KEYSVILLE prefixes in area code 434

NANPA records 4 assigned NXX blocks to rate center KEYSVILLE in area code 434, 0.8% of the 509 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 UNITED STATES CELLULAR - VA (1), ONVOY SPECTRUM, LLC (1), VERIZON SOUTH, INC. - VA (CONTEL) (1). The earliest assignment on record here is 2014-09-16 and the most recent 2021-05-04. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
