AMHRSTFKLN prefixes in area code 413

NANPA records 7 assigned NXX blocks to rate center AMHRSTFKLN in area code 413, 1.2% 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. 5 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (2), NEW CINGULAR WIRELESS PCS, LLC - DC (2), ONVOY, LLC - MA (1). The earliest assignment on record here is 2008-10-10 and the most recent 2021-12-29. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
