CHACKBAY prefixes in area code 985

NANPA records 4 assigned NXX blocks to rate center CHACKBAY in area code 985, 0.9% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - LA (2), PAETEC ITEL, LLC (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2005-06-11 and the most recent 2021-01-29. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
