IDAHOFALLS prefixes in area code 208

NANPA records 51 assigned NXX blocks to rate center IDAHOFALLS in area code 208, 6.5% of the 785 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. 10 holders hold those blocks, the largest being QWEST CORPORATION (21), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - ID (11), NEW CINGULAR WIRELESS PCS, LLC (5). The earliest assignment on record here is 2001-03-08 and the most recent 2021-03-26. 28 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 986 – overlay codes cover the same geography, so a rate center is served by all of them.
