ROCHESTER prefixes in area code 248

NANPA records 23 assigned NXX blocks to rate center ROCHESTER in area code 248, 2.9% of the 784 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. 11 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (7), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (3), BANDWIDTH.COM CLEC, LLC - MI (2). The earliest assignment on record here is 2001-03-26 and the most recent 2016-07-25. 17 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 217, 270, 360, 412 – overlay codes cover the same geography, so a rate center is served by all of them.
