GEORGETOWN prefixes in area code 843

NANPA records 16 assigned NXX blocks to rate center GEORGETOWN in area code 843, 2.0% 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. 8 holders hold those blocks, the largest being FRONTIER COMMUNICATIONS OF THE CAROLINAS INC. - SC (5), SUNCOM DBA T-MOBILE USA (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SC (2). The earliest assignment on record here is 2002-01-30 and the most recent 2018-09-28. 10 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 codes 203, 217, 229, 302 – overlay codes cover the same geography, so a rate center is served by all of them.
