10-Digit Dialing Required for Local Calls

The Federal Communications Commission (FCC) has adopted 988 as a new three-digit number to be used nationwide to reach the National Suicide Prevention and Mental Health Crisis Lifeline, effective July 16, 2022.

In order for 988 to work in the 620 and 785 area codes, 10-digit local dialing must be implemented, causing a change in the way you place local calls. Additional area codes affected are listed by state at the end of this help article.

What will be the new dialing procedure?

To complete all local calls, you will now need to dial 620 + seven-digit telephone number or 785 + seven-digit telephone number. This applies to all calls within the 620 and 785 area codes that were previously dialed with seven digits.

Who is affected?

Anyone with a telephone number from a 620 or 785 area code will need to make this change from seven-digit local dialing to 10-digit local dialing.

What do 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 seven-digit local numbers will need to be reprogrammed to complete calls to 10-digit numbers. 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 remains 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 + three-digit area code + seven-digit 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 800.273.TALK (8255)
