AMITYVILLE prefixes in area code 631

NANPA records 31 assigned NXX blocks to rate center AMITYVILLE in area code 631, 4.0% 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. 13 holders hold those blocks, the largest being OMNIPOINT COMMUNICATIONS, INC. - NY (12), VERIZON NEW YORK, INC. (6), CABLEVISION LIGHTPATH, INC. - NY (2). The earliest assignment on record here is 2001-05-16 and the most recent 2023-09-07. 28 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 516, 934 – overlay codes cover the same geography, so a rate center is served by all of them.
