LOUISIANA prefixes in area code 573
NANPA records 4 assigned NXX blocks to rate center LOUISIANA 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 LEVEL 3 COMMUNICATIONS, LLC - MO (1), ONVOY, LLC - MO (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2002-05-07 and the most recent 2022-01-13. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
