How many combinations are there for a phone number with out area code?

It depends first and foremost on how many digits in a phone number, but also on restrictions for various digit combinations. In the United States, the first digit of a 7-digit local phone number cannot be 0 or 1, and the first three digits cannot be certain reserved combinations like 411, 911, or 950. The result is that there are a bit less than 8 million possible phone numbers per area code.
