COLUMBIA prefixes in area code 573
NANPA records 59 assigned NXX blocks to rate center COLUMBIA in area code 573, 7.5% of the 786 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. 14 holders hold those blocks, the largest being BRIGHTSPEED OF MISSOURI, LLC (23), T-MOBILE USA, INC. (9), NEW CINGULAR WIRELESS PCS, LLC - IL (8). The earliest assignment on record here is 2001-05-22 and the most recent 2024-07-03. 38 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.
