MUSKEGON prefixes in area code 231
NANPA records 68 assigned NXX blocks to rate center MUSKEGON in area code 231, 11.9% 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. 16 holders hold those blocks, the largest being FRONTIER NORTH, INC. - MI (28), NEW CINGULAR WIRELESS PCS, LLC - IL (9), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (6). The earliest assignment on record here is 2001-02-21 and the most recent 2026-03-19. 46 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
