I have a list of addresses for which I need to get the ZIP+4. I am trying to geocode following https://support.esri.com/en/technical-article/000014901 which specifies to select the USA_PostalEXT locator to get the ZIP+4 in the output. Does anyone know what the USA_PostalEXT locator is, and how I can get it? Can I get ZIP+4 using the ArcGIS World Geocoding Service? I have ArcMap 10.5, ArcGIS Pro 2.5.1, and can use Python. AGOL credits are not an issue.
