GLENNALLEN prefixes in area code 907

NANPA records 5 assigned NXX blocks to rate center GLENNALLEN in area code 907, 0.8% 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. 4 holders hold those blocks, the largest being GCI COMMUNICATION CORP. DBA GENERAL COMMUNICATION (2), COPPER VALLEY CELLULAR (1), NEW CINGULAR WIRELESS PCS, LLC (1). The earliest assignment on record here is 2006-02-21 and the most recent 2008-11-20. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
