TAZEWELL prefixes in area code 276

NANPA records 6 assigned NXX blocks to rate center TAZEWELL in area code 276, 1.6% of the 374 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 VERIZON SOUTH, INC. - VA (2), COMCAST IP PHONE, LLC (1), ONVOY, LLC - VA (1). The earliest assignment on record here is 2013-02-22 and the most recent 2024-06-17. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
