MONTROSS prefixes in area code 804

NANPA records 3 assigned NXX blocks to rate center MONTROSS in area code 804, 0.4% 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. 3 holders hold those blocks, the largest being PEERLESS NETWORK OF VIRGINIA, LLC - VA (1), VERIZON SOUTH, INC. - VA (CONTEL) (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2016-01-04 and the most recent 2021-05-26. 3 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 code 686 – overlay codes cover the same geography, so a rate center is served by all of them.
