OAKTOWN prefixes in area code 812

NANPA records 5 assigned NXX blocks to rate center OAKTOWN in area code 812, 0.6% 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 (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (1), LEVEL 3 COMMUNICATIONS, LLC - IN (1). The earliest assignment on record here is 2001-06-21 and the most recent 2002-08-20. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
