HERKIMER prefixes in area code 315

NANPA records 11 assigned NXX blocks to rate center HERKIMER in area code 315, 1.4% of the 781 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. 6 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (4), VERIZON NEW YORK, INC. (2), BANDWIDTH.COM CLEC, LLC - NY (2). The earliest assignment on record here is 2006-10-11 and the most recent 2018-05-03. 9 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 680 – overlay codes cover the same geography, so a rate center is served by all of them.
