BRAZIL prefixes in area code 812

NANPA records 7 assigned NXX blocks to rate center BRAZIL in area code 812, 0.9% 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. 4 holders hold those blocks, the largest being FRONTIER NORTH, INC.. - IN (4), LEVEL 3 COMMUNICATIONS, LLC - IN (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-05-07 and the most recent 2010-01-28. 6 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 731, 930 – overlay codes cover the same geography, so a rate center is served by all of them.
