WHITEFISH prefixes in area code 406
NANPA records 4 assigned NXX blocks to rate center WHITEFISH in area code 406, 0.5% 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. 3 holders hold those blocks, the largest being CENTURYTEL OF MONTANA, INC. DBA CENTURYLINK (2), LEVEL 3 COMMUNICATIONS, LLC - MT (1), CHARTER IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2023-02-17 and the most recent 2023-02-17. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
