PUXICO prefixes in area code 573

NANPA records 3 assigned NXX blocks to rate center PUXICO in area code 573, 0.4% 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. 2 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), BANDWIDTH.COM CLEC, LLC - MO (1). The earliest assignment on record here is 2003-01-10 and the most recent 2017-01-12. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
