DUNN-CMBLD prefixes in area code 910

NANPA records 3 assigned NXX blocks to rate center DUNN-CMBLD 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 PAETEC ITEL, LLC (1), BANDWIDTH.COM CLEC, LLC - NC (1), BRIGHTSPEED OF EASTERN NORTH CAROLINA, LLC (1). The earliest assignment on record here is 2006-10-11 and the most recent 2017-03-08. 3 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.
