CASTILE prefixes in area code 585
NANPA records 3 assigned NXX blocks to rate center CASTILE in area code 585, 0.4% of the 676 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 FRONTIER TELEPHONE OF ROCHESTER, INC. (1), ONVOY, LLC- NY (1), COMMIO, LLC (1). The earliest assignment on record here is 2017-03-17 and the most recent 2021-09-24. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
