns are optionally available when matching to Master Location Data (MLD) in the Geocode US Address stage. For addresses that don't have a high-quality location, this provides access to the pbKeyTM unique identifier, which can be used to unlock additional information about an address using GeoEnrichment data, as well as to realize operational processing efficiencies. This allows us to ensure maximum address coverage and integrity in geocoding. The inclusion of these addresses enables us to provide a higher match rate, lower false-positive match rate, and access to the pbKeyTM unique identifier for all known addresses in the US.
