CLARKTON prefixes in area code 910

NANPA records 3 assigned NXX blocks to rate center CLARKTON in area code 910, 0.4% 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. 3 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - NC (1), TWC IP ENABLED SERVICES, LLC (1), BRIGHTSPEED OF EASTERN NORTH CAROLINA, LLC (1). The earliest assignment on record here is 2005-02-21 and the most recent 2007-07-23. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
