KALKASKA prefixes in area code 231
NANPA records 10 assigned NXX blocks to rate center KALKASKA in area code 231, 1.7% of the 572 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 OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2), MICHIGAN BELL TEL CO (1). The earliest assignment on record here is 2001-06-18 and the most recent 2022-02-14. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
