ASH FLAT prefixes in area code 870

NANPA records 4 assigned NXX blocks to rate center ASH FLAT in area code 870, 0.5% 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 TELEPORT COMMUNICATIONS AMERICA, LLC - AR (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2003-08-05 and the most recent 2024-08-08. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
