COLONILBCH prefixes in area code 804

NANPA records 6 assigned NXX blocks to rate center COLONILBCH in area code 804, 0.8% 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. 4 holders hold those blocks, the largest being VERIZON SOUTH, INC. - VA (CONTEL) (2), ONVOY, LLC - VA (2), IDT AMERICA, CORP. - VA (1). The earliest assignment on record here is 2009-01-07 and the most recent 2022-03-10. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
