9,999 if zeroes can be used than it would be 10,999
First of all, a PIN number is an recursive phrase because the N in PIN stands for number! There are 10 PINs of 1 digit 10*10 = 102 PINS of 2 digits, 10*10*10 = 103 PINS of 3 digits, and so on. In all, that makes 11,111,111,110 PINs. Some of them, such as 0, 0000 or 1234 are very insecure, but security of the PIN is not relevant to the question.
