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.
The number of digits in a phone number depends on the county of the number itself. For instance, in the United States, there are typically 10 digits for a number, whether it has an area code or is toll free.

A valid phone number in Croatia typically consists of a country code (+385), followed by an area code and the local number. For example, a complete Croatian phone number might look like +385 1 234 5678, where "1" is the area code for Zagreb. Mobile numbers generally start with "09" followed by eight digits, such as +385 91 234 5678.

There is no known phone number that consists of 000-000-0000 because there is no area code 000.
No, a 10-digit phone number that is missing the last three digits can not be a legitimate number. In order for a number to work, it must have 3 numbers for an area code and seven digits for the phone number itself. Some telemarketers are now using fake numbers to hide from the people they're calling.
