BOZEMAN prefixes in area code 406

NANPA records 32 assigned NXX blocks to rate center BOZEMAN in area code 406, 4.2% of the 754 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. 13 holders hold those blocks, the largest being QWEST CORPORATION (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MT (7), NEW CINGULAR WIRELESS PCS, LLC (4). The earliest assignment on record here is 2001-04-18 and the most recent 2024-12-18. 17 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
