LEONVILLE prefixes in area code 337

NANPA records 3 assigned NXX blocks to rate center LEONVILLE 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 CHARTER IP ENABLED SERVICES, LLC (1), IP HORIZON LLC (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2008-07-09 and the most recent 2024-04-05. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
