STONEY CRK prefixes in area code 423

NANPA records 3 assigned NXX blocks to rate center STONEY CRK in area code 423, 0.4% of the 764 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 UNITED TELEPHONE-SOUTHEAST-TN DBA CENTURYLINK - TN (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (1), FRACTEL, LLC (1). The earliest assignment on record here is 2003-08-04 and the most recent 2020-07-15. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
