CLAYTON prefixes in area code 919

NANPA records 10 assigned NXX blocks to rate center CLAYTON in area code 919, 1.3% of the 781 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. 5 holders hold those blocks, the largest being METROPCS, INC. (3), BRIGHTSPEED OF EASTERN NORTH CAROLINA, LLC (3), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2010-07-12 and the most recent 2012-03-16. 7 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 codes 208, 217, 315, 317 – overlay codes cover the same geography, so a rate center is served by all of them.
