KNOTTS IS prefixes in area code 252

NANPA records 4 assigned NXX blocks to rate center KNOTTS IS in area code 252, 0.6% 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. 4 holders hold those blocks, the largest being VERIZON SOUTH, INC. - NC (1), TERRA NOVA TELECOM INC. (1), NUSO, LLC (1). The earliest assignment on record here is 2019-04-25 and the most recent 2023-08-29. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
