Any 3 from 10 in any order = 10 x 9 x 8 = 720
It depends on what other restrictions you place on the numbers. For example, in North America (country code +1 = USA, Canada, etc.), area codes cannot have 0 or 1 as the first digit, and cannot have 9 as the second digit.
The answer is 720 different area codes. This is how you calculate it. There are 10 different numbers for the first category, then 9 for the second and 8 for the third, then you multiply those numbers in this order: 10 x 9=90, then 90 x 8=720.
If you include 0000, ten thousand unique four digit codes are possible.
10*9*8*7*6=30,240
As far as I can tell, all 5 digit numbers are potential zip codes, so there are 99999 + 1 potential zip codes, or 100,000. Many of these are not actually is use.
The number of 4 digit codes, using different digits, is 10*9*8*7 = 5040. However, computer passwords can, usually, have repeated digits and, if that is allowed, you can have 104 = 10000 codes.

there are 37 different codes this was wrote in 2012 so they might have created new codes in the future .
the repeated digits can lie in any of 3 positions:XXYZ,YXXZ, or YZXXTherefore, the number of different possible repeated digit combinations is 10×3=30 (there are 10 different possible digits).There are then 9 values left that Y could be, after the X's have their values, and 8 values left that Z could be, to ensure no unintended repeated numbers.This gives (10×3)×9×8=2160. There are therefore 2160 possible codes.

The Codes was created in 1966.

Codes in the Clouds was created in 2007.
Clash of the Codes was created in 1994.
No, They are from different company and have diffrent syntax. Some of them coud be simlar
