SNEEDVILLE prefixes in area code 423

NANPA records 7 assigned NXX blocks to rate center SNEEDVILLE in area code 423, 0.9% 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. 7 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (1), ONVOY, LLC - TN (1), AT&T - LOCAL (1). The earliest assignment on record here is 2002-04-30 and the most recent 2021-05-17. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
