ORTONVILLE prefixes in area code 248

NANPA records 9 assigned NXX blocks to rate center ORTONVILLE in area code 248, 1.1% 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. 7 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (3), FRONTIER NORTH, INC. - MI (1), TELEPORT COMMUNICATIONS AMERICA, LLC - MI (1). The earliest assignment on record here is 2002-04-02 and the most recent 2016-11-30. 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 codes 320, 947 – overlay codes cover the same geography, so a rate center is served by all of them.
