HADDOCK prefixes in area code 478

NANPA records 3 assigned NXX blocks to rate center HADDOCK in area code 478, 0.7% of the 446 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 ONVOY, LLC - GA (2), GEORGIA WINDSTREAM, INC. (1). The earliest assignment on record here is 2021-07-29 and the most recent 2021-07-29. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
