JELLICO prefixes in area code 606

NANPA records 4 assigned NXX blocks to rate center JELLICO in area code 606, 0.6% 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. 4 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - KY (1), NUSO, LLC (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2013-10-18 and the most recent 2020-08-28. 3 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 423 – overlay codes cover the same geography, so a rate center is served by all of them.
