HOWEYINHLS prefixes in area code 352

NANPA records 3 assigned NXX blocks to rate center HOWEYINHLS in area code 352, 0.4% of the 711 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. 3 holders hold those blocks, the largest being CENTURYLINK OF FLORIDA, INC. (UNITED) (1), ONVOY, LLC - FL (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2016-03-16 and the most recent 2021-03-04. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
