HERTFORD prefixes in area code 252

NANPA records 3 assigned NXX blocks to rate center HERTFORD in area code 252, 0.4% of the 695 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. 2 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - NC (2), BRIGHTSPEED OF EASTERN NORTH CAROLINA, LLC (1). The earliest assignment on record here is 2006-05-31 and the most recent 2021-11-04. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
