SARDIS prefixes in area code 478

NANPA records 4 assigned NXX blocks to rate center SARDIS in area code 478, 0.9% 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. 4 holders hold those blocks, the largest being CENTURYLINK COMMUNICATIONS, LLC (1), PINELAND COMMUNICATIONS, INC. - GA (1), ONVOY, LLC - GA (1). The earliest assignment on record here is 2015-09-21 and the most recent 2022-10-21. 4 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 304, 662, 681, 731 – overlay codes cover the same geography, so a rate center is served by all of them.
