About Idaho Area Codes

With an estimated population of 1,704,042, Idaho is one of the smaller states in the North American Numbering Plan (NANP). The state is primarily in the Mountain Time Zone (MDT).

The largest cities in Idaho include Boise (pop. 389,280), Nampa (pop. 184,428), Coeur d'Alene (pop. 116,834), Meridian (pop. 114,161) and Idaho Falls (pop. 100,442) . Idaho has 44 counties spread across its territory. Each area code in ID covers a geographic region of the state, with some areas using overlay codes that share the same geographic territory as an existing area code.

When calling a Idaho phone number from outside the area code, you must dial the full 10-digit number: the 3-digit area code followed by the 7-digit local number. Many parts of Idaho now require 10-digit dialing even for local calls due to overlay area codes and the nationwide 988 Suicide & Crisis Lifeline implementation.
