YAPHANK prefixes in area code 631

NANPA records 17 assigned NXX blocks to rate center YAPHANK in area code 631, 2.2% 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. 7 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (6), OMNIPOINT COMMUNICATIONS, INC. - NY (5), LEVEL 3 COMMUNICATIONS, LLC - NY (2). The earliest assignment on record here is 2002-09-19 and the most recent 2020-03-04. 15 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.
