FOWLERVL prefixes in area code 517

NANPA records 11 assigned NXX blocks to rate center FOWLERVL in area code 517, 1.8% of the 616 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (3), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - MI (1). The earliest assignment on record here is 2001-10-30 and the most recent 2023-03-16. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
