NYACK prefixes in area code 845

NANPA records 18 assigned NXX blocks to rate center NYACK in area code 845, 2.3% 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. 11 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (4), OMNIPOINT COMMUNICATIONS, INC. - NY (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NY (2). The earliest assignment on record here is 2001-01-15 and the most recent 2023-06-26. 11 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, 914 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
