ASTOR prefixes in area code 352

NANPA records 3 assigned NXX blocks to rate center ASTOR 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 ONVOY, LLC - FL (1), CENTURYLINK OF FLORIDA, INC. (UNITED) (1), LEVEL 3 COMMUNICATIONS, LLC - FL (1). The earliest assignment on record here is 2019-08-08 and the most recent 2022-12-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
