Mandatory 10-Digit Dialing

Get Ready to Change the Way You Dial Your Calls!

Starting July 16, 2022, the Federal Communications Commission (FCC) will make 988 the three-digit number people may call to reach the National Suicide Prevention and Mental Health Crisis Lifeline. Until that date, please call 1.800.273.TALK (8255) to reach the Lifeline.

To make 988 work in your area code, 10-digit or 11-digit local dialing will go into effect in these area codes:

State Area Codes State Area Codes
Alabama 251 Minnesota 218, 952
Arizona 928 Mississippi 662
*California 209, 530, 562, 626, 707, 949, 951 Nevada 775
Florida 941 New Mexico 505
Georgia 706, 912 New York 607, 716, 845
Iowa 515 Ohio 440, 513

What will be the new dialing procedure?

To complete all local calls, you will need to dial area code + telephone number. *California and *Illinois customers will need to dial 1 + area code + telephone number. This applies to all calls within your area code that you currently dial 7 digits to reach.

Who will be affected?

Anyone with a telephone number from an area code listed in the table above must make this change from 7-digit local dialing to 10-digit local dialing or 11-digit local dialing (in California and Illinois).

When will the change begin?

Beginning April 24, 2021, you should begin dialing 10 digits (area code + telephone number) or 11 digits (1 + area code + telephone number in California and Illinois) for all local calls. If you forget and dial just 7 digits, your call will still be completed.

Beginning October 24, 2021, you must dial 10 digits (area code + telephone number) or 11 digits (1 + area code + telephone number in California and Illinois) for all local calls. On and after this date, local calls dialed with only 7 digits may 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 + 7-digit number or 1 + area code + 7-digit number (in California and Illinois).

Beginning July 16, 2022, dialing 988 will reach 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 or 11-digit numbers (in California and Illinois). 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 dialers
  • mobile or other wireless phone contact lists
  • call forwarding settings
  • voicemail services and other similar functions

Be sure to check your website, personal and business stationery, advertising materials, personal and business checks, contact information, your personal or pet ID tags, and other such items to ensure the area code is included.

What will remain the same?

  • Your telephone number, including current 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 their three-digit codes.
  • The National Suicide Prevention Lifeline can still be reached by dialing 1.800.273.TALK (8255).
