You could break it up into two 5 digit random numbers for a compound key.
Thus giving you 32,768 X 32,768 , or 1,073,741,824, possible key
combinations.

SQL RAND() Function
This might be of interest to some of you, I wanted generate 9 digit random
numbers to sort a file in a random order. Turns out that though you can
indeed generate a 9 digit random number, RAND() will only provide 32768
unique values. I expected more given that it returns a double precision
float, but 32768 is all you get.
