NANPA records 5 assigned NXX blocks to rate center CATLETTSBG 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. 2 holders hold those blocks, the largest being WINDSTREAM KENTUCKY EAST, INC. - LEXINGTON (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2005-04-12 and the most recent 2013-11-14. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
