PETOSKEY prefixes in area code 231

NANPA records 22 assigned NXX blocks to rate center PETOSKEY in area code 231, 3.8% 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. 13 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (4), NEW CINGULAR WIRELESS PCS, LLC - IL (4), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (2). The earliest assignment on record here is 2001-06-18 and the most recent 2023-01-06. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
