Idaho Area Code Pieces of Information

The Idaho area code is a three-digit telephone area code in the North American Numbering Plan (NANP) for the state of Idaho. It was created on September 1, 1947, and was originally part of the Montana numbering plan area. On October 1, 1997, most of Idaho’s panhandle became part of Area code 208, which was split from Area code 406. The Idaho area code covers the entire state of Idaho. However, it is not contiguous with Area code 208. The two areas are separated by a “non-contiguous” portion of Area code 406 in Montana.

The Idaho area code is one of only two area codes (the other being Area code 986 in Hawaii) that does not have an overlay area code. This means that all telephone numbers in the Idaho area code are seven digits long and follow the standard NANP format of xxx-XXXX. It is one of the original 86 area codes created by AT&T. The 208 area code is split from the 406 area code.

The 208 area code has been home to some famous people including actors Aaron Paul and Bruce Willis, musician Carole King, and former U.S. Vice President Dick Cheney. Some notable businesses in the 208 area code include Albertsons, JCPenney, and Micron Technology.

The 208 area code is serviced by the following telephone companies:

  • AT&T
  • Verizon
  • T-Mobile
  • Sprint
  • Boost Mobile
  • U.S. Cellular
  • Idaho Telcom
  • Centurylink

Some of the smaller, regional carriers in the 208 area code include:

  • Custer Telephone Cooperative Association
  • Valley Internet
  • MeridianLink

The 208 area code is located in the Mountain Time Zone. The time zone for the 208 area code is GMT -7.
