NANPA records 4 assigned NXX blocks to rate center DUE WEST in area code 864, 0.5% of the 784 blocks assigned in the code.

COOP., INC. (1), SOUTH CAROLINA TELECOMM GRP HOLDINGS, LLC - SC (1). The earliest assignment on record here is 2005-09-01 and the most recent 2005-09-01. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
