WILLISBURG prefixes in area code 859

NANPA records 3 assigned NXX blocks to rate center WILLISBURG in area code 859, 0.5% of the 563 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. 3 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1), LEVEL 3 COMMUNICATIONS, LLC - KY (1), ONVOY, LLC - KY (1). The earliest assignment on record here is 2006-10-25 and the most recent 2006-10-25. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
