I am working on a project where users fill out an online form with address information and a Google Map centered at that address is displayed. It works fine for traditional addresses (e.g. 123 Main Street, New York, NY) but I have no idea where to start with geocoding rural information.
How can I get map information for rural routes, preferably via Google Maps? In my form, a user enters a rural route descriptor, a rural route number, a box number, a city, a state, and a zip code.
