BENTON prefixes in area code 501

NANPA records 29 assigned NXX blocks to rate center BENTON in area code 501, 4.6% of the 631 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. 11 holders hold those blocks, the largest being SOUTHWESTERN BELL (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (4), T-MOBILE USA, INC. (4). The earliest assignment on record here is 2001-05-08 and the most recent 2026-10-21. 26 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 codes 270, 316, 318, 423 – overlay codes cover the same geography, so a rate center is served by all of them.
