As of 2008, the area code was active and assignable [cite web|url=http://www.nanpa.com/nas/public/npa_query_step2.do?method=displayNpa&npaReportModel.nasNpaId=470|title=NPA Query for Area Code 470|publisher=North American Numbering Plan Administration|accessdate=2008-08-28] but not yet utilized, [cite web|url=http://www.nanpa.com/nas/public/plannedNpasNotInServiceReport.do?method=displayPlannedNpasNotInServiceReport|title=Planned NPAs Not Yet in Service|publisher=North American Numbering Plan Administration|accessdate=2008-08-28] and the routing test number 470-666-7777 was removed from service.
Whether this lack of utilization is due to lack of need or possible confusion with 404 and 770 is unknown. Because of Atlanta's expansive local calling area with three active area codes,
Atlantansoften use a shorthand for area codes based on the first digit ("4" for 404, "6" for 678, and "7" for 770), which would make 470 (starting with "4" like 404, but otherwise similar to 770) difficult to incorporate.
