CEDAR SPG prefixes in area code 616

NANPA records 9 assigned NXX blocks to rate center CEDAR SPG in area code 616, 1.7% 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. 8 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (2), STRATUS NETWORKS (1), BANDWIDTH.COM CLEC, LLC - MI (1). The earliest assignment on record here is 2002-09-17 and the most recent 2021-03-19. 7 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 code 229 – overlay codes cover the same geography, so a rate center is served by all of them.
