MELBOURNE prefixes in area code 321
NANPA records 85 assigned NXX blocks to rate center MELBOURNE in area code 321, 16.9% 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. 22 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (20), OMNIPOINT MIAMI E LICENSE, LLC (7), NEW CINGULAR WIRELESS PCS, LLC - GA (7). The earliest assignment on record here is 2001-03-22 and the most recent 2026-08-19. 68 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 641, 870 – overlay codes cover the same geography, so a rate center is served by all of them.
