JUPITER prefixes in area code 561

NANPA records 42 assigned NXX blocks to rate center JUPITER in area code 561, 5.3% of the 786 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. 16 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (9), PAETEC ITEL, LLC (5), NEW CINGULAR WIRELESS PCS, LLC - GA (5). The earliest assignment on record here is 2003-09-05 and the most recent 2023-10-04. 34 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 code 728 – overlay codes cover the same geography, so a rate center is served by all of them.
