10-Digit Dialing

Mandatory 10-digit dialing starts on October 24, 2021. Here’s what you need to know

The Federal Communications Commission (FCC) established “988” as a new nationwide three-digit phone number for the National Suicide Prevention Lifeline which will take effect by July 16, 2022. This change will provide an easy to remember, easy to dial phone number to reach suicide prevention and mental health counselors.

National Suicide Prevention Lifeline
1-800-273-TALK (8255)
“988” available by July 16, 2022

To support this change, on October 24, 2021, everyone with a telephone number in select states and area codes will be required to use 10-digit dialing to complete local calls. When an area code transitions to 10-digit dialing, you will no longer be able to complete a local call using seven-digits.

What is 10-digit dialing?

A 10-digit dialed phone call requires entering both the three-digit area code plus the seven-digit telephone number to complete the local call.

For example: 907-XXX-XXXX is considered 10-digit dialing. XXX-XXXX is considered seven-digit dialing.

Alaska and area code 907 is impacted and will require 10-digit dialing starting October 24, 2021.

What will you need to do?

In addition to changing the way you dial to make local calls (area code + telephone number) it is recommended that you check all services, devices and equipment that may be impacted by 10-digit dialing before October 24, 2021. This includes, but not limited to important safety and security equipment, such as medical alert devices, and alarm and security systems.

Here is a list of several services, devices, and equipment that may be impacted by 10-digit dialing:

  • Life safety systems or medical monitoring devices
  • Office Telephone Systems (PBXs)
  • Fax machines
  • Internet dial-up numbers
  • Fire or burglar alarm and security systems or gates
  • Speed dialers
  • Mobile or other wireless phone contact lists
  • Call forwarding settings
  • Voicemail services and other similar functions

For businesses, we also recommend checking your website and online business profiles that include click-to-call features, stationary including business cards, personal and business checks, and other unique areas where your contact information is listed.

How will this impact businesses?

If your company uses a PBX, SIP, or VoIP phone system, you may need to update or reprogram your phone system to support 10-digit dialing. We recommend making this change and to test your system prior to October 24, 2021, to avoid issues and interruptions in service.

If you need assistance updating or reprogramming your phone system, please contact your telecommunications provider. If you are an Alaska Communications customer, please contact our technical support team at 855-565-2556.
