COEBURN prefixes in area code 276

NANPA records 6 assigned NXX blocks to rate center COEBURN 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. 6 holders hold those blocks, the largest being IP HORIZON LLC (1), VERIZON VIRGINIA, INC. (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - VA (1). The earliest assignment on record here is 2001-12-21 and the most recent 2024-10-21. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
