MUSCATINE prefixes in area code 563

NANPA records 19 assigned NXX blocks to rate center MUSCATINE in area code 563, 4.9% of the 388 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 QWEST CORPORATION (5), T-MOBILE USA, INC. (3), ONVOY, LLC - IA (2). The earliest assignment on record here is 2001-06-05 and the most recent 2024-06-26. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
