SUMMERTON prefixes in area code 803

NANPA records 4 assigned NXX blocks to rate center SUMMERTON in area code 803, 0.5% of the 784 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. 4 holders hold those blocks, the largest being FRONTIER COMMUNICATIONS OF THE CAROLINAS INC. - SC (1), FTC DIVERSIFIED SERVICES, INC. (1), LEVEL 3 COMMUNICATIONS, LLC - SC (1). The earliest assignment on record here is 2008-05-12 and the most recent 2018-09-26. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
