Mandatory 10-Digit Dialing Coming April 23, 2016 Effective April 23, 2016, 10-digit dialing (area code + the seven-digit telephone number) will be necessary for local and expanded local calls to be completed due to North Carolina’s new 743 area code which will overlay the 336 area code in the Piedmont region including the cities of High Point, North Wilkesboro, Winston-Salem, Greensboro, and Asheboro. You won’t have to change your present telephone number! The new 743 area code will be assigned only for new telephone numbers within this area code region, so the only change will be the way you dial local calls. This dialing procedure will apply to current 336 telephone numbers as well as new numbers assigned the 743 area code. • It will not be necessary to dial a “1” or a “0” when dialing your local and expanded local calls. • Local calling areas and rates will not be affected by this change. • Special services that use three-digit numbers, such as 911 and 411, as well as 1+10-digit “long distance”, will not change. • Other three-digit numbers that are currently available in your community or from your provider, such as 211, 311, 511, 611, 711 or 811, will not change.
