I just wanted to start off by saying that after an exhaustive search for the subject matter online, I couldn't find anything that didn't confirm my suspicions. I just wanted to ask the community, including ESRI employees that participate, if there is a geocoding service, paid or free, that ESRI offers that is confined to North America and accepts single-line input. Just didn't want to leave any stones unturned. Thank you for your help!
If you have an ArcGIS Online account you can do your geocoding it just costs you credits. Another option would be Google Fusion Tables or if you are familiar with QGIS there is a geocoding plugin. The latter two are free but I believe there is a limit to the number of address you can geocode in 24 hours with the fusion tables.
