BILLINGS prefixes in area code 406
NANPA records 72 assigned NXX blocks to rate center BILLINGS in area code 406, 9.5% 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. 29 holders hold those blocks, the largest being QWEST CORPORATION (18), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MT (12), NEW CINGULAR WIRELESS PCS, LLC (7). The earliest assignment on record here is 2001-04-18 and the most recent 2024-12-23. 44 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 417, 580 – overlay codes cover the same geography, so a rate center is served by all of them.
