COLUMBIACY prefixes in area code 260

NANPA records 9 assigned NXX blocks to rate center COLUMBIACY in area code 260, 2.0% of the 444 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 NEW CINGULAR WIRELESS PCS, LLC - IL (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (2), BRIGHTSPEED OF INDIANA, LLC (2). The earliest assignment on record here is 2001-08-09 and the most recent 2026-04-14. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
