CAROLEEN prefixes in area code 828

NANPA records 4 assigned NXX blocks to rate center CAROLEEN in area code 828, 0.6% of the 724 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 PEERLESS NETWORK OF NORTH CAROLINA, LLC - NC (1), AT&T ENTERPRISES, LLC (1), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (1). The earliest assignment on record here is 2011-05-16 and the most recent 2023-08-21. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
