NEWHAMPTON prefixes in area code 641

NANPA records 12 assigned NXX blocks to rate center NEWHAMPTON in area code 641, 2.1% of the 584 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. 3 holders hold those blocks, the largest being UNITED STATES CELLULAR - IA (9), WINDSTREAM IOWA COMMUNICATIONS, INC. - SYSTEMS (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (1). The earliest assignment on record here is 2004-05-06 and the most recent 2025-03-21. 12 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 660 – overlay codes cover the same geography, so a rate center is served by all of them.
