CHADBOURN prefixes in area code 910

NANPA records 4 assigned NXX blocks to rate center CHADBOURN in area code 910, 0.5% 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. 4 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - NC (1), ONVOY SPECTRUM, LLC (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NC (1). The earliest assignment on record here is 2004-06-09 and the most recent 2024-02-05. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
