HIGH SPG prefixes in area code 386

NANPA records 6 assigned NXX blocks to rate center HIGH SPG in area code 386, 1.3% of the 461 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 WINDSTREAM FLORIDA, INC. (2), ONVOY, LLC - FL (2), COMMIO, LLC (1). The earliest assignment on record here is 2011-11-10 and the most recent 2023-12-15. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
