NOSIOUX CY prefixes in area code 605
NANPA records 10 assigned NXX blocks to rate center NOSIOUX CY in area code 605, 1.3% of the 745 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. 6 holders hold those blocks, the largest being LONG LINES METRO, LLC - SD (3), QWEST CORPORATION (2), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2006-12-28 and the most recent 2022-06-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
