MARSHALLTN prefixes in area code 641

NANPA records 16 assigned NXX blocks to rate center MARSHALLTN in area code 641, 2.7% of the 584 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. 9 holders hold those blocks, the largest being QWEST CORPORATION (5), METROPCS, INC. (2), UNITED STATES CELLULAR - IA (2). The earliest assignment on record here is 2001-04-23 and the most recent 2024-03-08. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
