THOMASVL prefixes in area code 336

NANPA records 8 assigned NXX blocks to rate center THOMASVL in area code 336, 1.0% of the 783 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. 4 holders hold those blocks, the largest being NORTH STATE TELEPHONE CO. DBA NORTH STATE COMM (5), CENTURYLINK COMMUNICATIONS LLC - NC (1), METROPCS, INC. (1). The earliest assignment on record here is 2010-06-18 and the most recent 2016-02-12. 5 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 229, 334, 417, 743 – overlay codes cover the same geography, so a rate center is served by all of them.
