ROSSTON prefixes in area code 870

NANPA records 3 assigned NXX blocks to rate center ROSSTON in area code 870, 0.4% of the 785 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 ONVOY, LLC - AR (1), BRIGHTSPEED OF CENTRAL ARKANSAS, LLC (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2018-09-21 and the most recent 2024-02-20. 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 940 – overlay codes cover the same geography, so a rate center is served by all of them.
