GREENBACK prefixes in area code 865
NANPA records 5 assigned NXX blocks to rate center GREENBACK in area code 865, 1.0% of the 506 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 - TN (1), BANDWIDTH.COM CLEC, LLC - TN (1), FRACTEL, LLC (1). The earliest assignment on record here is 2006-12-27 and the most recent 2026-07-30. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
