CAMDENTON prefixes in area code 573

NANPA records 8 assigned NXX blocks to rate center CAMDENTON in area code 573, 1.0% 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. 5 holders hold those blocks, the largest being SOUTHWESTERN BELL (3), UNITED STATES CELLULAR - MO (2), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2011-02-17 and the most recent 2024-03-29. 7 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 code 235 – overlay codes cover the same geography, so a rate center is served by all of them.
