After you make a map, you can get the geocoding accuracy results by copying the data from the data window and look at the column "bg_accuracy".  

• location_type stores additional data about the specified location.

The following values are currently supported:

• "ROOFTOP" indicates that the returned result is a precise geocode for which we have location information accurate down to street address precision.
• "RANGE_INTERPOLATED" indicates that the returned result reflects an approximation (usually on a road) interpolated between two precise points (such as intersections). Interpolated results are generally returned when rooftop geocodes are unavailable for a street address.
• "GEOMETRIC_CENTER" indicates that the returned result is the geometric center of a result such as a polyline (for example, a street) or polygon (region).
• "APPROXIMATE" indicates that the returned result is approximate.
