TEMPERANCE prefixes in area code 734

NANPA records 9 assigned NXX blocks to rate center TEMPERANCE in area code 734, 1.3% of the 701 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. 6 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (2), INTERACTIVE SERVICES NETWORK, INC. (2), FRONTIER NORTH, INC. - MI (2). The earliest assignment on record here is 2005-09-13 and the most recent 2005-09-13. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
