DOWLING PK prefixes in area code 386

NANPA records 4 assigned NXX blocks to rate center DOWLING PK in area code 386, 0.9% 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 ONVOY, LLC - FL (1), FRACTEL, LLC (1), CORETEL FLORIDA, INC. - FL (1). The earliest assignment on record here is 2019-02-15 and the most recent 2021-04-29. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
