Telephone area code for Montana, United States
Montana numbering plan area and area code (blue)
Area code 406
is the telephone
area code
in the
North American Numbering Plan
for the entire
U.S. state
of
Montana
. It has been Montana's only area code since the
American Telephone and Telegraph Company
created a nationwide
telephone numbering plan
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 2031;
number pooling
has been implemented in response to increased demand and inefficient use of 406 numbering resources.
[1]
[2]
Prior to October 2021, area code 406 had telephone numbers assigned for the
central office code
988. In 2020,
988
was designated nationwide as a dialing code for the
National Suicide Prevention Lifeline
, which created a conflict for exchanges that permit
seven-digit dialing
. This area code was therefore scheduled to transition to
ten-digit dialing
by October 24, 2021.
