COLUMBUS prefixes in area code 812

NANPA records 28 assigned NXX blocks to rate center COLUMBUS in area code 812, 3.6% 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. 10 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (12), NEW CINGULAR WIRELESS PCS, LLC - IL (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (3). The earliest assignment on record here is 2001-04-17 and the most recent 2017-08-14. 17 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, 270, 274, 364 – overlay codes cover the same geography, so a rate center is served by all of them.
