List of geocoding systems
This is a list of geocoding systems, in the sense of schemes that assign systematic labels to geographic entities.
This is not a list of software systems that can perform geocoding in the sense of turning a geographic name into a latitude and longitude.
Some of these code systems are free for use, others have different licences.
