you have some addresses that are badly formated for the google geo coder to lookup.
a few of the addresses use ranges for the street address, for example:
15 - 21 Arctic Parkway, Ewing Township, New Jersey, 08638
In most cases the google geocoder will fail on looking up addresses that use a range like this.
soem Addresses use an intersection:
Route 70 & Cooper Avenue, Marlton, New Jersey, 08053
this can also cause the geocoder to fail
others include additional info in parenthesis:
421 W. Butler Pike (Route 202), Chalfont, Pennsylvania, 18914
the geocode does not recognize this.
It's not that there is a limit to the number of addresses that can be returned, but the addresses fed to the geocoder need to be properly formatted in order for the location to be mapped.
