BASILE prefixes in area code 337

NANPA records 3 assigned NXX blocks to rate center BASILE in area code 337, 0.5% of the 599 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - LA (1), BRIGHTSPEED OF LOUISIANA, LLC (1), COMMIO, LLC (1). The earliest assignment on record here is 2004-03-16 and the most recent 2023-08-22. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
