Answer: There are 16 million different phone numbers possible.

First, let's find the number of possible phone numbers without the area code. There are 7 numbers in a phone number. There are 10 digits for each position. However, the first one can't be 1 or 0, so there are only 8 options.

Multiply the possibilities to find the total number.

8 x 10 x 10 x 10 x 10 x 10 x 10 = 8,000,000

Since, there are 2 different area codes, just multiply 8 million by 2 to get 16 million.
