BIGFORK prefixes in area code 406
NANPA records 3 assigned NXX blocks to rate center BIGFORK in area code 406, 0.4% 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 CHARTER IP ENABLED SERVICES, LLC (1), ONVOY, LLC - MT (1), CENTURYTEL OF MONTANA, INC. DBA CENTURYLINK (1). The earliest assignment on record here is 2006-02-28 and the most recent 2020-10-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 218 – overlay codes cover the same geography, so a rate center is served by all of them.
