The first three fields contain a total of 7 digits that identifies a block of 1,000 telephone numbers assigned to a wireless carrier. These 7 digits, representing the area code, exchange and 1st position of the telephone number, must be matched to the first 7 digits of the prospects telephone number.
Each area code has 792 prefixes or NXX codes. Each NXX has 10,000 possible numbers. Therefore, theoretically, there are 7,920,000 telephone numbers per area code. In reality, since carriers need test numbers and other codes, not all of the telephone numbers are utilized.
