10-Digit Dialing

March 19, 2021

Starting October 24, 2021, the FCC has mandated all phone calls will require dialing the full 10-digit phone number, including area code. This means all Alaskans, regardless of their service provider, will need to dial 907 before seven-digit phone numbers even when making a local phone call.

Beginning April 24, phone calls can be made using full 10-digit phone numbers. After April 24, and before October 24, 2021, is a great time to update your contacts, and reprogram any call forwarding to lead with 907.

10-Digit Dialing FAQs

What is 10-digit dialing?

Ten-digit dialing means that you need to dial all 10 digits of a phone number, including the area code. It doesn’t matter if the call is local or not. For example, if you currently dial 444-4444 to reach a local number, after 10-digit dialing goes into effect, you will need to dial 907-444-4444. This applies to wireless and land line calls.


Why is Alaska switching to 10-digit dialing?

The Federal Communications Commission (FCC) mandated that all states that have not yet switched to 10-digit dialing, must do so by October 24, 2021. This mandate applies to all mobile and landline carriers. GCI is making this switch in accordance with the FCC mandate.


When is Alaska switching to 10-digit dialing?

Starting on April 24, 2021 you will be able to use 10-digit dialing for local numbers. You will also still be able to use seven-digit dialing. This is a good time for you to update saved numbers. Ten-digit dialing will go into effect on October 24, 2021. On this date, to complete a local call you will be required to dial 10 digits.


What does this mean for my business phones?

It depends. At the least, you will need to update saved local numbers and call forwarding features. Depending on the age and type of your business phone system, you may need complex updates that require a skilled technician.


If I am a GCI Managed Voice customer, will GCI do this work for me?

Yes. If you are a GCI customer all Managed Voice lines will be updated by GCI. No action is required by you. However, if you have additional lines that use a different product, you will still need to update those lines.


How can I determine if my phone system needs complex updates?

Complete this self-assessment and contact your Account Manager. The assessment will help GCI understand what work needs to be done. If necessary, GCI can refer you to a trusted third-party resource to complete the work. In some rare cases, aging phone systems may not be compatible with 10-digit dialing and will need to be replaced.


Does this impact safety systems like fire alarms and security systems?

It depends. 9-1-1 calls will not be impacted by 10-digit dialing. However, many fire alarms and security systems in office buildings use an auto-dialer to call a local service provider. The provider determines the appropriate next action. Please contact your fire alarm service company and security system service company to ensure your systems are configured for 10-digit dialing.


Does this impact elevator emergency calls?

Yes. The emergency phone in your elevator will be impacted. If your elevator has an auto-call feature to a local number, it will need to be reprogrammed. Please contact your elevator service company to ensure your system is configured for 10-digit dialing.


Will 9-1-1 be impacted by 10-digit dialing?

No. 9-1-1 will not be impacted.
