It depends on what restrictions you place on the three-digit numbers that are usable as telephone area codes. There are 1,000 three-digit numbers, if you include every combination from 000 through 999. In North America, though, 3-digit area codes have significant restrictions. The first digit cannot be 0 or 1 and the second digit cannot be 9. Area codes of the form N11 are not allowed due to conflicts with short codes for things like emergency services (911) and TDD relay (711). Other area codes with the second and third digits the same (such as 800, 888, 844, and 900) are reserved as "easily remembered" codes. That brings the total down to 648 regular area codes plus 64 special "easily remembered" codes.
