Idaho has long been one of 12 states having just one area code. That changes in 2017.
Just about the time that all of the available area code 208 phone numbers run out, Idaho will start issuing 986 numbers. Unlike Washington, which assigns area codes based on geographic location, Idaho will assign 986 to all new numbers overlaid across the state.
Existing phone customers will keep their area code 208 numbers.
After 16 months of phasing in the new 986 numbers, mandatory 10-digit dialing starts in the fourth quarter of 2017. Read the Spokesman-Review article.
