Mandatory 10-Digit Dialing Coming to 406 Area Code

The Federal Communications Commission (FCC) has adopted 988 as a new three-digit number to be used nationwide to reach the National Suicide Prevention and Mental Health Crisis Lifeline, starting July 16, 2022. Customers must continue to dial 1-800-273-TALK to reach the Lifeline until July 16, 2022.

However, in order for 988 to work in our Montana area code (406), and in many other area codes throughout the country, 10-digit local dialing must first be implemented. That means you will need to change the way you dial local calls.

What will be the new dialing procedure to dial local numbers?

To complete all local calls, you will need to dial 406 and the seven-digit telephone number. This is known as 10-digit local dialing and will soon apply to all calls within your area code that are currently dialed with seven digits.

Who will be affected?

Everyone with a 406 telephone number will need to make the change from 7-digit local dialing to 10-digit local dialing.

When will the change begin?

  • Beginning April 24, 2021, you should begin dialing 10 digits (406 + telephone number) for all local calls. However, during a permissive period, if you forget and dial just 7 digits, your call will still be completed during this period.
  • Beginning October 24, 2021, you must dial 10 digits (406 + the local telephone number) for all local calls. On and after this date, local calls dialed with only 7-digits will not be completed, and a recording will inform you that your call cannot be completed as dialed. You must hang up and dial again using the area code and the 7-digit number.
  • Beginning July 16, 2022, dialing “988” will route your call to the National Suicide Prevention and Mental Health Crisis Lifeline.

What will you need to do?
In addition to changing the way you dial local calls, all services, automatic dialing equipment, or other types of equipment that are programmed to complete calls to 7-digit local numbers will need to be reprogrammed to complete calls to 10-digit numbers. Some examples are life safety systems or medical monitoring devices, PBXs, fax machines, Internet dial-up numbers, fire or burglar alarm and security systems or gates, speed dials, mobile or other wireless phone contact lists, call forwarding settings, voicemail services, personal or pet ID tags, and other similar functions. Businesses should be sure to revise their websites, personal and business stationery, advertising materials, personal and business checks, contact information, and other such items to ensure the area code is included.

What will remain the same?

  • Your telephone number, including the area code, will not change.
  • The price of a call, coverage area, or other rates and services will not change due to the dialing change.
  • What is a local call now will remain a local call regardless of the number of digits dialed.
  • You will continue to dial 1+ area code + telephone number for all long distance calls.
  • You can still dial just three digits to reach 711 (relay services) and 911 (emergency services).
  • Any 211, 311, 411, 511, 611, or 811 services available in your community can still be reached by dialing those three-digit codes.
  • The National Suicide Prevention Lifeline can still be reached by dialing 1-800-273-TALK (8255).
