FARMINGDL prefixes in area code 631

NANPA records 42 assigned NXX blocks to rate center FARMINGDL in area code 631, 5.4% 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. 8 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (18), CABLEVISION LIGHTPATH, INC. - NY (8), PAETEC ITEL, LLC (5). The earliest assignment on record here is 2011-09-30 and the most recent 2016-12-05. 34 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 363, 516, 732, 848 – overlay codes cover the same geography, so a rate center is served by all of them.
