ACS Geocoding

When data is CASS certified, the latitude and longitude values will be returned. These latitude and longitude values are based on the ZIP+4. As part of version ACS 10.1, longitude and latitude fields are part of the person's address record. When the CASS certification results are applied to the data, these fields are also updated in the address record. The latitude and longitude fields are available in Advanced Export so that a file can be created to use in your choice of 3rd party mapping software.
