CROSSETT prefixes in area code 870

NANPA records 8 assigned NXX blocks to rate center CROSSETT in area code 870, 1.0% 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. 4 holders hold those blocks, the largest being WINDSTREAM ARKANSAS, INC. (5), LEVEL 3 COMMUNICATIONS, LLC - AR (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (1). The earliest assignment on record here is 2003-09-15 and the most recent 2016-12-22. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
