Determination of a New Area Code:
A systematic process determines where and when to introduce a new area code. The need for extra telephone numbers increases with the development of rural areas and cities. The North American Numbering Plan Administration (NANPA) is responsible for studying the growth of the regions and monitoring the needs of area codes in those regions. Therefore, this organization predicts whether there is a need for a new area code or not.
A single area code can serve approximately eight million dissimilar seven-digit telephone numbers. However, all these numbers are not in use. For instance, a wireless-providing company can purchase phone numbers for 10,000 blocks. Because of this practice, an existing area code goes to exhaustion, even though all phone numbers are not assigned to actual people.
A state has the right to determine whether a new area code should be introduced for specific geographic regions within its borders. Remember, to make a call within the area code 657 or 714, you have to dial 1+area code (657/714) + seven-digit number. However, there is an exception for three-digit calls, like 611, 411, or 911.

Numerous phone scams are found to use the area code 657. However, phone scams also occur in other area codes. Some criminals can make you fall into a trap in order to extract your money or personal information. Therefore, you should stay alert and report immediately if you suspect any scam.
