MAUMELLE prefixes in area code 501

NANPA records 3 assigned NXX blocks to rate center MAUMELLE in area code 501, 0.5% 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. 3 holders hold those blocks, the largest being WINDSTREAM ARKANSAS, INC. (1), TELEPORT COMMUNICATIONS AMERICA, LLC - AR (1), ONVOY, LLC - AR (1). The earliest assignment on record here is 2020-06-15 and the most recent 2025-09-11. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
