COOKEVL SO prefixes in area code 931

NANPA records 3 assigned NXX blocks to rate center COOKEVL SO in area code 931, 0.6% of the 538 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 CHARTER IP ENABLED SERVICES, LLC (1), METROPCS, INC. (1), TWIN LAKES TEL. COOP. CORP. (1). The earliest assignment on record here is 2017-12-05 and the most recent 2022-06-14. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
