GRANITEFLS prefixes in area code 828

NANPA records 9 assigned NXX blocks to rate center GRANITEFLS in area code 828, 1.2% of the 724 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. 6 holders hold those blocks, the largest being BRIGHTSPEED OF NORTH CAROLINA, LLC (3), NEW CINGULAR WIRELESS PCS, LLC - GA (2), WINDSTREAM COMMUNICATIONS, INC. - NC (1). The earliest assignment on record here is 2002-09-24 and the most recent 2010-07-26. 8 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 320 – overlay codes cover the same geography, so a rate center is served by all of them.
