SO BIG SPG prefixes in area code 970

NANPA records 3 assigned NXX blocks to rate center SO BIG SPG in area code 970, 0.4% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - CO (1), QWEST CORPORATION (1), SKYE TELECOM LLC DBA SKYETEL (1). The earliest assignment on record here is 2019-12-02 and the most recent 2021-10-01. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
