PETERSBURG prefixes in area code 812

NANPA records 9 assigned NXX blocks to rate center PETERSBURG in area code 812, 1.1% 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. 6 holders hold those blocks, the largest being FRONTIER NORTH, INC. - IN (3), LEVEL 3 COMMUNICATIONS, LLC - IN (2), ONVOY, LLC - IN (1). The earliest assignment on record here is 2001-05-07 and the most recent 2002-08-20. 9 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, 304, 402, 447 – overlay codes cover the same geography, so a rate center is served by all of them.
