GRAVETTE prefixes in area code 479

NANPA records 4 assigned NXX blocks to rate center GRAVETTE in area code 479, 0.7% of the 569 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 AT&T ENTERPRISES, LLC (1), COMCAST IP PHONE, LLC (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2011-01-26 and the most recent 2011-03-22. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
