MARVELL prefixes in area code 870

NANPA records 3 assigned NXX blocks to rate center MARVELL 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. 2 holders hold those blocks, the largest being CSC VOICE, LLC (2), BRIGHTSPEED OF CENTRAL ARKANSAS, LLC (1). The earliest assignment on record here is 2014-01-03 and the most recent 2014-01-03. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
