RADCLIFF prefixes in area code 270

NANPA records 7 assigned NXX blocks to rate center RADCLIFF in area code 270, 0.9% 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. 3 holders hold those blocks, the largest being BRANDENBURG TEL. CO. (4), TWC IP ENABLED SERVICES, LLC (2), NEW CINGULAR WIRELESS PCS, LLC - GA (1). The earliest assignment on record here is 2001-05-03 and the most recent 2012-06-29. 4 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 code 364 – overlay codes cover the same geography, so a rate center is served by all of them.
