Answers Three Number Lock Combination Calculator

How many combinations does a 3 number lock have?

This is a lock combination question. Even though people say combination, the math is permutation with repetition because the three ordered positions can repeat and changing the order changes the code.

Exact result

216,000

A 3-position lock code with 60 options per position has 216,000 possible codes.

A typical 3 number lock uses values 0 through 59 on each position, so each of the 3 ordered positions has 60 choices. Repeats like 00-00-00 are allowed, so the total is 60^3.
