OTTUMWA prefixes in area code 641
NANPA records 15 assigned NXX blocks to rate center OTTUMWA in area code 641, 2.6% 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (3), QWEST CORPORATION (3). The earliest assignment on record here is 2001-02-09 and the most recent 2024-11-11. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
