SLOATSBURG prefixes in area code 845

NANPA records 5 assigned NXX blocks to rate center SLOATSBURG in area code 845, 0.6% 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. 4 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (2), TC SYSTEMS, INC. - NY (1), UCOMTEL INC. (1). The earliest assignment on record here is 2001-03-06 and the most recent 2021-02-16. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
