ANAMOSA prefixes in area code 319
NANPA records 9 assigned NXX blocks to rate center ANAMOSA in area code 319, 1.6% 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. 8 holders hold those blocks, the largest being UNITED STATES CELLULAR - IA (2), TELEPORT COMMUNICATIONS AMERICA, LLC - IA (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2008-12-17 and the most recent 2022-01-27. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
