HARDINSBG prefixes in area code 270

NANPA records 5 assigned NXX blocks to rate center HARDINSBG in area code 270, 0.7% 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. 5 holders hold those blocks, the largest being ONVOY, LLC - KY (1), BRANDENBURG TELECOM, LLC - KY (1), NEW CINGULAR WIRELESS PCS, LLC - GA (1). The earliest assignment on record here is 2002-04-02 and the most recent 2005-01-21. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
