Area code rules
These settings are only required for countries in North America.
The area code rules determine which dialing rules must be used for dialing a number in the North American Numbering Plan (NANP). The number must be dialed differently depending on how far the number you wish to dial is from your own location. For example, a free call must be dialed differently to a chargeable call.
The target number to be dialed decides which dialing rules are used. The number's area code and the three digits which follow it are decisive.
