GRAY prefixes in area code 478
NANPA records 6 assigned NXX blocks to rate center GRAY 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. 4 holders hold those blocks, the largest being ONVOY, LLC - GA (2), GEORGIA WINDSTREAM, INC. (2), SOUTHERN COMMUNICATIONS SERVICES, INC. (1). The earliest assignment on record here is 2001-01-03 and the most recent 2023-06-27. 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 code 207 – overlay codes cover the same geography, so a rate center is served by all of them.
