It is a telephone dialing procedure that includes the area code+ telephone number to make a call inside or outside the local area. Sometimes, the ten-digit numbers are prefixed with number 1 (trunk code). This is common in areas where overlays are implemented. 10- digit dialing format, looks like this 1+ area code+ telephone number, is also called national format.
As overlay plans have spread to more areas therefore 10-digit dialing in the U.S. and Canada is becoming increasingly common.
