the Florida Public Service Commission wanted to spare alarm companies and ISPs the cost of reprogramming and replacing systems that could not handle 10 digit dialing. Available numbers for area code 813 are expected to be exhausted during the third quarter of 2022. As a result, the North American Numbering Plan Administrator proposed an "all services overlay", which was approved by the Florida Public Service Commission on March 31, 2020. The new area code 656 is scheduled for initiation of service in mid-to-late February 2022, once all available central office prefixes of 813 have been assigned. This requires ten-digit dialing within the numbering plan area, with recorded messages passed on to callers dialling the old method.
