8,000,000 million telephone numbers are possible with these conditions, corresponding to the numbers 2,000,000 - 9,999,999.
Many countries have forced dialing of the area code now, creating telephone numbers with a minimum of 10 digits. This means there are 8 million possible telephone numbers in each area code. (area code of 3 digits long).
