WRIGHTSVL prefixes in area code 478

NANPA records 5 assigned NXX blocks to rate center WRIGHTSVL in area code 478, 1.1% 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. 4 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), BANDWIDTH.COM CLEC, LLC - GA (1), ONVOY, LLC - GA (1). The earliest assignment on record here is 2016-03-16 and the most recent 2021-01-15. 3 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 223, 501, 717 – overlay codes cover the same geography, so a rate center is served by all of them.
