GA - missing US postal code areas (not all have areas)
I was troubleshooting a complaint of missing postal code area geometries from GeoAnalytics. I didn't previously realize this, but not all postal codes (in the USA) have areas. Some examples: 77001, 77052, 77202, 77203:
These postal codes are in the GeoAnalytics location database for point geometry (they have center point coordinates)
But they are not in the GeoAnalytics location database for area geometry.
