SMITHS GRV prefixes in area code 270

NANPA records 3 assigned NXX blocks to rate center SMITHS GRV in area code 270, 0.4% of the 769 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. 2 holders hold those blocks, the largest being WINDSTREAM KENTUCKY EAST, INC. - LONDON (2), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2007-10-25 and the most recent 2015-06-17. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
