No. For any base, n, you use the digits 0 to (n-1) for all numbers within that system. If, as in the case of the hexadecimal system (base 16), 0-9 are not sufficient to take you to n-1, you "borrow" some letters of the alphabet. In this case A ,B, C, D, E and F.
Hexadecimal
The number of digits in a valid credit card can change depending upon the type of card. Mastercard and VISA use a 16 digit system, while others including American Express use a 15 digit system.
A quadrillion has 16 digits.

16 The current hexadecimal system was first introduced to the computing world in 1963 by IBM.
the binary system is base 2 and the hexadecimal system is base 16
The decimal system we normally use is base 10. That means that each position has 10 times the place-value of the digit to the right of it.Binary is base 2. Hexadecimal is base 16.

The hexadecimal system is base 16.
working with bases means to change the numbering system that you currently use. For base six, it goes 1,2,3,4,5,10,11,12,13,14,15,20. Looking at the sequence we see that "20" in this case is 12 of base ten..the numbering system we use. So "15" is 11, "24" is 16, and "31" is 19. You can work it from there.
