ALLIANCE prefixes in area code 308

NANPA records 6 assigned NXX blocks to rate center ALLIANCE in area code 308, 1.3% of the 465 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. 5 holders hold those blocks, the largest being QWEST CORPORATION (2), MOBIUS COMMUNICATIONS COMPANY - NE (1), N.E. COLORADO CELLULAR, INC. (1). The earliest assignment on record here is 2007-08-01 and the most recent 2010-02-23. 3 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 234, 330 – overlay codes cover the same geography, so a rate center is served by all of them.
