COLUMBIA prefixes in area code 839

NANPA records 27 assigned NXX blocks to rate center COLUMBIA in area code 839, 14.1% of the 192 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. 17 holders hold those blocks, the largest being ONVOY, LLC - SC (5), NEW CINGULAR WIRELESS PCS, LLC - GA (3), HD CARRIER LLC (2). The earliest assignment on record here is 2020-06-16 and the most recent 2026-10-28. 27 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 207, 223, 235, 252 – overlay codes cover the same geography, so a rate center is served by all of them.
