ROUGON prefixes in area code 225

NANPA records 5 assigned NXX blocks to rate center ROUGON in area code 225, 1.0% of the 501 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. 3 holders hold those blocks, the largest being ONVOY, LLC - LA (3), BANDWIDTH.COM CLEC, LLC - LA (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2011-07-08 and the most recent 2023-08-24. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
