EDISTO IS prefixes in area code 843

NANPA records 4 assigned NXX blocks to rate center EDISTO IS in area code 843, 0.5% of the 783 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 3 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (2), PAETEC ITEL, LLC (1), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (1). The earliest assignment on record here is 2003-04-18 and the most recent 2003-04-28. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 854 – overlay codes cover the same geography, so a rate center is served by all of them.
