CHARLES CY prefixes in area code 804

NANPA records 5 assigned NXX blocks to rate center CHARLES CY in area code 804, 0.6% of the 781 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 LEVEL 3 COMMUNICATIONS, LLC - VA (1), CORETEL VIRGINIA, LLC - VA (1), VERIZON VIRGINIA, INC. (1). The earliest assignment on record here is 2014-06-10 and the most recent 2021-08-26. 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 641, 686 – overlay codes cover the same geography, so a rate center is served by all of them.
