CLIFTNFORG prefixes in area code 540

NANPA records 3 assigned NXX blocks to rate center CLIFTNFORG in area code 540, 0.4% of the 786 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 LUMOS TELEPHONE LLC (2), SHENTEL COMMUNICATIONS, LLC. - VA (1). The earliest assignment on record here is 2009-05-20 and the most recent 2009-05-20. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
