999.
Think about it 001 002 003.....etc.
It just goes in order up to the 999
plus 000 makes 1,000
To calculate an ordered sequence (a permutation), you take the number of options for the first choice, times the number of options for the second choice, times the number of options for the third choice (etc).
In this case, you have 10 options for each digit (0 thru 9), so: 10 x 10 x10 = 1,000
