NANPA records 3 assigned NXX blocks to rate center PLUMBRANCH in area code 864, 0.4% 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. 3 holders hold those blocks, the largest being WEST CAROLINA RURAL TEL. COOP., INC. (1), SOUTH CAROLINA TELECOMM GRP HOLDINGS, LLC - SC (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2017-10-11 and the most recent 2023-07-06. 1 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
