RISING SUN prefixes in area code 812

NANPA records 3 assigned NXX blocks to rate center RISING SUN in area code 812, 0.4% 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 CENTURYLINK COMMUNICATIONS, LLC (1), BRIGHTSPEED OF INDIANA, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - IN (1). The earliest assignment on record here is 2001-06-27 and the most recent 2001-06-27. 3 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 410, 667, 930 – overlay codes cover the same geography, so a rate center is served by all of them.
