MARTINSVL prefixes in area code 276

NANPA records 20 assigned NXX blocks to rate center MARTINSVL in area code 276, 5.3% 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. 9 holders hold those blocks, the largest being BRIGHTSPEED OF VIRGINIA, LLC (7), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - VA (3). The earliest assignment on record here is 2001-11-19 and the most recent 2023-03-16. 14 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 217, 765, 937 – overlay codes cover the same geography, so a rate center is served by all of them.
