AMHERST prefixes in area code 413

NANPA records 27 assigned NXX blocks to rate center AMHERST in area code 413, 4.5% of the 605 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. 9 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (9), VERIZON NEW ENGLAND INC. (9), ONVOY, LLC - MA (2). The earliest assignment on record here is 2003-11-10 and the most recent 2021-12-29. 19 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 308, 434, 440, 534 – overlay codes cover the same geography, so a rate center is served by all of them.
