DUNN prefixes in area code 910

NANPA records 10 assigned NXX blocks to rate center DUNN in area code 910, 1.3% 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. 7 holders hold those blocks, the largest being BRIGHTSPEED OF EASTERN NORTH CAROLINA, LLC (4), CENTURYLINK COMMUNICATIONS LLC - NC (1), SUNCOM DBA T-MOBILE USA (1). The earliest assignment on record here is 2001-01-19 and the most recent 2016-07-28. 8 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.
