Starting Saturday, all local calls made within the North Carolina 336 area code must be placed using the 10-digit telephone number, whether using home telephone service or cellular service.

The 10-digit number is the area code plus the 7-digit local telephone number.

The North Carolina Utilities Commission said it ordered a 743 Area Code Overlay for the area currently assigned the 336 area code to ensure a continuing supply of telephone numbers.

This means that two area codes, 743 and 336, will now be used in the geographic area that was covered by 336 alone.

Generally, the affected area covers the Piedmont, including the cities of Greensboro, Winston Salem, High Point, Kernersville, Burlington, North Wilkesboro, Roxboro and Asheboro.

The North Carolina Utilities Commission provided the following details about the change in a prepared statement:

  • Beginning May 23, 2016, customers in the 336 area code region requesting new service, adding an additional line, or in some cases moving their service, may be assigned a new number in the new 743 area code.
  • Existing telephone numbers beginning with 336 will not be subject to change, unless such a change in service is requested.
  • Your telephone number, including current area code, will not change, but may if you move your service or add an additional line.
  • You will need to dial 10 digits (area code + 7-digit local telephone number) for all local calls.
  • For billing purposes, what is now a local call will remain a local call, even though 10 digits instead of 7 digits must be dialed.
  • You will continue to dial 1+ area code + 7-digit local telephone number for all long distance calls.
  • The price of a call, coverage area, or other rates and services will not change due to the overlay.
  • You can still dial just three digits to reach 911.
  • If 211, 311, 411, 511, 611, 711 or 811 are currently available in your community, you will still dial these codes with just three digits.
