MISSOULA prefixes in area code 406
NANPA records 47 assigned NXX blocks to rate center MISSOULA in area code 406, 6.2% 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. 16 holders hold those blocks, the largest being QWEST CORPORATION (13), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MT (9), NEW CINGULAR WIRELESS PCS, LLC (5). The earliest assignment on record here is 2001-04-18 and the most recent 2026-06-05. 26 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
