For - more than 10 years - we have been developing an "Outstanding" address validation and geocoding program: >>> IC-AddressValidation.
Based on Navteq map data from Microsoft MapPoint, it is still used by many of our customers today.

Unfortunately, this excellent program has not been sold by Microsoft since 2014.

As a Microsoft ISV partner we have sold more than - 1,000  Microsoft MapPoint - and several hundreds of our tools - including
the - IC-AddressValidation - program - worldwide. 

The further development now presented  IC-AddressValidation (2018)  combines our experience with the new possibilities
of OSM (OpenStreetmaps), BING maps and Google maps.
