GIRDWOOD prefixes in area code 907

NANPA records 4 assigned NXX blocks to rate center GIRDWOOD in area code 907, 0.6% of the 657 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. 2 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (2), ACS OF ANCHORAGE, INC. (2). The earliest assignment on record here is 2004-09-15 and the most recent 2007-09-17. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
