Area code 406 - wikipedia Area code 406 The map to the right is clickable ; click on an area code to go to the page for that code. Coordinates : 47 ° 00 ′ 01 '' N 109 ° 45 ′ 04 '' W ﻿ / ﻿ 47.00028 ° N 109.75111 ° W ﻿ / 47.00028 ; - 109.75111 ﻿ ( State of Montana ) Area code 406 is the telephone area code covering the entire state of Montana. It has been Montana 's area code since area codes were created in 1947. As of 2013, there were 1.7 million lines served by 47 carriers ; all but two wireline providers support local number portability ( the exceptions are small rural independents Hot Springs Telephone Company and Northern Telephone Cooperative ). Sufficient available codes for new exchanges in the 406 area code exist to meet anticipated demand until 2019 ; number pooling has been implemented in response to increased demand and inefficient use of 406 numbering resources.
