ARKADLPHIA prefixes in area code 870

NANPA records 13 assigned NXX blocks to rate center ARKADLPHIA in area code 870, 1.7% 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. 9 holders hold those blocks, the largest being SOUTHWESTERN BELL (5), NEW CINGULAR WIRELESS PCS, LLC - IL (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (1). The earliest assignment on record here is 2001-05-08 and the most recent 2022-11-03. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
