MOUTHWILSN prefixes in area code 276

NANPA records 3 assigned NXX blocks to rate center MOUTHWILSN in area code 276, 0.8% 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. 3 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - VA (1), UNITED TELEPHONE-SOUTHEAST-VA DBA CENTURYLINK-VA (1), FRACTEL, LLC (1). The earliest assignment on record here is 2002-08-14 and the most recent 2020-09-08. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
