FROSTPROOF prefixes in area code 863

NANPA records 7 assigned NXX blocks to rate center FROSTPROOF in area code 863, 1.5% of the 472 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. 6 holders hold those blocks, the largest being PEERLESS NETWORK OF FLORIDA, LLC - FL (2), FRACTEL, LLC (1), TELEPORT COMMUNICATIONS AMERICA, LLC - FL (1). The earliest assignment on record here is 2003-03-13 and the most recent 2021-03-18. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
