BLUEFIELD prefixes in area code 681
NANPA records 12 assigned NXX blocks to rate center BLUEFIELD in area code 681, 2.4% of the 499 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. 11 holders hold those blocks, the largest being MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2), ONVOY, LLC - WV (1), CITIZENS TEL CO OF WV DBA FRONTIER OF WV (1). The earliest assignment on record here is 2012-05-07 and the most recent 2026-07-08. 12 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 codes 276, 304 – overlay codes cover the same geography, so a rate center is served by all of them.
