OLIVE HILL prefixes in area code 606

NANPA records 7 assigned NXX blocks to rate center OLIVE HILL in area code 606, 1.1% of the 639 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - KY (2), NEW CINGULAR WIRELESS PCS, LLC - DC (2), ONVOY, LLC - KY (1). The earliest assignment on record here is 2004-01-08 and the most recent 2024-06-20. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
