FORTVALLEY prefixes in area code 478
NANPA records 6 assigned NXX blocks to rate center FORTVALLEY in area code 478, 1.3% 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. 5 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), LEVEL 3 COMMUNICATIONS, LLC - GA (1), ONVOY, LLC - GA (1). The earliest assignment on record here is 2006-07-06 and the most recent 2026-09-14. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
