HAWTHORNE prefixes in area code 352

NANPA records 5 assigned NXX blocks to rate center HAWTHORNE in area code 352, 0.7% of the 711 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. 4 holders hold those blocks, the largest being ONVOY, LLC - FL (2), PAETEC ITEL, LLC (1), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (1). The earliest assignment on record here is 2003-01-07 and the most recent 2023-01-10. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 310, 424, 775, 862 – overlay codes cover the same geography, so a rate center is served by all of them.
