Mandatory 10-Digit Local Dialing

Over the next few months, everyone nationwide will be required to use 10-digit dialing.  Many of our local phone providers are requiring 10-digit dialing this month. When you call anyone within the 865 area code, you will need to use the entire 865-xxx-xxxx phone number; if your campus phone requires you to dial 8 + (the number) for an off-campus number, dial 8 + 865-xxx-xxxx to complete your call. Please note: 5-digit dialing for on-campus calls will not be affected.

What can you do to prepare for this change: 

  • Starting now, use the whole 10-digit phone number when making phone calls. 
  • Update the phone number for any contact you have saved on your cell phone.  Be sure to include the area code for any local phone number. 

Why is this change happening? 

In response to increasing national concern over the national suicide rate, the Federal Communications Commission (FCC) has adopted 988 as a new number to connect calls to the National Suicide Prevention Lifeline in the United States. You can also reach the Lifeline by dialing 1-800-273-8255 (TALK). 

What Will Remain the Same? 

  • Telephone numbers, including current area code. 
  • Dialing emergency and special services (e.g., 911, 711). 
  • Domestic and International calling rates. 
  • Long-Distance and International dialing. 
  • The National Suicide Prevention Lifeline can continue to be reached by dialing 1-800-273-TALK (8255).
