CHARLESTN prefixes in area code 930

NANPA records 5 assigned NXX blocks to rate center CHARLESTN in area code 930, 3.1% of the 159 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. 5 holders hold those blocks, the largest being ONVOY, LLC - IN (1), TELEPORT COMMUNICATIONS AMERICA, LLC - IN (1), NEW CINGULAR WIRELESS PCS, LLC - GA (1). The earliest assignment on record here is 2017-05-22 and the most recent 2020-08-28. 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 603, 617, 812, 857 – overlay codes cover the same geography, so a rate center is served by all of them.
