A menudo utilizo el Bing Maps Rest APIs. Puede geo-código con las solicitudes como las siguientes:
http://dev.virtualearth.net/REST/v1/Locations/CA/adminDistrict/postalCode/locality/addressLine?includeNeighborhood=includeNeighborhood&key=BingMapsKey
se puede ver que en uso en un codeproject article I wrote on reactive extensions.
Por ejemplo, su dirección:
http://dev.virtualearth.net/REST/v1/Locations/US/1125%20E.%20102nd%20Street,%20Los%20Angeles,%20CA?key=Ai9-KNy6Al-r_ueyLuLXFYB_GlPl-c-_iYtu16byW86qBx9uGbsdJpwvrP4ZUdgD
