The first three numbers are called the area code. Originally, the area code was based on the population in the area and the ease of dialing it on a rotary phone. So a 212 or 312 was very populated, while 909 would be a rural area. They originally only had a 1 or a 0 in the middle to accommodate the switching system. Now they can be any three digits as computer systems can handle the differences.

Assuming you can use the values listed, and the phone number is 7 digits (e.g. XXX-XXXX), then you can select 3 numbers for the first digit (0 is exempt) then 4 selections for the rest of the digits. So, 3*4*4*4*4*4*4 = 12288 phone numbers.

There are 8*9*8*7*6*5*4 = 483840 numbers.

Phone numbers should always be stored in a text format and never as in a number field. There are several of reasons for this. You never do calculations with phone numbers; you may have a zero at the start of a phone number, which would disappear if left in a number format and you may, as in this case, have other characters in a phone number that are not digits, which would not be accepted in a number format.

You may be unfamiliar with this esoteric invention called a "phone book" which gives the numbers for people and businesses in your area, but I suggest you look into it (and then look IN it).
