10-Digit Dialing Will Be Required Starting July 6th.


On July 6, 2022, 10-digit local calling will be required for the ITC service area, and it will become mandatory nationwide on July 16, 2022. The price of the call, coverage area, EAS, or other rates and services will not change due to the dialing change.

The FCC has adopted 988 as the designated three-digit dialing code to route callers to the National Suicide Prevention Lifeline. For 988 to work, 10-digit local dialing must first be implemented. Starting July 16, 2022, 10-digit dialing will become mandatory nationwide, and calling 988 will route your call to the National Suicide Prevention and Mental Health Crisis Lifeline.

Now through July 5, 2022:

  • 10-digit dialing (area code + telephone number) is allowed and should be used
  • 7-digit dialing may still work

Starting July 6, 2022:

  • 10-digit dialing will be required for local calls.
  • 7-digit dialing will no longer work. A recording will inform you to hang up and dial again using the area code + 7 digits.

Business Customers

Businesses have a few other items to address for 10-digit dialing. In addition to changing your dialing patterns, all services, automatic dialing equipment, or other types of equipment programmed to complete local calls using only 7-digit numbers will need to be reprogrammed to complete calls to 10-digit numbers.

Some examples are:

  • Phone System Speed Dial Settings
  • Phone System Call Forwarding Buttons
  • Fax Machines
  • Fire Alarm or Security Systems
  • Auto Dialers – Ex: Sensaphones
  • Mobile Phone Contact Lists  
  • Voicemail Services

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