PIERMONT prefixes in area code 845

NANPA records 10 assigned NXX blocks to rate center PIERMONT in area code 845, 1.3% 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. (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NY (3), LEVEL 3 COMMUNICATIONS, LLC - NY (2). The earliest assignment on record here is 2001-03-06 and the most recent 2021-06-25. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 329, 603 – overlay codes cover the same geography, so a rate center is served by all of them.
