AMHERST prefixes in area code 440
NANPA records 9 assigned NXX blocks to rate center AMHERST in area code 440, 1.2% of the 757 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 BRIGHTSPEED OF OHIO, LLC (4), TWC IP ENABLED SERVICES, LLC (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (1). The earliest assignment on record here is 2013-06-25 and the most recent 2025-12-29. 8 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, 413, 434, 534 – overlay codes cover the same geography, so a rate center is served by all of them.
