CAROLINBCH prefixes in area code 910

NANPA records 6 assigned NXX blocks to rate center CAROLINBCH in area code 910, 0.8% of the 785 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. 6 holders hold those blocks, the largest being CENTURYLINK COMMUNICATIONS LLC - NC (1), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (1), PEERLESS NETWORK OF NORTH CAROLINA, LLC - NC (1). The earliest assignment on record here is 2007-10-23 and the most recent 2016-01-05. 5 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 472 – overlay codes cover the same geography, so a rate center is served by all of them.
