RURALRTRET prefixes in area code 276

NANPA records 4 assigned NXX blocks to rate center RURALRTRET in area code 276, 1.1% 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 (2), TELNYX LLC (1), UNITED TELEPHONE-SOUTHEAST-VA DBA CENTURYLINK-VA (1). The earliest assignment on record here is 2002-08-15 and the most recent 2021-03-23. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
