ARKANSASCY prefixes in area code 620

NANPA records 10 assigned NXX blocks to rate center ARKANSASCY in area code 620, 1.4% of the 705 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. 5 holders hold those blocks, the largest being SOUTHWESTERN BELL (4), LEVEL 3 COMMUNICATIONS, LLC - KS (2), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2001-06-07 and the most recent 2024-03-06. 9 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 870 – overlay codes cover the same geography, so a rate center is served by all of them.
