HUNTINGTON prefixes in area code 631

NANPA records 34 assigned NXX blocks to rate center HUNTINGTON in area code 631, 4.3% 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. 10 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (11), NEW CINGULAR WIRELESS PCS, LLC - DC (8), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NY (4). The earliest assignment on record here is 2001-02-14 and the most recent 2024-11-11. 20 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 203, 260, 413, 475 – overlay codes cover the same geography, so a rate center is served by all of them.
