GENEVA prefixes in area code 440

NANPA records 5 assigned NXX blocks to rate center GENEVA in area code 440, 0.7% 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. 4 holders hold those blocks, the largest being WINDSTREAM WESTERN RESERVE, INC. (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1), ONVOY, LLC - OH (1). The earliest assignment on record here is 2002-06-28 and the most recent 2021-05-10. 4 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 260, 315, 321, 331 – overlay codes cover the same geography, so a rate center is served by all of them.
