| Geocodio [1] is another really good service to look into too: * Good free and premium paid service * They've gone a bit above and beyond to provide examples/demos in all languages in their docs. Super easy for users * Can process bulk/batch request super fast in parallel on your behalf * Have a super cool front-end CSV upload tool built in React so non-programmers can geocode data in seconds * Forward/reverse geocoding * Also give Census data, congressional districts, state legislative districts, and even school districts Full disclosure: I know the husband and wife founder. Very nice people [1]: https://geocod.io |
If geocoding needs are enterprise-grade / you are OK with spending a bit, you should look at Mapzen, OpenCage, and now, Geocodio.
