What Is Area Code?
A three-digit code that identifies one of the telephone areas into which the U.S. and certain other countries are divided and that precedes the local telephone number when dialing a call between areas.
Why are area codes added?
Area codes are added when the current number expires.
In North America, each area code has a potential capacity of about 8 million unique phone numbers. Increased use of cellular phones, modems, and Internet access may require existing telephone number resources, additional area codes may be required, according to Nestar.
Once the new area code starts being assigned, there is usually a six-month period of transition, where customers are encouraged, but not required, to use the new code, but seven-digit. Dialing is allowed. After six months, callers are required to use the appropriate area code and telephone number.
