It depends on how many digits in an area code. North America (USA, Canada, etc.) uses a uniform system of 3-digit area codes, but many other countries do not.
Assuming a 3-digit area code and no other restrictions other than "first digit not zero," that leaves 900 possible area codes.

How many possible 3 digit area codes can be created without repeating a number?
The number of 3-digit numbers with no repeated digits is simply 10x9x8 = 720, if you allow, for example, 012 as a 3-digit number. There are 10 digits, any of which might be the first digit. The second digit can be any digit except the digit that was used for the first digit, leaving 9 possibilities. The third digit then has 8 possibilities, since it can't be the same as the first or second digit. The actual number of possible area codes will be lower, because there are additional restrictions on the number combinations for a valid area code. For example, in North America (USA, Canada, etc.), the first digit of an area code cannot be 0 or 1 and the middle digit cannot be 9.
How many codes are possible with 2 letters and one digit if no letter or digit appear more than once?
There are 26 choices for the first letter, 25 choices for the second letter (since we can't repeat the first letter), and 10 choices for the digit. Therefore, the total number of possible codes is: 26 x 25 x 10 = 6,500 So there are 6,500 possible codes with 2 letters and one digit if no letter or digit appears more than once.

How many 3-letter codes can be formed from the letters in the wped picture if letters cannot be repeated?
The number of 3-letter codes that can be formed without repetition is equal to the number of choices for the first letter (4 letters), multiplied by the number of choices for the second letter (3 letters), multiplied by the number of choices for the third letter (2 letters). Therefore, the total number of 3-letter codes that can be formed is 4 x 3 x 2 = 24.
