SWAINSBORO prefixes in area code 478

NANPA records 13 assigned NXX blocks to rate center SWAINSBORO in area code 478, 2.9% 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. 9 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - GA (3), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), NEW CINGULAR WIRELESS PCS, LLC - GA (2). The earliest assignment on record here is 2001-11-08 and the most recent 2020-12-21. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
