GREATFALLS prefixes in area code 406
NANPA records 37 assigned NXX blocks to rate center GREATFALLS in area code 406, 4.9% 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. 18 holders hold those blocks, the largest being QWEST CORPORATION (11), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MT (6), NEW CINGULAR WIRELESS PCS, LLC (3). The earliest assignment on record here is 2001-07-12 and the most recent 2019-05-29. 24 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 codes 803, 839 – overlay codes cover the same geography, so a rate center is served by all of them.
