LAUREL BAY prefixes in area code 843

NANPA records 5 assigned NXX blocks to rate center LAUREL BAY in area code 843, 0.6% 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. 4 holders hold those blocks, the largest being BRIGHTSPEED OF SOUTH CAROLINA, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - SC (1), HARGRAY, INC. - SC (1). The earliest assignment on record here is 2002-03-15 and the most recent 2018-04-19. 3 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.
