NOWILKESBO prefixes in area code 336

NANPA records 14 assigned NXX blocks to rate center NOWILKESBO in area code 336, 1.8% of the 783 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. 10 holders hold those blocks, the largest being BRIGHTSPEED OF NORTH CAROLINA, LLC (5), NEW CINGULAR WIRELESS PCS, LLC - GA (1), ONVOY, LLC - NC (1). The earliest assignment on record here is 2001-11-08 and the most recent 2026-05-29. 10 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 743 – overlay codes cover the same geography, so a rate center is served by all of them.
