WARFIELD prefixes in area code 606

NANPA records 5 assigned NXX blocks to rate center WARFIELD in area code 606, 0.8% 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 LEVEL 3 COMMUNICATIONS, LLC - KY (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2003-04-23 and the most recent 2006-01-12. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
