Idaho - 208 Area Code
You can locate Idaho on the map to the east of Oregon and Washington state. On the other side you find Montana and Wyoming. Though the population is low in this state, there are a few well populated urban areas that include Boise, Pocatello, and Twin Falls. These are the most populated areas using the 208 area code. If you think the unknown number coming into your phone line is from a business, they may very well be from one of these three cities.
Though lower population numbers have kept the 208 area code the only one within the state thus far, there were thoughts to the contrary at one time. Some thought the state of Idaho would run out of numbers by the year 2003, and that would mean a new area code would be needed. That turned out to be untrue, and the plans for a new code were shelved. Yet again thoughts turned to a new code, as the thinking was that the state would be out of numbers by 2010, but the pooling of numbers in the state shelved those plans yet again.
