If you have more than a couple thousand records you want to geocode all at once we found a great service from USC’s GIS department that allows you to geocode records in an Access database. It’s not terribly fast but we were able to geocode nearly 200,000 records in a couple of days. Just make sure your computer isn’t set to go to sleep an hour after you step away from the computer…. :/
