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.

  • Have you tried the ArcGIS World Geocoding Service?

I couldn't find an answer to what or where the USA_PostalExt locator is, but I was able to get the desired results following the workflow in the link and using the ArcGIS World Geocoding Service. The PostalExt attribute field is populated after reverse geocoding.enter image description here
