IONIA prefixes in area code 616

NANPA records 10 assigned NXX blocks to rate center IONIA in area code 616, 1.8% of the 545 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. 7 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2003-05-01 and the most recent 2016-09-19. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 660, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
