CENTRAL CY prefixes in area code 270

NANPA records 11 assigned NXX blocks to rate center CENTRAL CY in area code 270, 1.4% 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 NEW CINGULAR WIRELESS PCS, LLC - GA (4), ONVOY, LLC - KY (3), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2). The earliest assignment on record here is 2001-11-15 and the most recent 2007-02-16. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 308, 319, 814 – overlay codes cover the same geography, so a rate center is served by all of them.
