NORCO prefixes in area code 985

NANPA records 6 assigned NXX blocks to rate center NORCO in area code 985, 1.3% of the 447 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. 5 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), LEVEL 3 COMMUNICATIONS, LLC - LA (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2001-10-02 and the most recent 2022-01-27. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
