BONNETERRE prefixes in area code 573

NANPA records 4 assigned NXX blocks to rate center BONNETERRE in area code 573, 0.5% 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. 4 holders hold those blocks, the largest being SOUTHWESTERN BELL (1), AT&T ENTERPRISES, LLC (1), TELEPORT COMMUNICATIONS AMERICA, LLC - MO (1). The earliest assignment on record here is 2011-04-27 and the most recent 2024-03-29. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
