REED CITY prefixes in area code 231

NANPA records 7 assigned NXX blocks to rate center REED CITY in area code 231, 1.2% 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (3), BANDWIDTH.COM CLEC, LLC - MI (1), LEVEL 3 COMMUNICATIONS, LLC - MI (1). The earliest assignment on record here is 2001-05-18 and the most recent 2002-08-30. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
