COCOABEACH prefixes in area code 321
NANPA records 26 assigned NXX blocks to rate center COCOABEACH in area code 321, 5.2% of the 502 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. 10 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (6), LEVEL 3 COMMUNICATIONS, LLC - FL (5), ONVOY, LLC - FL (4). The earliest assignment on record here is 2001-11-08 and the most recent 2025-12-18. 21 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
