Further details

The US (of America) uses ZIP and ZIP+4 codes when referring to a location. It is common practice to use ZIP, but ZIP+4 is mostly used for accelerating processing/delivery of items. You can probably offer a suggestion with the zip code converted to ZIP instead of ZIP+4 such as "901 South Stewart Street, CARSON CITY, NEVADA 89701,US"

This used to work in the PHP frontend. I dropped it in Python because it seemed such a niche application. Maybe we should find a proper solution for #1011 instead of hacking ZIP+4 codes back in.

I think it will be fine to detect zip+4 and query for both types, returning both as a single response (or a "did you mean?" response).
