LENOX prefixes in area code 641

NANPA records 5 assigned NXX blocks to rate center LENOX in area code 641, 0.9% 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (2), FRONTIER COMMUNICATIONS OF IOWA, INC. (1), LENOX MUNICIPAL COMMUNICATIONS UTILITY - IA (1). The earliest assignment on record here is 2004-11-11 and the most recent 2024-08-27. 2 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 229, 413 – overlay codes cover the same geography, so a rate center is served by all of them.
