FORTBRANCH prefixes in area code 812

NANPA records 4 assigned NXX blocks to rate center FORTBRANCH in area code 812, 0.5% of the 785 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. 3 holders hold those blocks, the largest being FRONTIER NORTH, INC. - IN (2), TWC IP ENABLED SERVICES, LLC (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (1). The earliest assignment on record here is 2002-04-04 and the most recent 2002-04-04. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
