SLATE HILL prefixes in area code 845

NANPA records 3 assigned NXX blocks to rate center SLATE HILL in area code 845, 0.4% of the 783 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 CITIZENS TELECOMM CO OF NY DBA FRONTIER COMM OF NY (1), CSC VOICE, LLC (1), BOOST SUBSCRIBERCO L.L.C. (1). The earliest assignment on record here is 2004-08-20 and the most recent 2023-05-02. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
