New Idaho Area Code Overlay and 10-digit Dialing

Updated July 5, 2017


Beginning August 5, callers in Idaho will have to dial the area code along with the seven-digit telephone number to make a local call.

The Idaho Public Utilities Commission approved a new area code for the state of Idaho in December of 2015 to address the need for additional numbers.  To implement the new area code, the Commission also approved mandatory 10-digit dialing for all of Idaho.

New area code overlay

The new area code, 986, will overlay all of Idaho.  As numbers are needed, assignments may be made out of the new 986 area code.

New dialing procedure

On August 5, all calls made within Idaho must be placed using the 10 digit telephone number.  If consumers dial only seven digits, the call will not complete and the caller will hear an announcement instructing them to redial including the area code.

Important facts for consumers

•    Current telephone number, including current area code, will not change.
•    Consumers will continue to dial 1 + area code + telephone number to complete long distance calls.
•    A local call will remain a local call.
•    The price of a call, coverage area, or other rates and services will not change.
•    Calling 911 will not change.
•    Consumers will continue to dial three digits to reach 211 and 811, as well as 311 and 511, where available.

What you need to do

It is important that consumers confirm that all services, automatic dialing equipment, applications, software, or other types of equipment recognize the new 986 area code and are programmed to use the new dialing procedure.  This may include life-safety systems, fax machines, internet dial-up numbers, alarm and security systems*, gates, ankle monitors, speed dialers, mobile phone contact lists, call forwarding settings, voicemail services, and similar functions.

Consumers should check business stationery, advertising materials, personal checks, and personal or pet ID tags to ensure the area code is included in the telephone number.

*Please note that Silver Star security customers already have 10-digit numbers programmed into security equipment that was installed by Silver Star or that currently subscribes to Silver Star monitoring service. If you have special panic programming to contact the local authorities, you should double check that all 10 digits of the number have been included. 911 will still work with just three digits.
