MTPLEASANT prefixes in area code 843

NANPA records 19 assigned NXX blocks to rate center MTPLEASANT in area code 843, 2.4% 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 BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (7), PAETEC ITEL, LLC (5), LEVEL 3 COMMUNICATIONS, LLC - SC (2). The earliest assignment on record here is 2001-05-18 and the most recent 2019-06-24. 14 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 319, 430, 435, 662 – overlay codes cover the same geography, so a rate center is served by all of them.
