DUTTON prefixes in area code 616

NANPA records 11 assigned NXX blocks to rate center DUTTON in area code 616, 2.0% 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. 5 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (5), BANDWIDTH.COM CLEC, LLC - MI (2), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2006-02-15 and the most recent 2023-07-28. 8 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 406 – overlay codes cover the same geography, so a rate center is served by all of them.
