OPELOUSAS prefixes in area code 337

NANPA records 21 assigned NXX blocks to rate center OPELOUSAS in area code 337, 3.5% 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. 9 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (5), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - LA (3). The earliest assignment on record here is 2001-09-17 and the most recent 2023-06-30. 15 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
