KEOSAUQUA prefixes in area code 319

NANPA records 6 assigned NXX blocks to rate center KEOSAUQUA in area code 319, 1.1% of the 565 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 T-MOBILE USA, INC. (4), VAN BUREN TEL. CO., INC. (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (1). The earliest assignment on record here is 2005-11-11 and the most recent 2023-08-18. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
