GUNNISON prefixes in area code 970

NANPA records 6 assigned NXX blocks to rate center GUNNISON in area code 970, 0.8% of the 786 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 QWEST CORPORATION (3), BANDWIDTH.COM CLEC, LLC - CO (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2005-03-01 and the most recent 2011-12-07. 4 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 435, 662 – overlay codes cover the same geography, so a rate center is served by all of them.
