PATCHOGUE prefixes in area code 631

NANPA records 26 assigned NXX blocks to rate center PATCHOGUE in area code 631, 3.3% of the 782 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. (8), NEW CINGULAR WIRELESS PCS, LLC - DC (5), CSC VOICE, LLC (2). The earliest assignment on record here is 2001-05-16 and the most recent 2020-03-09. 21 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 code 934 – overlay codes cover the same geography, so a rate center is served by all of them.
