SOUTHOSYKA prefixes in area code 985

NANPA records 3 assigned NXX blocks to rate center SOUTHOSYKA in area code 985, 0.7% 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 AT&T ENTERPRISES, LLC (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2011-08-03 and the most recent 2022-01-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
