DUBLIN prefixes in area code 478

NANPA records 26 assigned NXX blocks to rate center DUBLIN in area code 478, 5.8% of the 446 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. 12 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - GA (7), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (5), POWERTEL ATLANTA LICENSES, INC. (4). The earliest assignment on record here is 2001-02-28 and the most recent 2025-02-14. 14 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 215, 231, 254, 267 – overlay codes cover the same geography, so a rate center is served by all of them.
