ROCKYMOUNT prefixes in area code 540

NANPA records 13 assigned NXX blocks to rate center ROCKYMOUNT in area code 540, 1.7% of the 786 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. 7 holders hold those blocks, the largest being BRIGHTSPEED OF VIRGINIA, LLC (4), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (3), UNITED STATES CELLULAR - VA (2). The earliest assignment on record here is 2002-06-25 and the most recent 2020-02-18. 10 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 code 252 – overlay codes cover the same geography, so a rate center is served by all of them.
