KALONA prefixes in area code 319

NANPA records 3 assigned NXX blocks to rate center KALONA in area code 319, 0.5% 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. 2 holders hold those blocks, the largest being MCC TELEPHONY LLC (2), KALONA COOP. TEL. CO. (1). The earliest assignment on record here is 2006-11-29 and the most recent 2010-03-19. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
