10-Digit Dialing

10-Digit Dialing Requirements

What changes are happening to the way a call is dialed?

In support of the National Suicide Prevention Hotline, you will be required to dial 10-digits (area code + telephone number) for local calls on your telephone lines. 10-digit local dialing will be enabled on April 24, 2021 at the start of the permissive dialing period. During the permissive period until October 24, 2021 you may dial either 7 or 10 digits for local calls. After October 24, 2021, 7-digit local calls will be rejected, and you must dial 10-digits for local calls.

Why are we making this change?

On July 16, 2020, the Federal Communications Commission (FCC) adopted an Order approving a new three-digit dialing code to reach National Suicide Prevention Lifeline. Telecommunication carriers are making necessary changes to ensure callers can dial 988 to reach the National Suicide Prevention Lifeline beginning July 16, 2022. Until then, you can reach the National Suicide Prevention Lifeline by dialing 800-273-TALK (8255).

What other changes need to be made?

Important safety and security equipment, such as medical alert devices, and alarm and security systems must be programmed to use 10-digit dialing. Many systems operate on 10-digit dialing by default, but some older equipment may still use seven-digits. Please contact your medical alert or security provider if you are not sure whether your equipment needs to be reprogrammed to accommodate the upcoming change to 10-digit local dialing. Any needed reprogramming of alarm and home security equipment should be done during the permissive dialing period between April 24, 2021 and October 24, 2021 to avoid interruption of services. Some other examples of services that may need to be re-programmed are:

  • 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
