UNADILLA prefixes in area code 478

NANPA records 3 assigned NXX blocks to rate center UNADILLA in area code 478, 0.7% 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. 3 holders hold those blocks, the largest being COMSOUTH TELENET, INC. - GA (1), WINDSTREAM GEORGIA COMMUNICATIONS CORP. (1), ONVOY, LLC - GA (1). The earliest assignment on record here is 2006-09-15 and the most recent 2006-09-15. 1 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 402, 607 – overlay codes cover the same geography, so a rate center is served by all of them.
