NANPA records 3 assigned NXX blocks to rate center BIG SKY in area code 406, 0.4% of the 754 blocks assigned in the code.

COOP., INC. (2), MONTANA OPTICOM, LLC - MT (1). The earliest assignment on record here is 2006-07-11 and the most recent 2006-07-11. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
