FENTON prefixes in area code 810

NANPA records 15 assigned NXX blocks to rate center FENTON in area code 810, 2.9% of the 509 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. 10 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (3), CHARTER IP ENABLED SERVICES, LLC (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (2). The earliest assignment on record here is 2002-03-27 and the most recent 2024-02-16. 12 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 337, 515, 636 – overlay codes cover the same geography, so a rate center is served by all of them.
