E HAMPTON prefixes in area code 631

NANPA records 9 assigned NXX blocks to rate center E HAMPTON in area code 631, 1.2% 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. 5 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (3), CSC VOICE, LLC (3), PEERLESS NETWORK OF NEW YORK, LLC - NY (1). The earliest assignment on record here is 2004-10-13 and the most recent 2016-06-03. 7 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 860, 934, 959 – overlay codes cover the same geography, so a rate center is served by all of them.
