In a 5-digit coding system, the maximum number of unique codes depends on the characters used (e.g., digits, letters, or other symbols) and whether repetition is allowed. The most common assumption for a "5-digit" system is that it uses the 10 numerical digits (0–9).Calculation: With 10 possible digits (0–9) for each of the 5 positions, and assuming repetition is allowed, the total number of unique codes is:10×10×10×10×10=105=100,000

Uuuuuuuuuhhhhhhh.....the math is slightly off..tlhat to have that many specific codes one has to use exponents.......AND then there is the letters....26 of them... NOW we have too get to the permatations....
