  • On the other side, for making toll calls, you will require 1 plus the 10 numbers.
  • Ten- digit dialing means making a phone call by dialing area code before dialing a phone number of that area (area code + seven- digit number).

When you want to make a phone call in an overlay situation from one area code to another area code in the same geographic area, then you must dial 10-digits because you and your destined area have the same 7- digit phone number but each would have a different area code.
